When I came into the market for a high end camera, I crossed DSLRs off the list due to their lack of really usable live view mode. That eventually wound me up here, which is great and all... but lately the Sony SLT range, specifically the A57, A65 and A77, have caught my eye. Live view cameras, with all of the performance of DSLRs at prices comparable to MFT? Hmmm. A couple notes before we continue: * I have a GH2 and OMD. I'm not a stranger to the top of the MFT lineup. * I've never owned an SLR system of any sort, so the "bulk" everyone talks about here is just hearsay to me. I'm not really sure how much difference it makes. * I do a fair bit of video work, and the video aspects of the cameras are important to me. Not sure what lenses are video-usable. * I don't really care about imaging performance -- it's stellar all around, I already know. It's stuff like AF and the available lenses that caught my eye. * The GH2 is the likely candidate for replacement. I'm wondering what your experiences have been with the SLT cameras. Are they fun to work with? Are there any major problems? I've read complaints about things like back-focusing, overheating, and lenses being too noisy for autofocus use in video. On the other hand, the monster burst and AF performance is a big point of interest and f/2.8 constant lenses seem to be readily available for reasonable amounts of money. And although imaging performance isn't really a big deal, I am curious to hear about it as well. The DXO high-ISO scores are surprisingly low, maybe due to the pellicle? I'm also not sure how well they do with video, since even Vimeo is fairly low bitrate. I do know that the SLTs have AVCHD 2.0 with 1080p/60, which is very attractive to me -- but not so much if there's AF noise.
