I have been on the light table for a few hours, going through my old slides and have to conclude, that in my opinion after using many of the lenses for this system, there is one that I feel is the sharpest. It is the 75mm SCM Takumar f/4.5.
One can see amazing detail in the scene. In one shot with distant houses in a valley below, backed by terraced vineyards, one could count the tiles on the roofs.

I need some other opinions on what you feel is the sharpest because I have not shot all the lenses.

nice info, I've been considering adding only 67 lenses to my 645N in case I decide to get a 67 one day. Looks like the 75mm 67 is a better option for that than the 645 75mm.

There is an interesting rundown on the 67 lenses here:

The beauty of the 6x7 system is that no matter which lens you use, your poster size print will be just fine and blow any 35mm or digital enlargement out of the water.

I found the Tak 75/4.5 to be spectacularly sharp as well. It's only problem is that it is rather more prone to flare than the other 67 lenses that I have.

I don't have any complaints about any 67 lens I own but I am thinking the SMC 67 165mm f2.8 is extremely sharp. There is a section on 67 lenses over at photo.net

I agree, my 165mm f/2.8 is sharp to the corners wide open. stopped down to f/4 it's amazing. A great lens.
