Well, nothing new there then, but what I mean is , On a serious note, I need some help. I've hopefully got an upcoming project which requires my using film. Now, recently I've acquired a Praktica SLR (an old MTL3) with a few lenses. The lenses are where I need the advice, just in general what people's opinions are and what they are more suited to. Lens one : (Even I understand this one) - Pentacon auto 1.8/50, standard lens - no problem. Lenses 2 & 3 - can't find a brand name, front reads; "AUTO P PALAR 1:2.8 f=135mm No. 258311" other is "CARL ZEISS JENA DDR MC 1:3.5 f=135" - now, evein I've heard of Carl Zeiss, but the coating on this lens has a small scratch in it. Now, please, in simple terms, what's the difference? Cheers Gang!!! (",)
