Title: 36 Megapixels vs 6×7 Velvia
Post by: timparkin on December 18, 2014, 08:19:17 pm

I posted a precis of my comparison of medium format film and high end DSLRs on Petapixel

But the full article including some interesting results from Henning Serger about film resolution is here..

Maybe I actually should drag that Fuji 680gx out to play.  Got a few backs for it, a few lenses.  Got the old Jobo in the basement ....

Thanks for sharing.

May I ask what lenses you used to shoot this?

Thank you.

Cheers,
Bernard

I have fun with these sorts of exercises.  I find Portra 160 in 120 to be very close to my IQ260.  Same camera & same lens on my tests...
