I am considering one of the above flashes to use with my F5. I would get the smaller, lighter SB-28 but I hear that it only has flash compensation to +/- 1EV (that is a huge deal for me, as I want to go for subtle flash effects and will usually dial in at least -1EV) and that changing of settings isn't as quick as the SB-25/26. I also hear that the SB-26 has a now-obsolete wireless non-TTL flash control, which I will never need. Nor do I need a really wide built-in flash diffuser (20mm is the widest I will ever use, which is covered by the SB25). So I am leaning towards a used SB-25, but I haven't decided for sure. As far as I know, all three flashes support high-speed flash synch up to 1/4000 with my F5. I would appreciate any comments comparing the above flashes. Thanks, Dan
