Im EXPECTING a A99II to be killer good. The AF here does worry me some if that is something you are really going to need to be fast and in low light. Here it has the low light but I do question AF speed and accuracy. Right now for those type of shooters IMHO get the A77II for now and/or wait for the A99II. I would like it to be 36 mpx with a crop factor of 1.5 option as well. And the rest you mentionedGuy, just wait for the the A99II . I´m sure it will be a high iso monster, with crazy fast AF, dual sd slots, in-camera 4k video and IS!
The A7s is very very tempting for me as it would kill when the bride and groom hit the very very dark dance floor. AF does worry me though.
Is the 24-70 the widest option in native mount for the A7? If so, does anyone have comments on performance at 24? I have just the application for this A7s but it needs a wide lens.

Thanks Guy, 16 would work, I have an aversion to adapters, irrational I know but there it is. I'm instructing aurora courses this winter and this could be the camera for stars and aurora shots, only need manual focus and a remote trigger.For now native it is the 24mm as the widest. 16-35 we are just waiting for release , my money says Photokinia. You do have the option of using a A mount 16-35 which is said to be very good with the Sony LAE-4 adapter. I use this adapter for my A7r and my A glass today. One issue is you only get AF points ala the A99. So center 9 points and it is still pretty darn fast AF. Obviously you have 3rd party lenses options as well.
An electronic first curtain shutter should be sufficient to eliminate vibration in almost all shooting scenarios - any vibration from the closing of the second curtain would propagate long after the exposure is over. The reason a fully electronic curtain is not implemented more often is due to limitations in how fast the sensor can be read for a complete exposure - this creates motion and rolling shutter artifacts, even on the A7s which has a very fast read-out.I just received the A7S last week and have not really had a chance to work with it yet. However, two things are clear so far. First, the files at 12,800 ISO look really clean. This opens up possibilities for me in using this camera that simply were not there before. I am headed to India for three weeks in October and will spend lots of time roaming around and photographing at twilight and beyond. I am very excited about being able to shoot in very low available light. I don't need the high ISO feature for action, just (very) low light travel photography. Second, the electronic shutter is amazing. Sony just completely eliminated ANY shutter vibration. What a difference this makes in hand held shooting. What a difference this makes in tripod shooting with longer lenses. I wonder what technical limitations prevented Sony from introducing this feature on the A7R. Will we see it on the A8?
This is great news. With respect to M-mount wides, is the improvement limited to just colour cast/vignetting or is there also less smearing?Well, it wasn't long, and I am back in the Sony Fray with the A7s. My decision hinged on it's capacity to be a body for M lenses. I had come to the conclusion, that in general, the camera best suited for M lenses is an M, but going back over the past few months of shooting, I did enjoy using the A7 both with native and M glass. Now the news that the A7s plays well with wides, and I decided to jump in, especially given the low light capabilities. At very first glance, the silent shutter function should be fantastic for most of what I shoot....that is, composed street shots...And at first blush, the sensor seems to do better with wide M's, the 21 super-elmar in particular....At the moment, I have no FE lenses, so it's going to be M lenses all the way, for a bit at least....fun fun fun!
Thanks Ashwin. This is very helpful. I no longer have this lens but if I recall correctly it had to be stopped down to about f4 before it was sharp across the frame on my M9.28 cron, wide open, ISO 1000, A7s....
This is a very very rough test. Camera was handheld, shutter speed 1/2000 of a second, ISO 1000. No processing in LR other than "auto" exposure....
