It'll certainly be something "completely different" from other digital MF: it won't exist. Even though Sony appears to be trying the 'scatter gun' approach to camera systems I cannot believe they will want to develop a system that's in a segment of ever decreasing market share and something of a niche area now. They havent been able to make much inroads into the Nikon/Canon upper end of the DSLR market let alone MF.
I think this rumour's about as credible as the Canon MF one - CR 0.
The only reason the Full Frame vs Crop sensor debate isn't a Medium Format vs Full Frame is because of accessibility.
If Canon were to release a Medium Format solution, complete with new lenses many would drop full frame like a stone. As someone who shoots a H4D50 I can tell you there's no comparison between the two.
It's not even about MP for me either, 18mp is fine. Just massive pixels, large sensor please.
How much ever superior MF may be to full frame, which it must be, I cannot imagine dropping my 1dx. I love its fps and portability compared to MF.
Good point. But what if, in the future, perhaps in the second generation after the 1DX (not the next one coming in 2016, but the one after that), Canon has produced a lens lineup for an approximately 45mm wide sensor, that is similar to the current EF lineup...and this future "1DX" uses this sensor, and those lenses? (Those lenses in the same focal length, but not the same FOV
...need not be much heavier than the current EF lenses, because the image circle is not that much larger.) What if you could get different resolutions of sensor in that same body (with the high MP version limited in its fps at that resolution...but able to shoot in sensor crop mode...and the lower MP versions able to shoot at 16 fps with servo AF tracking)? And what if this camera body, is smaller than current MF cameras such as Phase One, and Hasselblad, but only slightly larger than the current 1DX...and weighing only ounces more, if that (and definitely lighter than the Leica S2). And what if it didn't cost much more in current dollars (adjusted for inflation and other factors), than the current 1DX? What then? Would you say "no I am still going to stick to 'full frame', because that's what 35mm film used to be"?
A decade from now, not too many people will remember film. Kind of like how now, people don't seem to remember or care, what happened in the 1990's and early 2000's.
