Summilux 35 f14 ASPH filter thread

Hi Alexandre,
I used a tiny bit of olive oil (!)to lubricate the tread of the filter.
Try it, it works great. No sense buying an expensive lubricant. Olive oil is a natural product without additives. I cannot believe it can damage anyting.
What filter do you use?

Another lubricant to consider is Vaseline. Leica recommends the very smallest}}}} amount be smeared on the bayonet fitting (either camera body or lens) If you can see it...you've put too much on! This will reduce wear from the frequent changing of lenses. I was thinking that perhaps the same could be used on the filter threads. Maybe they were just dirty?

Hi Colin,
My filter was brand new, however any metal part with thread will benefit from a tiny amount of lubricant as long as you keep it clean.
Vaseline should work fine as well since it is also a natural product
