    Size, which does matter after all...

    Medium format negatives start at 6x4.5 centimetres (actually it's a bit less than that), which gives you 2.5 times as much area as 35mm. Using 120 roll film, which is 6 centimetres wide, there are a lot of 6x6 and 6x7 format cameras out there, and you can get 6x8 and 6x9. That is a LOT of negative, and usually a lot more detail than 35mm.

    Large format is even bigger. The negative sizes here tend to be given in inches, so 4x5 is at the smaller end, with other common sizes being 5x7 and 8x10. If you thought medium format gave you a lot of detail on your negative, that's nothing compared to LF, which I've only read about but which I'm told can be absolutely stunning.

    Then there is ultra large format. Ilford made a batch of special order sheet film earlier this year in sizes up to 20x24 inches. I can only imagine the size of camera, but think of the information you could get in such a huge negative.

    It's not just a matter of the quality of the neg/tranny produced.
    Larger format cameras have much larger viewfinders which means that the image you see is also much bigger. You can see far more of what is going on.
    With large format (5x4 and above) you can actually go over the ground glass viewing screen with a magnifier to check spot focus.
    Large format (and some medium format within limits) give you camera movements to which allow you to control the plane of focus, correct converging verticals, shoot into mirrors without getting a reflection (I love that one) and to distort shapes a little.

    After 20+ years of shooting 35mm, I got my first medium format camera a week ago. It's only a 645, but you are quite right - the viewfinder is amazing.

    Even so, I can see the day coming when I'll need to go to 6x7 and then to LF. There is a guy over on APUG whose signature line is "Did I mention that 5x4 looks small today?". Which it probably does.

    The way it's been explained to me is with a digital camera let's say you have 8 megapixels. That's 8 million "pieces" of information for that picture. With a medium format negative (or transparency) if you were able to count all the grains of silver on the emulsion you would probably be in the tens of billions! So, in effect the difference is 8 megalixels -vs- 10 gigapixels...

    Even then, I don't think you'd get the quality enlargements from a MF digital as you would from a MF slow ISO film. I may be wrong (certainly not a pro at this) but even with MF digital pixel size limits clear enlargements to 16x20 or 20x24 before you start seeing "grain" or "noise". And, the last time I heard I think a digital back for a Mamiya 645 was something $10K - a Hassie back in the $15K range.
    Like I said - I may be wrong so please correct me if this is bad info...
