    Re: Jumping to MF! Some dutties..

    Ah all this talk of the different systems makes me want to try them all.

    But I have my heart seemingly set on the contax. I just wish I had more time for shooting.

    I wish I hadnt spent money on a phase one V mount adapter plate for my rz67! Ugh.

    Marc, not sure why you say this about the Leica S. You consider your H4D-40 as a "Medium Format sized sensor", don't you? The Leica sensor is 1350 square mm in imaging area; the H4D-40 is 1460 square mm. The Leica sensor has a 54mm diagonal; the H4D-40 has a 55mm diagonal (with a different aspect ratio).

    So they are pretty damn close, whichever metric you use. In fact, since they use the same pixel size and the same Kodak 3rd gen microlensed design architecture, that headline difference of 37 MP vs. 40 MP is all the difference there is. Can you really say that an 8% increase in MP & area makes one sensor sub-medium format, while the other leaps up to the status of true medium format?

    I consider both sizes to be medium format. And indeed the square 16MP backs of old, with an imaging area of 1350 square mm - by a remarkable coincidence, this is exactly the same as the Leica S!

    Easy Ray ... no slight intended. Of course these days we all consider anything beyond 35mm to be Medium Format I guess ... but only a few are actually 645ish, and none are 6X6 or 6X7 digital. I consider the 40meg backs to be crop frame MFD ... which is what they are.

    Most MFD cameras have been 4:3 aspect ratio and the S is 3:2 like 35mm is. The point being that the S system form factor and aspect ratio bridged the gap between 35mm DSLRs and the more traditional MF form factor and aspect ratio.

    Medium Format is really a misnomer in the digital age isn't it? "Medium or middle" implies there are larger digital formats like in the film days, when there aren't.

    BTW, the S2 gives up nothing against a 40 meg back.
