Elmar 2.8 is one very nice piece of tool by my opinion. I don’t like to judge lenses by dissolving power, aberration corrections and all other technical things, but by theirs “expression”. This one has character of his own, moody with distinguish “old school” signature. I just want to point out that there are bunch of lenses which can be put in this group of “pat time glass”; compared to Summitar, Summaron and Summilux Mk1, Elmar 2.8 is more all round glass and usable in most situations. Go for it mate!
Some technical info to help you make your mind:
Elmar was constructed as an inverted copy of Zeiss Tessar, simplest and sharpest glass of that era. Number of iris blades enhanced from 3.5 to 2.8 model (if I remember correctly) resulting in almost perfect circle around f 5,6; producing very fine out of focus circular shapes and very fine defocus. Late models of 2.8 are cvolty coated and more resistant to scratches, also with improved color “chewing”. Couple of things you should luck fore:
1 Shape of front and rear glass (coating and glass scratches)
2 Fog and fungus (as with all “old bust__ds “)
3 Tightness of a collapsible barrel lock
4 Try to find rear cap for SuperAngulon, it fits nice and lets elmar to collapse all the way. It is weary handy
Good luck
