24mm x 36mm = 864mm^2
600mm x 700mm = 420000mm^2
Given the difference.. WOW! I'm curious, I understand field work, action
shots, etc.. BUT, why would someone use a 35mm in the studio then?? 6x4.5,
6x6 or 6x7, just has such HUGE advantages it's not funny.. Ok, I'm doing
the math here..
and it seems to me, even if I want 4x6"'s, or 5x7"'s, there is very little
blowup from the negative if I do a 6x7cm. I mean less than twice... So if
I assume that the picture I took with a 6x7cm camera like a Mamiya was
50lp/mm, then on print of a 4x6, I might still have 35lp/mm of resolution!
WOW. vs. something like a 35mm, where I might have 12lp/mm... The Mamiya
lenses will generally yield 60-70 lines easy, just like the Zeiss optics.
>From reading, they say what is considered "sharp" is 8lp/mm roughly.. I
don't know if this is true or not, but I'll take it for a moment. It means,
regardless of what size you blow things up in, there is no way that 35mm can
compete!! It means the 35mm will drop below the sharpness point, 4 times
faster than the MF6x7, and no matter what, the MF will be sharper (assuming,
glass and film resolution is the same) it will be sharper by the ratio of
the film size difference, in the case of 6x7's about 4.5.
So... how can people say, under 8x10" prints, you won't notice 35mm vs. MF,
when you are talking 4+ times the resolution?? Either I'm missing something
here, my math is whacked, or these pro-35mm people, are lying to me and to
themselves...
I mean if this is the case, ok... now I'm going to ask a strange question..
Assuming my Zuiko lenses are sharper than the ones on the YashicaMat.
(Which I think is true). But since it's a 6x6cm for the YashicaMat, that's
more than 4x the size. So... That means, all else being the same, all the
yashicamat lens needs to be is at least 1/4th the resolution of my Zuiko's,
and when I print them, they will look equally sharp to me?? Is that how the
math works here?? Because if that's the case, then I'm buying me a MF!
