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

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. _________________ For Sale:

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. ðŸ‘🙂 |

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. _________________ UK |

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. _________________ pentaxian |

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.

Super Multi Coated Takumar 135mm f3.5...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. ðŸ‘🙂 |
I bought one of these (the Super-Multi-Coated version) and it had something wrong with it because the images were very blurry. It turned out the second element was improperly seated inside the body (it's easy to see how this could happen if you've ever taken the lens apart and put it back together again).
I doubt it came that way from the factory, but there weren't any marks on the lens, so who knows?
Anyway, after I took out the first two elements, cleaned them, and put them back properly, the performance was excellent, particularly considering how inexpensive these are.
BTW, in case anyone is interested, the tolerances for the second element are extremely tight. If you seat it incorrectly, it will get stuck in place and be very difficult to remove again. I found the best way by far was to turn the body upside down and insert the element up from below. |
