Excerpt: While I loved my pop-up flash on the A700 to trigger off-camera "real" flashes, it was the biggest sacrifice when I went to the A99. I have three Sony off-camera (well, could be used on-camera) flashes through their generations, and they are perfect with umbrellas and diffusers for studio flashes. Now I have the ability to fire them. And, in a pinch, the different orientations and diffusion options on the F20M allow for quick, creative flash in-a-pinch.
Pros: Easy To Use, Fast Recycling, Lightweight, long battery life
Excerpt: I bought this flash because I have the Sony 18-200 lens with a NEX-6 and the lens is so big that the flash incorporated with the camera makes a shadow. I only use it for personal photograph. So after some time with this flash I can say that has exceptional power, the height is ideal for any lens. No way can you make a shadow even with full zoom. It has two modes, direct and bounce. And it also has a removable filter.
Pros: Bounce Mode, Direct Mode, Durable, Easy To Use, Has Direct And Bounce Mod, No Shadows With Any Lens, Powerful Output, Versatile
