[/QUOTE] You can get wireless radio triggers for the sony mount. Not the TTL pocket wizards but many of the other triggers are available in the Minolta mount. As far as the pin configuration your absolutely right. Every manufacturer has uniques falsh mounts. Sure you can mount a Canon flash on a Nikon camera, but why would you want to? You can do the same thing with a sony with an inexpensive adapater. But again why would you want to? I can see using a different brand as an off camera flash in manual mode and this is easy to with the existing radio triggers for the Minolta mount. Interestingly, it appears Sony is dropping the Minolta mount in favor for the ISO shoe. As far as SLT I see know real advantage for it over a purely mirrorless design now that af sensors can be on the image sensor. I see the larger SLR form factor sticking around but I don't see any long term advantage of maintaining the SLT design.
