I believe the Sony A900 also has a mirror motion that doesn't swing out that much. The front edge of the mirror does not end up very far forward from where it started when a picture is taken. It's more like the mirror is "pushed" up rather than a "swinging" motion.

Just sliding up (or a combination of both) may be plausible with a pentamirror setup if you relieved the corners of the side(roof) mirrors.  But with a pentaprism I don't see there being enough room.  Interesting thought though.

Do you happen to know if the A900 mirror or prism?

I do understand that a full size mirror with a normal swing motion would hit the back of an EF-S lens.

The mirror on the A900 is effectively getting the same result as Nikon( the "bigger" mirror moves back during the swing )

As far as I know, there is only ONE SLR have a side way moving mirror other than  a flip up mirror. It is the Olympus Pen F. That is another story. You can google it  if you are interested.

Crop mode was first introduced by nikon with their D3s/x cameras.

No, the D2x had it too. Shoot either at 12MP/5fps or cropped down and fast.
Thats a viable option if you're short on processing power or bandwidth.


As for cropping in post: thats throwing away perfectly good buffer space while burdening you with extra processing time. Doesn't matter in the studio, but if you want to be the first one to deliver your pics of an event...

Pentiprism.
A picture of the mirror motion is the 4th picture down on the right. A picture of the Prism is below.

I'm all for 24 MP 5DIII with 7FPS
Add better AF, reduced moire, improved high ISO, AF during video, pixel binning with crop options and I'd be a happy camper.
