It's area that matters for how many pixels you can stuff in there, and thus the resolution. Using the pixel density of the ~12MP Nikon D3, at 118 pixels per mm, a 42x56mm sensor would be 32.7MP. Linear differences don't really indicate the actual resolution differences, because they only indicate o

Obviously their marketing arms for various devices didn't speak to each other. The Marketing blurb for Photo CD's (6mp images), basically said that 6mp was the equal of 35mm. The document that contained that has apparently disappeared from the Kodak web site. That doesn't stop it from having

No Kodak was saying 14mp back when I bought my Nikon Coolpix 100 (According to the receipt I ran across the other day that was in early 1998). Now their sales literature may have said something different but that was the figure that I got from their website back then. IIRC, that was in compariso

Area is only meaningful to advertising copy writers. Presuming you are happy with a 3:4 image 645 is 1.75x the size of 35mm, if you want 2:3 it is 1.55x. So a full 645 format will allow about 1-1/2 times the resolution of a full frame 35mm. That is assuming a 42mm x 56mm format and the same ppi

Yes, but the native resolution numbers aren't that much lower unless you're looking t older lenses, and the area is a whole LOT larger. 645 alone has 2.7 times the area of 35mm. That's a lot of space to put pixels in. MF digital is comfortably up to 39MP now and there's likely room for more. -Adam

Actually Kodak's sales literature, (propaganda), originally said it was 6mp, oh yes and wonder of wonders their high end photo, ("professional"), CD supplied 6mp. Funny how it became 14mp when they offered products with higher resolutions... (and they wonder why no one trusts them...) graywol

Actually, IIRC, with few exceptions, medium format lenses have lower native resolution figures that 35mm. They don't need it due to the size of the photosensitive surface they're projecting an image on. Adam Maas wrote: > I dunno about that. The 1DsmIII is pushing the limits of what 35mm > glas

Things change. I can remember when all a photojournalist needed was a couple of Leica bodies and 3 lenses (35,50,90). Before my time he could get by with a couple of Rolleifexs; and before that all he needed was a Speed Graphic with one lens. There was quite a bit of argument about what resolut

Funny. I remember about 6 years ago when people claimed that we would need 24 MP to equal 35 mm film. If anyone had actually described today's situation at that time few would have believed them. Besides, I could never affros that Canon. Or better, I could never justify paying that much. Steve

I dunno about that. The 1DsmIII is pushing the limits of what 35mm glass is capable of. While a ~22MP 645D wouldn't necessarily compete well (Although the Mamiya ZD back is selling every unit Mamiya can push out, at a similar cost to the 1DsmIII) a higher-rez unit might well be competetive, and the

An interesting user review of the new Canon 1Ds MkIII, which confirms my feeling that the 645D was swimming upstream without the spawning possibilities... http://www.luminous-landscape.com/reviews/cameras/mada-iiis.shtml I would consider this very bad news for an eventual 645D if it were ever
