I'm jumping off the Sony bandwagon this year. As a A700 user I was impressed by the quality of photos I was able to create with this robust camera but now that the entire line is being "upgraded" to SLT technology, I'm no longer interested in playing their game. Sony was a great value compared to other high-end DSLR's for a while but the move to SLT leaves me wondering why they haven't gone fully mirrorless like with their NEX series. I've decided to buy into Fuji's experiment with the X-Pro 1 because I believe eliminating the reflex mirror is the next logical step in pro-photography. Mirrors are loud, vibration-inducing and now a relic of the past as direct-view cameras are coming to market with usable resolution and features. Sony's SLT mirror is just another stumbling-block in the light-path of the imaging sensor. Fuji was kind enough to include an eye-level optical finder (that switches to EVF) for guys like me who use them extensively. I'm sad to see Sony using this "bridge" technology between the DSLR and mirrorless camera because the cameras remain bulky and have low-light performance issues.
Sony: go full-throttle into mirrorless or find a way to make the DSLR more relevant to the future of photography. SLT may just be an incredible waste of time and resources.
