Hi, I've just bought a Petri Color 35 that (amongst other problems) has a very stiff focussing wheel to rack the lens in and out. Can anyone advise what lubricant, if any, should be applied to the helical thread of the focussing mechanism? On an SLR I'd use LM grease, but the helix is a very fine multi-start and I have a feeling that grease would actually give more drag rather than less. Equally, I'm not comfortable about oil, as who's to say where it will go. Secondly, the focussing seems to lack the infinity click stop. Any info on where the mechanism for this is to be found would be much appreciated. The symptoms of both the above faults seem to indicate congealed lubrication. Thanks in anticipation, Steve |
