Hi All My first post. Been a Leica M system shooter for about 5 years. I’ve been in the market for a 28mm Summicron and have found one that is ~5 years old being sold by and older gentlemen. Visibly, no scratches, no dents on the tube, and overall seems to be in order and results from tests are good. However, when I remarked that he’d obviously taken care of it he told me he cleaned all his lenses generally every fortnight with fluid and lens tissue (?!) personally I avoid cleaning and always use UVs to protect my lenses and fortunalty never neeed to clean a rear element. However, this lens as good as it looks has been cleaned very regularly whether it needed it or not it seems. The lens certainly reflects green so I’m confident in the UV anti glare coating. Could his cleaning and or the fluid have in anyway weakened the balsam? How strong is the lens cement against pressure or fluid? I’m keen on buying it but I’d be concerned if he’d in anyway weakened the construction through pressure on the lens or with fluid (Giottos or Inca I believe). Otherwise, if the lens was in a shop and I was told it was new, I’d believe it.

Hi all, I've recently upgraded from a 28mm Elmarit f/2.8 (pre-ASPH) to the 28mm Summicron f/2 ASPH (used) and I received the lens yesterday. However, it seems to me that the Summicron is not focussing at infinity when I'm trying to: I'm noticing that faraway objects are out of focus, ever so slightly. At first I thought it was due to the lens being slightly softer wide open, but I stopped it down to f/4, all to no avail. I'd like to know if the lens is damaged so I can return it in time. Here's a screenshot comparing the two. I've also uploaded the raw files here. I'm new to the M system and I'm unsure what to do: and given this is a very large investment in a lens, I'd like to be sure that the lens is working as expected. Thank you.
