Voigtländer 12mm 5.6 for L39 screw-mount. Came with it's (enormous) original finder... and a Bessa L was attached to it too Wink

I've had the 15mm before but was a bit disappointed by it's performance on the Sony. It's really good on film, but then my only L39 camera was a really beat up Fed2 so it didn't see much use.

The 12mm is not perfect either, it has horrendous vignetting but it's insane angle of view makes up for the extra post-processing time.

Unfortunately I think this might be too wide to try the PCX filter trick to improve performance

Another one for my little komine collection. Very nice actually, minty, boxed.

I'm not a Canon collector but the price for this lens on a local auction site was too good to let pass.

Super Multi Coated Takumar 135mm f3.5

Had a quick comparison with my lighter Pentax M 135mm f3.5 last night and the Pentax seemed sharper, but with more aberrations. Need to do a proper battle as I only want to keep one.

This will be an interesting one- an f2.9 Pentac (not written on the lens) with a clearly custom housing job, and what looks like an M42-C(?) adapter. It was left in a Yashica 200mm box, hence the auction title:








I'm not sure if the Pentac threads came in silver, or if they were sprayed with the barrel itself:



And I'm wondering where the adjustable aperture is, or if it was even with this 'version' that wasn't labelled Pentac. Maybe used for a projection purpose, then adapted to a camera? We will see.

And on second thoughts, the box might be worth the price of admission too - 200mm f/4:

I find the Takumar actually a surprisingly good lens. Check out a test I did earlier: http://forum.mflenses.com/leica-elmar-135mm-f-4-compared-with-others-t83362.html

At infinity it’s also pretty good. And build quality is 10/10.

Interesting find. There is a topic: http://forum.mflenses.com/dallmeyer-london-pentac-f-29-patent--4-1-4inch-t46036.html Good thing you knew what you were looking at .

Didn't include the shot which shows the aperture labelled sorry- otherwise you're just looking at an 8" lens:

Mine isn't great. Selling it. But the Pentax is riddled with CA, so will replace that with something else. Hearing yours is so good makes me want to try another copy of the Takumar. 👍🙂

W-komura 35mm 2.5 Just a bit hazy with bright light shining through, not visible otherwise

SMC Pentax-A Zoom 35-210mm 1:3.5-4.5 Not for sale very often so I snapped it up. A lot of fungus somewhere behind the aperture. Hopefully I can get to it just unscrewing the rear element so I don't mess up any of the aperture mechanics.

Typo on the 35mm f2.5- although a 25mm f2.5 of that vintage would be pretty interesting!

I didn't even know Pentax participated in that class of 35-200/210.

It is interesting, we also got a 35-210mm f3.5-4.2 Adaptall-2 lens.

Were these made concurrently with the third party 28-200/210 options? If so, why didn't they try for a wider zoom range?

I do already know the answer in part- the size, rather than optical difficulty, although 28 is fairly different to 35. I've read articles from Ellis Betensky when he still worked at Vivitar detailing 28-200 lenses at the start of the 1980s. And one of Tamron's anniversary pages detailing their superzoom history noted size as being a key barrier to introducing a 28-200. Their first version was alot smaller than the Samyang 28-200, for instance, and it wasn't just a matter of smaller aperture.

I would be very curious to know how the aperture of this Pentax declines throughout the zoom range. I think a piece comparing all the 35-200/210 would be valuable.

That could be the problem. Probably combined with IQ standards. The SMC Pentax-A Zoom 28-135mm 1:4 is the heaviest zoom of the A series even though there being this 35-210 and the 70-210mm 1:4. The 35-105 3.5 weighs more than 200 grams less and has better IQ. Quality over range. It will first have to be cleaned for any decent comparison. Contrast is taking a hit from the fungus and metering isn't very accurate.

Nice.

What are the mount rotation numbers "7", "8" etc? Are they an indication for maximum allowable shift (in mm) without vignetting when rotated against those markings?

Congrats NikonD! Looks like fun.

How's that FTZ adapter? And is that a custom bottom plate -- I could use similar for A7RII with LM-EA7? Thanks!

The numbers are a mystery to me, I have yet to find out the meaning...

FTZ is nice, works as intended. Bottom plate is from aliexpress, I use it as an additional grip for my pinky finger (I have big hands)

I'm actually on the wrong forum then with this lens 🤔

Also bought a Petri 28mm f/2 (Cosinon?). First impressions are good.

Bit of a risk, and was an auction listed under Camera Lenses. Description said

Quote:
Belonged to my late Grandad and selling on behalf of my Grandmother


Not been tested


There are some marks and rubs to the side of the Lenses


All glass on the Lenses do have tiny marks and flecks of dust- I have not attempted to clean







If I get lucky with this, it would be very nice. Otherwise I can still break even easily.

These are all thumbnails, I tried posting it in one row but it's displayed as an awkward single column. Oh well- click to get full resolution.

We have:

Tamron Adaptall-2 60-300mm f3.8-5.4
Tamron Adaptall-2 28-70mm f3.5-4.5
Sigma Super-Wide II 24mm f/2.8 (FD Mount)
Helios 44-2 58mm f/2 (M42)
Tokina RMC 300mm f5.6 (MD mount?)
2x Adaptall-2 Nikon F mount AI adapters
All matching front caps (aside from Helios)
62mm screw in hood for the Tamron

I also keep landing these quality enlarger lenses for £10. This was listed under wrong category though ('SLR Cameras'). I didn't realise but the Komuranon E and S versions are different. I have the former so it will be interesting to compare.

I got this lens with Sigma mc-11. Very nice results on Sony a73. I even like it slightLy better than Nikon 105/1.4.

Good catch, most of those are worth the price of the lot alone
