Af280T is very good. I used it paired with K10D and the results are very good. I set K10D dial to the sync mode, then I set the aperture I want and enter the ISO/ aperture calculation in the flash, the photos came out very well exposed. Nice thing abt this flash is it has its own sensor etc, so you do not really need to use PTTL. It can swivel also and is compact in size. I paid $40 in craigslist
