Lens performance

Three old lenses were tested on Canon 10D Digital body in the condition of close up under day-lighting, Leitz ELMAR 50/3,5, GN Nikkor 45/2,8 and MINOLTA MD Rokkor Macro 50/3,5, with the subject of Morning Glory. All of the lenses were well designed to obtain a good picture promptly as a conclusion and the modified Elmar 50/3,5 had some advantage in convenience, originally sinkable barrel designing had some priority in case of close up to 1/3 magnification, in ordinal use from 1m to infinity barrel is set at the most posterior position. So, an ancient manufactured small triplet with single coating lens is the most useful one as a pancake lens, probably the degree of protrusion of barrel with 17mm from the lens flange should be the least in the world trying also overlooking and comparing another recent productions. The convenience of portability that SLR(Single Lens with Reflector) body has some tendency to lose,  would compensate the disadvantage in bulk.

The lowest picture taken by Lumix DMFC-FX60 compact one as a control provides good enough resolution as a recording purpose, but I cannot prohibit to say that there exists apparent differences in picture quality if compared with single focus length lenses in spite of the age difference between the designing, the picturesque like with pasting method. Of course, zooming lens  designing and the difference of imaging area might be some good reason for the unignorable phenomena.

Basically, I don't want destroy any old art like this Elmar 50mm standard lens produced over a half century ago, but it has a miserable story to have been dropped down with some L-body by accident, not myself but some geriatric friend and once thrown away to a trash and I had picked up the poor one for long time of period with front flange distorted miserably. I happened to come up with imagination to survive it in this digital photography generation by modifying the mounting construction, I wanna say like this if the excuse is allowed.
As a matter of fact, this Elmar 50mm lens survived now like a phoenix now!
