IWC Doppel Posted January 25, 2012 Share #61 Â Posted January 25, 2012 Advertisement (gone after registration) Just for the record whilst at Leica today I asked one of the guys about lens cleaning (he was inspecting a marked lens) and he said less is more, he recommneds blowing and lens paper only if required. Stating that most overclean and wear away coatings over time. Â I guess coatings and opinions vary ! Â I think being careful makes sense Link to post Share on other sites More sharing options...

mirekti Posted June 5, 2013 Share #62 Â Posted June 5, 2013 Can someone confirm that Zeiss pre-moistened wipes that contain Isopropyl are not harmful for front element coatings? I have bunch of them and plan on using them on 35 lux fle and 75 cron. If not, what liquid you would recommend me, I didn't see Leica recommends anything I only found a cloth.

Â I have been using them and the Zeiss fluid in spray bottles for 30 years with no noticeable deterioration. However they are not prefect and can leave a small amount of smearing. For my modern lenses with super hard coating, I then polish with a microfibre cloth (3M Magic Mirror Cloths bought from the SuperMarket - 1/10th the price of lens cloths and they work better). For older lenses with fragile coatings, I huff on them and then use a Pec Pad dry wipe for the final polish. Â You do need to wash the micro fibre cloths frequently in the washing machine but make sure you use a liquid or powder without fabric softener, as the cloth will then smear.

Ecar Posted June 6, 2013 Share #66 Â Posted June 6, 2013 Possibly slightly OT, but am curious as to how others clean their lens barrels. More specifically: I have a bunch of old lenses, which markings have become yellowish. Now, I appreciate that white paint suffers from degradation over time, but I'm pretty sure that finger grease is a significant factor (remember that once-in-a-lifetime picture opportunity that presented itself while you were eating your burger?). I have tried to use a damp soft cloth, to little avail. Any other suggestions that would not risk removing the paint altogether? Link to post Share on other sites More sharing options...
Guest Posted June 6, 2013 Share #67 Â Posted June 6, 2013 Advertisement (gone after registration) Years ago Leica used to say "don't clean your lenses,keep them clean".When I buy a new lens I always fit a Leica uv filter after making sure the front element is spotless.That way I just clean the filter and have the added protection for the front element.Never had a problem and at the price of M glass will continue to do it.Not everyone will agree and lots of valid reasons not to do it ,but unless I hear "don't worry about your Noctilux, I will buy you a new one if you damage the front element" I will stick with this method.

Â Starting with seeing the problems caused by the UV/IR filters on the M8, I came to realise that digital cameras are far more susceptible to spurious/ghost images and flare than film. I believe this is due to two factors. The surface of the sensor is far more reflective than film and secondly, the surface is much more plane (flat). I have quite a few images taken on the M8, with horrible pink circles in them. Indoors is very difficult, if there are wall lights, where ghosting if you have a filter mounted, is close to impossible to avoid. So with digital, unless I am doing something special, I try to avoid mounting filters. Â Wilson Link to post Share on other sites More sharing options...
Guest Posted June 7, 2013 Share #69 Â Posted June 7, 2013 Hello Wilson I have had the odd problem with filters and do occasionally take them off. I tend to keep them on most of the time as protection mainly due to the eye watering cost of replacement.Having said that filters branded Leica are not cheap.I like to remind myself from time to time that I own this stuff to give me pleasure. Hope you are keeping well. Brian Link to post Share on other sites More sharing options...
