Your correct, Michael did. If Michael has the opportunity to test more it will be helpful to affected lens owners.
Because SONY have elected a multi format ''alpha system'' approach, it does mean they may be designing FE lens with ray paths more akin to the A mount lens and adaptor for compatability reasons across their range.
This is great news to EOS owners, but not so good for M owners etc if affected on wide glass...
Their approach is quite clever really. NEX lens users can still shoot these bodies cropped. FE as standard and A by adaptor. The FE lens and A by adaptor back compatible with NEX bodies too...
For A mount sports shooters their existing lens and SONY adaptor will allow semi mirror reflex PDAF and one a7R reviewer has already suggested this combo is faster than a current alpha DSLR style body possibly due to the higher speed processing in these new bodies!
Well as an A Mount user myself that adaptor with PDAF is bulky and quite expensive too, so add that to the cost of the A7 body and it's not that attractive price wise. Granted more attractive than the A99, but that model is seriously overpriced anyway and was from day one.
I agree the problems likely will not be issues with adaptors and increased lens to sensor distance (ie SLR lenses), but for native lenses that A7 presents a problem. It's quite likely going to have worse performance v the A7r esp when wider angle lenses turn up. Obviously native lenses again will cause problems with acute angles hitting the sensor.
Unless Sony have decided to make lenses "more telecentric" I say more because you can't do much for ultra wide angles here. Maybe that's why the lenses are "bigger than expected" but that would not make sense for a long term strategy either..why compromise lens designs on the basis of one sensor?
I can't help but think Sony have made quite a serious mistake here. IMO the A7 should have offset micro lenses too, it has to as this type of design simply isn't going to work very well for shorter focal length lenses. I can see this taking the shine off of the 24mp model, I'd imagine a few have already cancelled their pre-orders..esp M mount users.
