which is a better lens?
Out of the seven I-26/I-61 lenses I have or have had, all 7 needed a re-lube. They're old and it's unreasonable to expect grease to last that long, especially russian grease! I have only one with noticeable "slop", that being the newest of the bunch. In terms of using grease to make up for machining deficiencies, it's worth noting that a certain german manufacturer of high standing did the same on their lenses too.I have not used my I-61 l/d in quite some time, but it did give more contrast and perceived sharpness than my J-8. On the other hand, my I-61 l/d was very stiff when I first got it and, after I lubricated it, it had a considerable amount of play in it. I suspect that the factory depended on the grease to make up for poor machining tolerances.
