I don't think I'd have ever guessed the cable release!

Nice work Clarky

As others have mentioned there's nothing between them in terms of image quality, so if you can live with the slower operation then you won't lose out with an M50.

What hasn't been mentioned (yet it's something I find important) is that the M series lenses - rightly or wrongly - just give the impression of higher quality build than the A series ones. They're more compact, less plasticky and just feel right somehow.

I'd go along with that too

It's a quote from the side of the barrel where it says "Sigma Tele-Macro Converter 2x 1:1". I've not even bothered putting it on a camera due to the large fungus infestation to be honest, it's a spares or repair job for someone who needs one cheap and doesn't mind wielding a screwdriver...

It's a lot longer than a regular TC and I'd imagine the offset works in the same way as extension tubes. Don't forget this is pre-PK/A so we're talking 70's tech here.

I reckon #1's a watermelon seed and #6 is the little dot on the side of an M series lens to help you line it up. No idea about #2-4 though!

So what did you use to get this close? Looks like more than 1:1 to me...

Both M42 CZJ Tessars now sold - knew I'd priced them too cheap!

Suprised the Pentacon 135 is still there after nearly a day though, I was expecting to get my hand snapped off for £30...

Too many lenses, too little time!

I'll be doing some more auctions next week with some pretty shiny things; in the meantime though I've got far too many untested lenses which will never get looked at, hence I've put a load of them on eBay with reasonable Buy-It-Now prices (in an attempt to catch up a bit).

You can find them here (if they're still for sale by the time you read this!) and this is what's listed:

Cosina Cosinon-W MC 28mm f/2.8 (aperture locks when focussed to infinity) £8

Plus another dozen or so assorted Minolta MD / Olympus OM / Praktica PB mount lenses. And a cased set of supplementary screw-in wide/tele lenses for video cameras (37mm and 46mm threads with included adapter) which are from Sigma and look to be unused (£14.50).

The above sales are all live now and run for 10 days, the auctions (99p start / no reserve) start on Monday evening and will run for 7 days. There are a couple of Pentax related auctions amongst them; a Centon K100 (Pentax K1000 clone) outfit boxed with lens (50/1.7) & accessories and practically as-new, and a mint / cased version of the M42 Pentacon 135mm f/2.8 Preset with original original hood and caps. Plus cameras from Olympus and Rollei and a super-rare Haiou-64 lens for Minolta MD.

It's not just Nikonians that do it: clicky

A little more tasteful methinks

Can I put my name down as first on the list for the Voigtlander once you get bored of it please?

What's that? A 60-250 for a tenner? Don't mind if I do!
