Slight focus resistance at 1–2m on my Summicron 50 V5 — normal?

[Endzeit]

Hey everyone,

I’ve got a Summicron-M 50mm V5 (serial 399xxxx), and I’ve noticed a point of extra resistance when focusing around 1–2 meters. It’s smooth, silent, and honestly only noticeable if I really pay attention — otherwise it feels fine.

Just wondering if this is normal behavior for the V5, or if it might be a hint for a deeper problem that could get worse over time. I could still return the lens if Im unhappy. Price was ok (much less than new anyway).

Thanks in advance for any thoughts!

It's hard to think of that as normal behavior for a Leica product, but it is not unkown, either; certainly not for a used lens. I suspect there may be a little dirt in the helicoid. So a cleaning and lube may take care of it.
