I am always struck by the ease with which some people can pronounce a lens 'signature' as being Vintage or Modern from looking at an image. It would seem an impossible task, given the sheer number of variables (film/Developer/light conditions/scanning/contrast etc) involved that would affect the 'look'.
I am assuming there is more to it than just differences contrast, sharpness, and flare. Perhaps it is easier to see/show than describe !
I own several 50s and 35s, but have never done any formal testing to try and extract a certain look. Wonder if anyone can post 2 (or more) images and point out the specific look in an A/B comparison ? Something that would make it clearer what a Vintage vs a Modern look is ?
I have always asked the same, even protested and of course ignored within the same technical thread, as I suppose it will happen here again, when a small image is shown or celebrated as depicting a great lens.
I have proposed a different method for giving a sense of the lens: show the full frame image, and afterwards a little crop, enlarged to the size of the former depicted full frame image.
Unfortunately, it seems to me that so far no one answered the challenge but me only in a test of an Iskra camera. The big enlargement of the small crop looks much less elegant - perhaps this being the reason for the people reluctance. Of course, 99% of us may have not read my rant, nor this one, but those a little bit knowledgeable about optics know very well what they are doing at the technical lens threads.
B'cause Mom, if there is something more forgiving by far and large than Tri-X, it is the computer screen. And besides the computer screen there is the photoshop washing machine, which makes wonders acccording to the knowledge of the operator.
Another reason why lens tests are never shown this way, not to speak about small crops of an image shot at widest apertures, seems to me to be that many folks rather love to abuse technical threads about lenses for picture gallery purposes. Well we all are just humans.
What's the technical value of depicting an astonishing composed image of a lens as proof of its technical qualities ? Absolute zero. The better the aesthetics the more it distracts from what we are supposed to see. Even if the images are shown at widest aperture. They may speak on behalf of the compositional qualities of the photographer, but not at the propper thread. Notice that I mention the images in plural, since most often we are presented not with a single indulgence, but with a series. Too much ego around.
If all these weren't enough, there is in fact a good source for lots of technical excif data and it is flickr. What a paradox that a site supposed to be for picture gallery is by far a great source of technical info, while we here, that talk so much about techs, and are held as too much tech speaking, and even some of us have repeatedly expressed their opinion that RFF should limit itself to tech talk, tik tak, rf tech talk, have such poor a record in lens performance info.

Post Mortum:
For a stunning effect and example of many things I have said here, you can go to this flickr image:
http://www.flickr.com/photos/ysjjhfox/4473359889/in/pool-1084614@N23
and start to enlarge at the good manners enabled by the photographer.
Then go to the exif data and start learning more things about the image.
