Optics Theory - This forum is aimed towards the TECHNICAL side of photographic OPTICS THEORY. There will be some overlap by camera/manufacturer, but this forum is for the heavy duty tech discussions. This is NOT the place to discuss a specific lens or lens line, do that in the appropriate forum. This is the forum to discuss optics or lenses in general, to learn about the tech behind the lenses and images. IF you have a question about a specific lens, post it in the forum about that type of camera, NOT HERE.

I'm surprised at how well the CV lenses performed, and how poorly the older Leicas did.
In particular the sharpness of the CV 35 Ultron wide-open was much better than the things I'd heard about it lead me to imagine. I was also pleased (but not surprised) at the performance of the PII which has always delighted me, for price it is simply incredible.

I am pretty shocked at how little difference there seems to be between most of the modern lenses in the test, though I do think that under more "real world conditions" differences would reveal themselves over time. I've always found it hard to determine how I feel about a lens after a single outing, but protracted use usually tells a story once you've shot it under a variety of conditions.
No offense to Raid who I think has done a brilliant job, I'm merely musing over the fact that tests can only hope to tell us so much.
One thing the test does tell me is that the difference between B&W films can be much greater than the difference between various lenses, and I'm now more keen than ever to experiment with new films rather than daydream about owning new lenses - definately a good thing!
Hi Bosk,

The testing is not done yet; yesterday and today I shot one roll per lens for four lenses, for images under all type of conditions. If I had the money to dvelop and scan many rolls of film, I would have done this for each lens. With 27 lenses [and 27 36-exp rolls], the total cost would be over $400 [plus the cost of the 27 rolls of film]. One of the best benfits of such tests is maybe to get a useful conversation started here.
