My better half ordered the 77er and 82er, have briefly tested today. The 82 turns quite stiff, with a little oil was not the better. The kleinre turns significantly better. The polarization itself is 1A. Focus: In '82 I have a minimal blur that does not exist in the peripheral region is without a filter. In '77, I saw no difference. (May also be related to the lenses used?) Threaded bit fiddly, you sit thinks it, then goes still a little, and one he hopes does not fall down suddenly. If altenm '67 that went better, but may also be due to the lenses. Are, however, quality of Canon, whose thread should already be OK.
