I think that people are wrong to expect a fully functioning Canon lens on the Sony camera. You can mount it, and perhaps it will autofocus, but will it focus accurately? Will it track? Which focus points work? How accurate will the exposure be? Can you control the aperture??
Who cares?? (ok, maybe the wildlife guys wanting FF with more reach, but as we said this is just a hold over to see if Canon delivers or not)
If you are a Canon user you are getting it for the MP/DR for landscapes most likely. You are not replacing your 5D3 or 1DX or 7D with this, it's a supplement. A hack to get the DR Canon refuses to deliver to so far.
(ok well everyone would care about the aperture control, but yes the adapter absolutely allows you to control that, it's not an issue; and as for exposure I don't know it shouldn't be able to do it with Canon lenses, but even if it got 00, who cares, it's landscape you are probably doing M mode anyway or could easily enough swap to that, yeah sure it's all a little less convenient at times, as said, it's a hack to get more MP/DR for landscapes using Canon glass, but not that big of a deal and if you can't manage to get to the proper exposure pretty quickly on your own with a digital camera even if the metering isn't working at all then I doubt you even know waht DR or perhaps even MP even are)
