Most lenses have out of focus characteristics that change quite a bit when you compare wide-open to one stop-down. You'll have to see what you like personally as it relates to your photography. Two different lenses at f/2, with one of them being a faster lens, will be two different animals if blurry backgrounds are a big part of your images.

Well the -cron is gone now, so no comparing possible anymore.

And the -lux is in the clinic and hopefully back soon with a new lease of life.

If you really, really care for getting the maximum sharpness and micro-contrast, you should shoot medium format.

Don't lose your time with 35mm if ultimate sharpness and resolution is what you want. Even 6x4.5 will blow the socks off 35mm in those parameters.

Shoot a leica rangefinder if you want speed of operation, compactness and light weight.

That used to be true, but 35mm T-Max 100 semistand developed in Pyrocat-HD is very nearly what I'd expect from MF.

I don't find this to be. TMX in 35mm is amazing, that's for sure.

The microcontrast and sharpness approach a good many MF systems. At 8x10 print size, I doubt you can tell the difference reliably, maybe even at 11x14. It all depends on print size and viewing distance.

So, sure, if you compare it to a 'Blad negative enlarged to wall size, you'll see the difference. But in real world viewing situations, the difference is very small if you create the negative properly.

I didn't believe it either until I shot some 35mm TMX and semistand developed it in Pyrocat-HDC. The results were jaw dropping - like nothing I've ever seen from a small negative like this in the past.

In that case, you should try have fun with 120 .
Resized of course for Photrio.
Just don't complain when you are trying to use the grain magnifier under the enlarger.

Maybe we can go back to topic.

Still not back. Will see how it works on my M bodies..

Haha - it's already a pain with 35mm. I can't wait to try it with my 120 and 4x5 stock in the freezer waiting to be used.

Nice image, BTW.

I will say that TMX and TMY definitely have their own look. TMX doesn't look anything like Plus-X or Agfapan 100, and TMY definitely doesn't look like Tri-X.

Arent you a Mamiya expert, what do you think about the "Press" models

I think that is a reasonable question, but probably deserves to be in another thread - in the medium format sub-forum.
And while I'm quite familiar with lots in the Mamiya MF ecosystem, the Press cameras aren't among those I have worked with.

How do you mean that? Microtonal?

...that's because you have not tried Tmax 100 or Acros 100 on Medium Format...

I disagree. Even at 8x10" (OPTICAL PRINT, not silly digital prints) you can see the difference. Even moreso using color film (and real optical prints).

I can easily identify the 8x10" prints i made with my 6x7 gear versus 8x10" made with 35mm gear, of which I have many.

I love my 35mm cameras and indeed TMX or Delta 100 or Acros gives much better results than conventional films, but MF still looks better and sharper, mainly because the combined MTF (modulation transfer function) of the system(*) is far higher.

(*) System = lens + film + enlarger lens

Now, if we are going to compare doing average quality flatbed scanning, my medium format negatives, scanned by a crappy Epson flatbed, are inferior to 35mm negatives scanned using a DSLR and macro lens. But that's not fault of the format!

I thought MF lenses are slower than 35mm lenses
