I've had quite a variety of digital cameras over the years but recently bought the first one that supported an external flash. After having the camera for a few days I decided I would try this flash as it was a decent value and had decent reviews. Now, I am by no means a photographer. I have worked with digital cameras since some of the very early consumer grade cameras became available (think 320 x 240 resolution - LOL) but I do not claim to fully understand all of the photography jargon or most of the settings on my camera.This unit attached to my camera easily. I slide on firm but that may loosen up a bit after I use it more. As a ""techie"" I generally ignore the manuals and this was no exception. The device is simply to use and simple to adjust. My first picture turned into a total white-out because the flash is THAT BRIGHT. By adjusting the intensity a bit and flipping the flash so it was at a 45degree angle, my next picture and all of the ones since have turned out very well. Tonight I took my camera outside and took some pictures zoomed into a tree about 15-20 ft away and at an angle. It was after dark and I purposely turned all other exterior lights off just to see how the flash performed. Without any problem I can see the details in the leaves on the tree like I was standing over a leaf in broad daylight.I would certainly recommend this flash for anyone who like me is just getting started with this level of photography.
