Another job lot, all M42 lenses:
Pentacon 50mm f1.8 - a couple of very small fungus specks inside, nothing that effects results
Helios 44-2 58mm f2 - Iris fault, a couple of blades out of position, otherwise OK
Cosinon 55mm f2.8 - slightly hazy but very good cosmetically and gives OK results. This is the one with the weird "turn both ways" aperture ring I had once before, but in MUCH better condition.
Palar Auto Wide 35mm f2.8 - slightly gritty focusing but otherwise pretty good
Domiplan 50mm f2.8 - VERY nice condition, think it's the best I've seen since I started selling lenses.
Prinzflex 35mm f2.8 - won't focus to infinity for some reason.
The lot cost £41 including postage, I expect to make a modest profit - would have been a lot less modest if the Helios was better, of course!
And I found another Sigma DC 55-200mm 4-5.6 on a charity web site for £26.45 including P&P, the last one I had gave very good results:

Should get it some time next week.
Also bought a Belkin gigabit network switch to replace my existing one which is overheating, £12.97 including postage.
