Industar 61 L/Z 50mm f2.8 cleaning

fccwpe · 01-27-2012, 03:21 PM

I just received an Industar 61 L/Z 50mm and have noticed that the aperture blades have quite a bit of oil on them. After scouring through this forum and all over the internet for any info about disassemby/reassembly I have come up empty handed.

Does anyone have any experience with the Industar 61 L/Z?

Thanks!

If I'm not mistaken, this lens is with a preset aperture, which means it has oily blades by design. Even if you open it up and clean the blades, you win nothing, but then you may ruin it. If everything else is OK, I suggest you to keep it as it is.

What he said...a little oil (a mere smear) is the norm with many pre-set and manual aperture lenses.
