Olympus FL-50 Electronic Flash for Olympus Digital SLR Cameras

I have an Olympus E-510 and i can not be more happier with the purchase of the FL-50. My indoor pics looks ten time better specially when you learn how to bounce light... You can be very creative... In short, highly recommended....

Holga Manual Shoe Mount Flash with a GN of 22'

This flash, being used with a Holga 120N doesn't do anything more than is advertised. For the price though, it is a great product. It fired on time, every time and works surprisingly well in closer distances.

Nikon SK-E900 External Multi-Flash Bracket Unit for Nikon 4500 Digital Camera

I already owned a Speedlight SB-28dx for use with my F100 on a Stroboframe bracket for off-camera flash. The SK-E900 enables me to use the same flash on my Coolpix 4500. It is a practical accessory for the Coolpix 900 series and 4500 digital cameras, as long as you don't mind investing in another flash or already have one. Your camera will automatically meter the light and adjust the output of both the built-in and external flash. Results are superb. Simply, it attaches easily, it is light, and it is well balanced.

Nikon AS-E900 External Multi-Flash Adapter (no bracket) for Nikon Coolpix 900, 990, 995 and 4500 Digital Cameras

I was hoping at least one of the 3 extension ports would be a standard flash single pin extension. But no, they are all the Nikon 3 pin connector so all u can connect is another Nikon device with the 3 pins. The shoe is standard.

Olympus FL-36 Electronic Flash for SP series, C7070, E1, E300 & E500 Cameras

I chose this flash due to my budget. But have not been disappointed. It may have a slow cycle time. In my type of photography with light, controlled environment that has not been an issue. For macro photography of animals/insects it has not seen that much action lately. Waiting on light stand to try out some strobist style shooting with this flash.

Canon Speedlite 420EX Flash for Canon EOS SLR Cameras

Excellent performance and value for the money. The Canon 580 EX is best, but for my purposes this unit is just fine.

Sony HVL-F36AM High-Power Digital Camera Flash for Sony Alpha Digital SLR Camera

This does what it is supposed to do. Good Guide number, wireless capabilities, bouncing capabilities, High speed sync(even in wireless mode), manual zoom.

I am very happy with its performance. It gave me correct exposure with Sony A700 and A100. I prefer to use it in wireless bounce mode with camera in manual meter. This is a must for every Sony DSLR owners.
