I thought the fogging would be at the level of the beautiful 19-blade (!) aperture, and therefore easy to clean - but no: both cells (front and back) are fogged within, which means I have to dismantle the lens completely. In addition it's a nice case of Schneideritis as well ... look at all the dots ...!

Note that these crops are from 43 MP Sony A7RII images (unlike most of my other tests which usually are made with 24 MP FF cameras such as the A7 and the A7II!). Shortcomings of any vintage lens are much more obvious when using the A7RII, especially when it comes to longitudinal CAs ("purple finging").
The Hexanon 3.2/135mm is quite good at f5.6, but a little soft at f3.2. Purple fringing is evident even in the center of the images (not shown here). At f5.6, fringing is gone, and the lateral CAs may easily be corrected using RAWs and e. g. Photoshop.
The S-M-C Takumar 3.5/135mm has sharper corners than many 2.8/135mm lenses including the Leica R 2.8/135mm or the Minolta MC(MD 2.8/135mm [4/4]. The Takumar 3.5/135mm (not shown here) is a bit weaker both at f3.5 as well as at f5.6.
Finally the Carl Zeiss Jena Sonnar in its "electric MC" M42 incarnation: really surprising quality wide open (very little CAs both lateral and longitudinal), and good detail resolution. Surprisingly when stopping down the CAs increase - a phenomenon known from many IT telephoto lenses (e. g. Minolta MD 4.5/300mm IF, Nikkor Ai/AiS 4.5/300mm IF-ED and Canon nFD 2.8/400mm L). Some readers may remember that in earlier thread I was complaining about quality control issues with the CZJ 3.5/135mm Sonnar; this copy however is very good indeed.
More results will follow in a new thread.

Very interesting results. What surprises me a bit, is that in your pictures the CZJ shows less detail @f/5.6 than at f/3.5. I did corner test a while ago, and the corner sharpness increased a bit from f/3.5 to f/5.6. Check here, and scroll half way down for corner comparisons: http://forum.mflenses.com/viewtopic.php?t=83098
CA's seem worse though once stopped down, just like in your comparison.
What also surprises me is the Takumar's corner performance. Although I love this lens, this is even better than I expected.
The Hexanon's corners wide open are a bit worse than I expected. Although it confirms my earlier finding (I had this lens before) that this lens only starts to excel when stopped down. If I remember correctly, the CZJ 135/3.5, Nikkor 135/2.8 and Mamiya SX 135/2.8 were a bit better wide open, even in the center. Which is the reason I got rid of my first example of the Hexanon. Until I ran into some stopped down pictures again, and decided to buy one again. _________________ For Sale:

Found some older test results (center performance, the CZJ is not included though).
At f/3.2 the Hexanon is quite weak:
Look how strong the Mamiya performs wide open.
At f/4 some of the hexanon's competitors seem slightly better, but the differences are now much smaller:
At f/5.6 the Hexanon 135/3.2 is very good, maybe the best of the bunch.
Hexanon's strong suit IMO is stopped down performance and smaller than usual MFD. Stopped down image of Hexanon (crop, I don't remember percentage):

That's one of the Minolta SR lenses I'm still missing in my collection ... did you get it from Japan?

I just re-checked the EXIF data of the Sonnar images, and I found that the f3.5 image (taken at 1/60s) has in fact slightly sharper corners than the f5.6 image (taken at 1/20s). Then I re-took both images and found that you are right: Now the f5.6 images were slightly sharper (and had more CAs, as before). A third series, focusing at the corner, again was slightly different, now with both images nearly being identical. Obviously when using 43 MP sensors the Sonnar has longitudinal CAs and some visible focus shift when stopping down. Focusing therefore isn't straightforward any more; the focusing point simply isn't defined exactly any more.
When using FF cameras in the 50 MP range (or APS-C cameras with 24 MP) things get really tricky. That's why I usually prefer 24 MP FF cameras when using vintage glass. On the other hand these slow 135mm vintage lenses (as well as several lenses in the 50-100mm range) are suitable for 50 MP sensors if one really works carefully (aperture at f5.6 or f8, and removing the CAs in post processing).

Yep, I was surprised as well. Apart from some initial tests using 24 MP FF cameras I hadn't really used the lens, since I mainly use f2 lenses in the 135mm range (or f2.8 zooms). Many other Takumars and S-M-C Takumars were quite disappointing compared to the corresponding Minoltas - even well known lenses such as the S-M-C 1.4/50mm and the S-M-C 4/150mm, as well as the S-T 3.5/24, 3.5/28 and 3.5/35 didn't outperform the Minolta lenses I was using before. In fact both corner resolution as well as color saturation were inferior.

That was my impression too when I got it - average wide open and really good at f5.6 ... f11 (using 24 MP FF).

You are right, and you can add both the Canon nFD 2.8/135mm as well as the Olympus OM 2.8/135mm to this list. All of them are better at f2.8 than the Hexanon at f3.2. Surprisingly, the Minolta MC/MD 2.8/135mm [4/4] isn't really better than the Hexanon, and so is the Leica R 2.8/135mm (last computation).

Do you have experience with the (tele-)Elmarit 135/4? That lens spikes my curiosity sometimes, as it is quite affordable for a Leica, and generally has good reviews. _________________ For Sale:

Not quite, the first version of the 135mm F 2.8 was a pre-set lens that was available for a short time prior to the upgrade to Auto

Yes, it was mounted on an SR-505 camera, which also turned out to be in quite good condition

The lens scheme of the two lenses is identical, they are both the first SLR 135/2.8 optical scheme, although the lens you showed is the earliest release, or version, of it. |

Hi stevemark!
Do you plan to open this one and clean the haze? If you do, it would be great to see some photographs of the repair on your website.
I have the 150mm f/5.6 version with 19 blades. It is a work of art! It came to me with just a few tiny specs of dust behind the front group. So, I went in from the front and gently blew the dust out with the lens inverted. Then I looked down at the meat hooks that used to be my hands, small tools on the kitchen table, etc., and quickly re-assembled it before breaking something
If you do open it up for cleaning, it would be great to see some photographs of the process.
I love your website and translate/read it often.
Best wishes for a happy new year! _________________ ~Jon |

Yes, I can do that. Not sure whether I'll have time tomorrow or Sat since I have to travel from Switzerland to Italy on early Sun morning, and such adventures are getting increasingly complicated these days.

I would love to, and will help, if you would honor me to do so.
Problem is, I don't speak English, I speak
https://en.wikipedia.org/wiki/Redneck redneck.
Half joking about Redneck.
The wiki description is so horribly bad. Rednecks actually date back to the US civil war with warriors wearing red scarfs(?) (guessing scarf is the best word for international translation).
I think I can use a translator and get close. Personally, I would love to help as long as we are not in too much of a hurry.

Just picked up over a dozen this past month, mostly from lots. Several are junk, but here are the highlights:
Cosinon Auto 55mm f/1.4 - arrived in very nice condition. I really enjoyed the combined bubble and swirling bokeh of the Cosinon 50mm f/1.7, and heard this would do the same.
Super-Takumar 50mm f/1.4 - 8-element version. Second one of these, just couldn't pass it up when I recognized the rear element step.
Canon FL 55mm f/1.2. - Rear doublet suffering some separation. I tried taking it apart and fouled up the helicoid, but at least I know how to take it all apart now. Going to try again on my next days off.
Vivitar Series 1 90mm f2.5 Macro with 1:1 adapter - The lens itself is nearly pristine, the adapter has a small amount of fungus. The listing didn't include the lens mount, so I was pleasantly surprised to find it was Pentax K.
Currently expecting another lot that includes a Vivitar 35mm f/2.8 that looks an awful lot like a re-badged Auto Mamiya/Sekor 35mm F/2.8, and a mystery Super-Takumar that will probably end up being a 35mm f/3.5, but I'm hoping will surprise me.

The zoom has some internal haze, so depending how it looks and performs, I guess I get to disassemble it. I haven't reassembled a zoom in decades. I did disassemble a nice Vivitar zoom and found it has haze between the elements in the rear group, sort of reassembled it and tossed in the junk lens pile
After reading about the zoom here, I grabbed it up in hopes of cleaning the haze. It should keep me off the streets for a few hours, which is best for everyone. _________________ ~Jon |

The MD 4/100mm is an excellent lens, not only at close distances, but also at infinity. In fact it is perfectly sharp wide open over the entire image (24 MP FF). It has even less lateral CAs than e. g. the MD 2.5/100mm [5/5], which certainly isn't a bad lens at all ...

Funny thing is that this lens + camera was already on Marktplaats for two days without anybody bidding. Mamiya is still so underrated.... _________________ For Sale:
