Idea: mirrorless DSLR ... with mirror?
#11
With a pellicle mirror and EVF, the camera could actually eb less high and still provide blazingly fast AF with lots of AF points. Thisbecause the AF system could either reside directly behind the mirror or above it where the focusing screen is now, and obvious the sensor assembly would have to be in the other place, either behind pellicle mirror or where the focusing screen is. This would also provide for extra room either in the "pentaprisma" housing, or in the area behind the mirror, so that maybe some more electronics could be moved there, providing more space for e.g. a larger battery, or even a narrower camera if the battery would stay the same size.



Would we gain much with current technology, size wise? Probably not, but imagine a camera less wide than the 5D II, probably by about 5 or 6 mm, and less high as well, by about 2 or 3 mm (maybe a little more if the pentaprism housing could be made less high too), however with the AF system of a 1D Mk IV <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />. Since the mirror doesn't have to move anymore, it could probably do 20 fps too, if the processor(s) is(are) up to it too. Although with those specs, you'd probably need a lot more battery <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />.



Personally, I would want an EVF with a resolution at least in the full HD category, with no visible or noticeable ghosting before I would consider such a system... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />.

The sensor on top can't be in a sealed chamber...

Doh! I was still thinking of the rumoured Sony arrangement not the "top sensor" layout.

off on a tangent for me as per usual - but i'd rather like a leica for the small is beautiful set - and off on another tangent, seems to me that live view to ipad might be interesting for the great outdoors . . . if you weren't in a hurry for the shot and liked to see more than the little screen -

. . . or what about a view camera [Image: rolleyes.gif] . . .

I wouldn't mind a Caneica <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />...

If you don't mind 7", full HD, this is already possible at a reasonable price. After all, this is what videographers using dslrs like 5D II and 7D use for focusing etc... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />.

That's possible too. Several view camera maufacturers have adapters for using a Canon or Nikon body in the film plane <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />.

Absolutely. Especially since it comes with full frame (or slight crop (M8)) but still very compact lenses. But also all sorts of restrictions.

The first time you try to read something on an iPad display outside in sunshine you'll realize this is not the tool you want to use for this kind of application <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='Big Grin' />
