My coll. screw mount is from the fist production & selling year, 1953 (meter), and has the s/n 1.093.400, and my coll. M mount is from the first M mount production & selling year, 1954 (feet), and has the s/n 1.167.402. The visiual difference between both lenses is, that the M mount Summicron's coating gives a cold-grey impression (the glass is very clear !), while the screw mount Summicron is more dark blue (clear glass, also). Additionally, the M mount front lens reflects the light more strong (in a way, as if you look in some kind of mirror), while the reflection in the screw mount's front lens is less strong (has been in a board for 20 years). My dealer sold the Summicron complete with a IIIf (red dial, auto release), and the nice number 6 89089 (1954) to me on $ 750. By the way (1), what does D/A mean [context: IIIf red dial D/A] ? I specially like, that both the lenses show a somehow cold spectrum, but I wouldn't know their behavior with color negative material - since I never use it [ I "hate", that labs interprete my pix by their filter selection ! ]. The shaprness (in slides) is very near to the actual Summicron, but the unsharp areas give a somehow more pleasant impression, and the contrast is a little lower (in my perception). By the way (2), how do you get the LHS or LHSA newsletters ? Thanks in advance for your answers, Regards, Alf
