Yesterday I got a flash unit for my DSLR which is the Canon Speedlite 420EX. Here's a video review of it.
As you can see, it doesn't comes boxed but it is in a very good condition. I hardly believe the condition because it's like buying it first hand.
The guide number for this flash is 42 (ISO100) and the main disadvantage is the ability to control the power. However, it still gives enough lighting for my daily usage as it can tilt and swivel to bounce the light.
That's all for now. Thanks for watching my video.
