Thanks for that mythguy9 (are there really 8 others :) & Paleo Pete. Actually I have lens separation I think, so what I'm seeing is tiny air bubbles in melted glue. I got the impression I can't remedy this myself, so I'll leave things be. I've just bought a Ricoh Rikenon P 70-210mm f3.9 Macro Zoom - reckon I'll keep the better of the two.
This old Pentax glass is a bit obsessive :)

Well good news folks - the lens takes great photos, no lens creep, smoooth & sharp!
Just got to hone my manual skills!
So pleased I switched to Pentax - all this lovely old glass with built in shake reduction - perfect for amateurs like me!
Thanks for all your help!

Well that's useful info - and there was I about to rush out & get a filter for the 50mm f1.7 - would prevent direct physical damage to the optics through airborn pollutants (eg. fat droplets, acrid rain) though?

I don't think it's any of those things either - there are probably hundreds of them absolutely tiny - imagine the tiniest fat droplets. Best description I can manage, sorry! Anyway the proof will be in the photos - just thought someone must have seen this before.
Thanks somuch for the response though :)

Just bought my 1st Pentax, a K100D & have been having a grand time test driving the kit lens & a fab SMC-M 50mm f1.7. I've just got a SMC-M 80-200mm f4.5 too. At 1st glance in good condition but the front optic (no uv filter) has what appears to be tiny bubbles in/on it, on the inaccessible side. I can only see them in a certain position & am unsure if they are part of the glass itself. Anyone shed any light on this pls?
