Digital Concepts Powerzoom 952AF/CAN Flash for Canon Cameras

I have the Canon Rebel XT, XTi, and XSi and have used this flash on all of them. It is very easy use...especially compared to the Speedlite 430 EX that I use on my XSi. I am a semi-professional photographer and an Art professor. I use this for my XT, when I'm at work, both on and off camera. It has a slave flash setting that works well, but I mostly use a wireless transmitter when it is off camera (on a stand with a reflective umbrella). It gives off great, consistent light. The ETTL function is wonderful, but mostly use the manual setting since I use it off the camera. You can change ISO, speed, and zoom very quickly in manual mode. It also regenerates quickly for the next shot. People that give this flash a negative review need to remember 2 things: 1. if you are shooting the flash strait at an object or person, you really need a diffuser besides the built-in one that comes with the flash. I like the inflatable diffuser that acts like a mini soft box. 2. If you are trying to lighten up objects BUT reduce their shadow, you need to bounce the light off of the wall or ceiling. If you are in a room with high ceilings (church, gym, auditorium, etc.), then you will either have to bounce it off a wall OR get your diffuser out and shoot directly at your objects. So in short, the built-in diffuser is junk (just like the one in the Canon 430 EX) so get a soft box diffuser for it and it will be just fine. Remember, practice makes perfect...so get some NiMH AA batteries and start practicing angles, zoom, and speed. Once you know how this flash works and its capabilities, you will be very happy that you purchased this flash.

This product for Canon hum!!!!!!......
realy I can't talk, some time it's hard to use.
sometime not enoug light, the pics I took too dark.
sometime too much light, even I set it autofocus.
if I have more money let go up pick Canon light,
I hope it good then it many many.......time.

I purchased this flash and used it ONCE before it stopped firing completely. I contacted the seller and they exchanged it for a brand new one. After using the new flash TWICE, it did the exact same thing - except this time it stopped firing right in the middle of a friend's wedding I was shooting. Seems to me this thing is a P.O.S. ... I have contacted Sakar and hope they'll remedy the situation, but I won't trust this as anything but a back up flash in the future ... maybe not even that!

this is an outstanding flash!!! ETTL/E-TTL-2 compatible, GN 42m at 85mm zoom, very efficient focus assistant beam, automatically detect camera settings (ISO, aperture and focal length), flash ready indicator in view finder, etc..
the only downside is in the slave function: it's not TTL compatible, and it's triggered by the first detected burst of light, which makes it unsuitable for most digital cameras (if not all). digital cameras release 2 consecutive lights: the first one for metering while the second one is the real flash.
Even though the slave function is useless, i still rate this flash as 5 stars, because the canon 430EX doesn't have a slave option as well but has the same other functions for a price that is 2 to 3 times more expensive than this flash.
