Petroglyph: Tilting LCD on MF. It makes excellent sense to me. Also an ultra wide 645 lens. I wonder how many $$$ for that one.
bossa: I was hoping for a mirrorless version to get the size down to a D800 or D4 but they've stuck to the previous format.
Mirrorless would have reduced its market potential with about 90%. Mirrorless are less than 1/5th as popiular as DSLR's in the lower price brackets. At the 645D's sales point it is even worse.
Ayoh: Looks like it might do video judging by the Mic and Speaker holes visible on the left side of the body
And the new zoom has built in stabilization too looking at the switches
Should be a really impressive piece of kit, and 1/2-1/3 the cost of the competition.
Shallow DOF like 1.0 to 1.4 is about 0.000001% of all images taken and most of them are useless or would have been improved upon stopping down. Low light imaging is the primarly use of ultra fast lenses. Shallow DOF is the least of your problem when shooting MF which is why most MF photos are shot at F:11 to 22.
Simon Says: Anyone who follows the tech industry knows that history suggests that any sort of "medium", be it floppy in the very distance past, discs, CF/SD, etc. shrinks over time, while the performance of next generation but smaller medium initially doesn't perform as well, will catch up and surpass the standard of yesteryears.(For details on this subject: check out "innovator's dilemma")
Sensor is just another example of a medium for light, and there is no exception.
We are already experiencing this trend from Medium format -> FF -> APS-C -> 3/4 -> ?
Trust me, at some point smaller sensors will be technologically advanced enough to be just as good as bigger ones of the past.
For film it was the smallest format that delivered adequate results that won. I believe we will see the same for digital. If anything, better sensors will make smaller sensors more viable....
