Sony Action Cam AS30V Review

Sony Action Cam AS30V Review

I got my hands on the latest Action Cam by Sony last week and I can’t help myself but write a review about it since it’s just super awesome. For those who didn’t know what an Action Cam is, it’s actually a camcorder targeted for those who indulge themselves with extreme sports (superbike racing, mountain climbing, surfing etc). Since nobody can see what the person is going through, a Point-of-View (POV) camera is suitable for such situation. It’s going to enable recording during such activities plus providing GPS data to keep track of your route. We’ll see what the Sony Action Cam has to offer.

Hardware and Design

Inside the small package lies the 1/2.3” type back-illuminated Exmor R^TM CMOS sensor with 12 effective megapixel for photos and videos. The lens is the ZEISS® Tessar® Lens if the highest quality and I have to admit, it gave such a nice and sharp shots of mostly everything that’s in focus. With the max aperture of f/2.8, it does provide a clear, sharp images and recordings. However, be aware that the minimum focusing distance for the Action Cam is 30cm and nearer than that would give you an OOF (Out-of-Focus) shots. Recording button on the back is quite flimsy but it does have a lock to prevent from accidental recording that would end up drying up your juice. Underneath the record button is the battery and memory card slot. The battery would last around 2 to 3 hours. Standy would last for a week I guess. The action cam can either too a microSD or Memorystick micro. I get a 64gb microSD since it gave much more recording time for me (around 5 hours of full HD recording or 10k plus shots). The two button on the side are for navigating the menus and a super-small LCD to show the menus. It was built with great aerodynamic since the wind resistance will be much less than the GoPro. The slot for microUSB, microHDMI and mic were placed on the bottom and covered with a flimsy hard plastic cover. Charging is definitely with the microUSB since it remove the hassle of taking the battery out and using the external charger.

Video

The Action Cam maxed out it’s recording at 1080p 60fps with 18mbps. Beside, it also has 1080p 30fps, 720p 120fps (SuperSlowMotion), 720p 60fps (SlowMotion), 720p 30fps and 480p. After using it on a few occasion (especially on my superbike), the Action Cam proved to be smoother though there’s few artefact which I believe came from the waterproof casing. Videos without stabilization will be at 170º and turning it on and you will get a little bit tight which is around 120º. That might be a lot but for me, it works best on some events. Most of the time I would turn off the stabilization just to get the extra view.

Photo

I would say it’s a mixed bag. This little cam is definitely not suited for photos but it does it’s job. Though it gave you 12mp of photos each time you’re on your own selfie, high noise is the drawback. I managed to get a great outdoor shot with great lighting but indoor is very much acceptable. Not very good but you can still see your own smile. Sometimes I would take clips from the video itself cos it looks much cleaner than taking a photo.

Accessories

Sony has thrown mostly everything you can think of. From the headmount to the chest harness, you name it. Mostly are upgrades from its little brother, the AS15V. What you will basically get right from the box are waterproof case, a curvy and a flat sticking mount. Others like the chest harness require you to blow some cash. The most significant of all the accessories is the LiveView Remote. It has a small LCD that act as a viewfinder and it would also act like a watch to show time. You can record from the watch which means you don’t have to go for the cam itself to push the record button. Changing the setting and view was made easy by the watch. It’s also waterproof. That’s why I get one.

Usage

It works great. Sometime, you can just hold it during your walk and you will still get great videos. The cam alone is not waterproof. It requires the waterproof case to make it waterproof and maybe a little shockproof. It will still break if you smash it on the floor though. I had great time using it in the pool with my friends and the SuperSlowMotion mode is very, very smooth. It’s just like peanut butter cream. The cam is built specifically for extreme sport users. However, if you’re a person who prefer travelling alone, this is also the one for you. You can take you own selfie or record whatever you’re going through your holiday. Since I travel alone with my bike, having this is a much better option.

Price

It’s a Sony. You can’t expect a low price. You think this is a junk? It was priced nearly the same with the GoPro3+. I got mine with the LiveView Remote watch and it costs RM1,499. The GoPro3+ was priced the same with a recording remote watch. I guess Sony’s watch is much better since it gave me a look at what I’m recording though it was like a bulk on my wrist. All the accessories were plastic and it’s gonna cost you premium price. Don’t tell people that I didn’t warn you for this.

Final Verdict

This is not a normal camcorder. If you think you’re getting this for your home video, you would better off using your smartphones for that. My Samsung S4 did better home video or even stupid video compared to the Action Cam. Get this cam if you are going jumping off the cliff, bungee jumping or even skydiving or even any other sports that is going to make recording impossible. Videos are smooth, shots are considerably acceptable and it is quite tough. Get this one if you’re going to do so extreme and crazy stuff.

Panasonic LUMIX DMC-G3

Check out the news on the latest 4/3 interchangeable lens camera from Panasonic!

SECAUCUS, NJ (May 12, 2011) – Panasonic today announces a new addition to the LUMIX G Series of Compact Systems Cameras (CSC), the LUMIX DMC-G3, the company’s smallest and lightest digital interchangeable lens camera with a viewfinder to date* . This new class of CSC offers a lighter weight and smaller size not seen in traditional DSLRs, thus providing greater portability and creative control. The LUMIX G3 features a new 16.0-megapixel sensor that produces rich, true-to-life, high quality images, plus 1920 x 1080 full-High Definition (HD) video recording capability with stereo sound in AVCHD. The Panasonic LUMIX G3 is the ideal hybrid, offering superb still and video capabilities with easy-to-use features so users at any level can create professional-quality images.

“With the LUMIX G3, Panasonic offers an extremely light compact system camera that is easy to use, thanks to a touch-control LCD, yet still maintains powerful and creative features to appease the more advanced photographer,” said Darin Pepple, Senior Product Manager, Imaging, Panasonic Consumer Electronics Company. “With new features that enhance photo and video quality, the LUMIX G3 offers exceptional image quality that a photographer at any level would be excited about using to capture their experiences.”

For the camera traditionalist, the LUMIX G3 provides a traditional DSLR-like experience with an external Mode dial for quick access to common modes like Program, Shutter and Aperture Priority, Manual. Additional dial settings include two Custom Modes, Scene Modes and a Creative Control Mode. The LUMIX G3 provides a dedicated video button that can be used to switch to video capture quickly without changing modes. Like most traditional DSLRs, the LUMIX G3 provides a built-in flash and hotshoe for connecting optional LUMIX flashes. For many, a traditional eyelevel viewfinder is still a must have, so the LUMIX G3 meets this demand with an eye-level electronic viewfinder that projects a high resolution 1.44m-dot image with 100% field of view (800x600, 0.7x magnification). In addition, color breakup has been improved when compared to the LUMIX G2.

To enhance operability and ensure it’s user-friendly, the LUMIX G3 features touch-control shooting, which lets photographers focus on the subject by simply touching it on the large, 3-inch high-resolution LCD touch screen. Once locked on the subject by a touch, the LUMIX G3 tracks the subject, even if it moves, with Auto Focus (AF) tracking. In addition to its 23 Area Auto Focusing Points, the LUMIX G3 features new Pinpoint AF. Pinpoint AF allows extremely precise near–pixel-level focus point setting at the touch of a finger. For example, unlike DSLRs that limit the number of fixed hardware focus points, Panasonic’s Pinpoint AF can be set by touch control to very fine points anywhere on the LCD. With a new Precision Contrast LightSpeed AF system, the LUMIX G3 is extremely fast, measuring approximately 0.1 second (14-140mm ~0.1 sec. 14-42mm ~0.18 sec., 45-200mm ~0.15 sec.). The LightSpeed AF feature is achieved by reducing the detection time for focusing by doubling the Live MOS Sensor drives speed from 60 fps to 120 fps. Manual control over focus is available in the LUMIX G3 and has been greatly improved when compared to its predecessor, the LUMIX DMC-G2.

When magnification is first enabled at 4x by simply touching the subject on the LCD, that subject is enlarged in a small window allowing you to keep the rest of the image in view as a framing reference. Beyond 4x, that small window fills the monitor so even more control over focus fine-tuning can be achieved. This handy feature is available from both the MF Assist (Manual Focus) and AF + MF focus modes.

The Intelligent LCD has a bright 1,440,000-dot equivalent resolution and rotates 180° to the side and tilts 270° up and down offering approximately 100% of field of view, making it easy to operate and shoot at different angles. In addition, the touch-enabled-screen operation excels not only for shooting but also for playing back images with outstanding visibility. Users can scroll through hundreds of images on the screen, simply by thumbing through the thumbnails. Or, to play back images one-by-one, the user drags the image across the screen as though flipping a page in a book.

The LUMIX G3’s newly developed 16.0-megapixel Live MOS sensor, combined with the powerful Venus Engine FHD image processor, contribute to the high-quality photo and video images. The processor also provides selective noise reduction to create a more naturally-balanced curve without deterioration of the image. In the LUMIX G3, noise is significantly suppressed by more than 66%. Notably in shooting at high ISO settings, S/N value is improved by approximately 200% compared with the conventional 12.1-megapixel sensor. The sensor performance improves by 6db at ISO 3200 and max. 9db at ISO 6400.

For added ease of use, the LUMIX G3 features Panasonic’s iA** and new iA Plus modes, which are enabled automatically once the iA button is pressed. Panasonic’s iA features, such as Intelligent Resolution, MEGA O.I.S. (included in several lenses), Intelligent ISO Control, and Intelligent Scene Selector are available when shooting still images. However, Panasonic’s new iA Plus mode adds greater flexibility with real-time visual feedback between automatic and manual shooting features:

• Touch-screen-slider-enabled background defocusing.
• Touch-enabled exposure control compensation.
• Touch-screen-slider-enabled white balance. A desired color balance result under difficult lighting can now be achieved visually from the LCD with a touch-enabled slider icon.  

The LUMIX G3 offers rapid burst shooting control at various rates and resolutions. Image capture at full-resolution (16-megapixel) is possible at up to 4 frames per second with its mechanical shutter enabled, or an even faster 20 frames per second using the electronic shutter feature at a reduced resolution of 4 megapixels.

With an array of creative features, the LUMIX G3 offers users the opportunity to express their creativity with settings like Creative Control mode, which allows for images to be taken with popular visual effects that previously required software post processing. Effects include: Retro, High Key, Sepia and High Dynamic.  The conventional film mode has evolved with a new effect control, Photo Style, which has Standard, Vivid, Natural, Monochrome, Scenery, Portrait presets that allow finer adjustment of contrast, sharpness, saturation and noise reduction by each.

As with many interchangeable lens cameras, dust on the sensor reduces image clarity. To eliminate this potential, the LUMIX G3 uses a Dust Reduction System that uses a supersonic wave filter in front of the Live MOS sensor. Vibrating vertically around 50,000 times per second, the filter repels dust and other particles effectively.

The LUMIX G3 utilizes the Micro Four Thirds (MFT) System mount, offering greater size and weight reduction in the lens without compromising performance and clarity. The LUMIX MFT System offers a selection of 11 high-performance fixed focal length and variable aperture G Vario zooms, including a highly-versatile 3D lens capable of capturing both 2D and 3D images at the same time. There are lens adaptors available for mounting older Leica M and Leica R lenses, including prior LUMIX full Four Thirds lenses. An innovative 14-140mm HD G Vario lens provides the best of video and still-image shooting with a long 10x range and near silent high-speed focusing. When connected to the LUMIX G3, ultra-fast focusing and auto subject track AF can be achieved. Many LUMIX MFT lenses come with MEGA O.I.S. (Optical Image Stabilization) built-in. This feature helps prevent blurring from shaky hands. Working together with this is the camera’s intelligent ISO Control, which reduces motions blur by adjusting the ISO sensitivity if the subject moves, helping to ensure sharp images.


The Panasonic LUMIX DMC-G3, made of aluminum, will be available in a variety of attractive colors, including black, red, white and brown, starting in June 2011. Suggested retail price of the LUMIX G3 with the 14-42mm Zoom Lens Kit will be $699.99. For more information about the Panasonic LUMIX G Series of compact system cameras, please visit www.panasonic.com/lumix.

After Effect - Samsung Galaxy Tab

Salam.

I have been using Samsung Galaxy Tab for a while and would like to share its pros and cons as a mobile phone and tablet. Hope such info will help you to determine whether you love it or hate it. I'm kinda standing in the middle of it.

Calling
Oh my! The worst part comes first. Calling is such a pain in the a**. Not just making it but also receiving it. Without headset, it seemed like the whole world is joining in the conversation. And I'm not joking. You can't have it near your ear and speak like normal phones, you have to face it. Damn its difficult! People will always look at you, thinking that you're some kind of sick bastard. Imagine a gadget freak being called that. 1 star for calling.

Messaging
Yes. This is heaven. The full QWERTY keypad is nice to the touch. I rarely made any mistakes. The threading in messaging keeps you updated if you are suffering from short term memory lapse. It feels like you are having a very big iPhone. 5 stars for messaging!

Multimedia
Its unbelievable that such gadget can have codecs for most of the files. My 1080p videos works fine and the audio is very good and loud enough to be enjoyed together. Music have no problems at all but the list seemed to be in a havoc. Using the 3.5mm jack has to be specific. Some earphones or speakers tend to suffer from echo problems as it has multifunction purposes. Normal headset works fine though. 4 stars for multimedia!

Games
The best part of this tablet. Its awesome. Having a big screen provides you with plenty of freedom with your fingers. You'll have precise accuracy compared to those small smartphones. Hoho. But the drawback is that you'll tire your fingers easily as you have to move them a lot. Dragging stuff here and there. And some games are not optimized for the large screen. But it's fun to play games on the big screen right? 4 stars for games!

Camera
Let me stress on this one. This thing is not a cameraphone. The quality will be rated as just nice. Its not excellent and not bad. What would you expect from a 3.2megapixel snapper? Its easily affected by bright lights but it works fine in outdoor conditions. Indoor with flash? Too bad. 2 stars for camera.

Gallery
Yes. Quite amazing. Viewing photos and images are great. With pinch zoom, you can play with your picture in anyway you want it. Basic on-spot editing such as rotating and cropping are also available. However, it is quite slow in scanning for images. Even if you have it done using USB cable. But the background is nice as it select photos at random. 4 stars for gallery!

Connectivity
Despite having Bluetooth 3.0, the latest that only Samsung have, the transfer still not as fast as it would be. I've tried it with my Samsung Wave which have the same 3.0 but the result is not promising. Even transferring a 2MB photos took quite a while. Wireless suffers no problems at all. Working fine. And I'm not pissed about that. 3 stars for connectivity.

Contacts
Very much appealed. Most of the basic detail are there and linking with Facebook and Twitter sprouts no mess-up. It even place birthday notification on the calendar automatically. Great job on contacts Samsung. Emails, address, phone numbers, up to annivessary are there. It even provide us with the latest activity with the contacts such as calls and messages. 5 stars for contacts!

There you go. Hope that will help you if you are thinking of getting a tablet mobile phone in the future. Of course there are two sides of the coins and sometimes you have to look for another coins.

Thanks for reading.

Taking care of your Smartphone's Screen

Salam.

Since most of you guys...and girls are using smartphones with touchscreen, let me share a few tips that can help you.

1. Use a screen protector.
A rule that's applicable to mostly everything with screen. Even if your are not touching them like PSP. It works as a cover to protect your screen from being scratch. Some of the most popular types of screen protectors are regular, privacy and anti-glare. Anti-glare would be the best as it prevents fingerprints and makes your phone looks solid.

2. Avoid pressing the screen.
Hey there dumbo! That's why they call it TOUCHscreen and not PRESSscreen! Since smartphones nowadays are equipped with capacitive touchscreen, there's no need for you to poke it with stylus or anything with pointed end. Everything will be fine with just your fingers. You wouldn't want to waste hundreds or thousands that you have invested.

3. Use a case or pouch.
Well? For safety purposes only. Yes. This is not just to avoid scratches on the screen but also on the body of your phones. Imagine lending it to your friend and suddenly BANG! There goes your wallet. The best case would be the leather case that cover both front and back side of your phones. Leather case have better shock absorbant compared to gel or plastic case.

4. Wipe the screen regularly.
Little by little and the damage done is irreversible. Accumulated dust and smudges can get through the screen protector and damage the screen. This is due to the friction of the dust and your finger that will eventually makes the screen protector goes thinner day by day. A little physics won't hurt right?

Casio ProTrek PRW5000Y-1

Salam.

All the goodies in a single watch so you won't watch anywhere else. Here is a new watch from Casio, the Casio ProTrek PRW5000Y-1. It comes with triple ABC sensor, solar charging, atomic time sync, compass and altitude/barometric pressure differential pointer.

Here's the official press release.

Casio America, Inc. is proud to introduce the ProTrek PRW5000Y-1 which is now part of its popular triple sensor timepiece portfolio. Equipped with cutting edge, Tough Solar Power technology made popular by its Pathfinder line, this newest model contains an analog/digital timekeeping format with a unique second hand that acts as a compass needle and altitude & barometric pressure differential pointer. It also utilizes Multi-Band 6 Atomic Timekeeping, making it the ultimate must-have timepiece for outdoor excursions.

Designed to meet the needs of outdoor enthusiasts and those who enjoy active and adventurous lifestyles, the hour and minute hands always display the time, while the second hand and LCD can display vital outdoor data, such as direction, altitude, barometric pressure and temperature. The hour and minute hands are specially designed with cut-outs for greater visibility of the dial underneath, which assists with reading the digital display and dial indexes. In addition to the compass, the ProTrek PRW5000Y-1 includes an altimeter, barometer and thermometer. With a resin band, the watch also provides a lightweight feel and enables consumers to reach the peak of style.

“We are thrilled to unveil the ProTrek model which builds on the rich history of innovation contained in our Pathfinder line,” said Shigenori Itoh, vice president of Casio’s Timepiece Division. “The ProTrek’s slim design provides a practical, yet stylish solution built for the everyday lives of consumers and their adventurous lifestyles.”

Through Multi-Band 6 Atomic Timekeeping the timepiece automatically synchronizes with Coordinated Universal Time broadcast continuously by stations linked to atomic clocks within the US, Germany, the UK, China and two in Japan, based on the user’s home city setting. Tough Solar Power adds to the ProTrek’s efficiency while the unique power saving function allows the watch to power down when not exposed to light for a certain period of time, thus conserving power. With Tough Movement, the ProTrek PRW5000Y-1 automatically checks and adjusts it hand home positioning at the 55th minute of ever hour.

The ProTrek’s one-touch triple sensor buttons lead to direct operation of sensors. This means no scrolling through menus to get the measurements you need quickly. Button guards prevent against accidental operation of sensors and enhance the practicality of the timepiece. The large textured buttons allow for easy operation in various conditions even when the consumer is wearing gloves. The ProTrek PRW5000Y-1 is available in black resin with an electric blue dial and blue IP stainless steel bezel for the MSRP of $480.00. The model will also be available in May at Tourneau and select fine Jewelers.

Imagine getting this thing for birthday. Then my head would explode with happiness.

Amazing Control of Porche GTR 3 Hybrid.

Salam.

Porche GTR 3 Hybrid. A super complicated controls. Maybe you'll need a special license to drive this beast.

With all the buttons on the steering, I guess this is a little too much to be on the road. The big red button beside the steering is some sort of nitro-boost button without nitros.

I believe parking this beast on the headmaster's parking spot won't cause any problems.

Nikon D5100

Salam.

Its been a while since I've posted something about photography. This time is quite significant as the Nikon D5100 just came out.

It's the evolution of the ol-Nikon D5000. Well, its quite difficult to tell whether its an upgrade or downgrade version from the D5000. Here I will laid out some key features of the D5100.

NIKON D5100 - Key Features
- 16.2 megapixel DX-format CMOS sensor
- Side-articulated 3.0" LCD monitor (920,000 dots)
- 11 AF points (with 3D tracking)
- ISO 100-6400 range (Up to 25,600 equivalent when expanded)
- HD movies (1080p, 720p or WVGA)
- 4 fps continuous shooting
- In-camera effects filters in both stills and video modes

Here are some obvious differences between the D5100 and D5000
- Higher resolution sensor (16.2MP vs. 14MP)
- 1080p video mode
- Wider ISO range (100-25,600 equivalent)
- Full-time AF mode (AF-F in live view)
- Dual IR receivers (front and rear)
- Side-articulated LCD screen (as opposed to bottom-articulated)
- 921k dot LCD screen
- 14-bit NEF (Raw) mode
- Effects modes
- No wireless control mode over the D5000
- No magnesium alloy build
- 11-point AF system vs. 39-point AF system

I am more particular about the features it holds rather than the picture quality because they uses the same EXPEED 2 sensor which only differs in pixels it holds.

Nikon manage to keep a balance upgrade from on the D5100 however the missing magnesium alloy body is quite depressing. Guess Nikon are also using Canon's strategy of removing the magnesium alloy build in their later upgrade (e.g. Canon EOS 60D).

Hope they'll use their head next time before trying out new stuff.
