Elmar 50/3,5 on Canon

Putting a 60 years old lens on digital SLR camera I did for Elmar 50/3,5 with close up magnification 1/3 ratio. As shown in the pictures, inconvenient and unnecessary internal light reflections were prevented by laying special anti-reflect cloth with fine black hair transplantation, this kind of trifle modification is an indispensable process especially for old lenses with primitive lens coating. This smallest and very thin pancake lens is enough to cover almost of subjects.
As for lack of color contrast because of single coating, some image processing by software Photoshop would compensate enough following the usual manner done when Elmar 65mm/3,5 macro lens had been used.
Most of lenses manufactured by most of production companies recently are designed with computerized solutions, so the definitions are almost the same. Utilizing old designed lenses is worth doing among them, so I think, there may be some possibility to obtain photos of different representations?
