Test of 8 M42 35mm lenses
View previous topic :: View next topic

I'm preparing test of some M42 lenses, I've just finished taking samples and I'm quite surprised:

e.g. Super Takumar 35/2 (PRO version), which seemed to be better than SMC Takumar 35/2 under overcast sky, is way worse under direct sunlight (wide opened).

AF Sigma SA 17-70 (reference) seems to be very good compared to M42 lenses, but it's not very fast (f/4 at 35mm).

whole list:

  • Asahi Super Takumar 35/2 PRO version
  • Asahi Super-Multi-Coated Takumar 35/2
  • Asahi Super-Multi-Coated Takumar 35/3.5
  • Carl Zeiss Jena eMC Flektogon 35/2.4
  • Cosina Cosinon 35/2.8
  • Schneider-Kreuznach Curtagon 35/2.8
  • Schneider-Kreuznach Baby-C (C-Curtagon) 35/2.8
  • Sigma SA 17-70 macro ("35/4")

I tested sharpness and CA, not bokeh (these 35mm lenses are not ideal for macro with the exception of Flektogon, so maybe next time)

I'll upload first set of shots in a few minutes (auto converted RAWs, colors are so and so, but never mind for this test) Smile

First of all...FUN to see these tests. Yeah, they may not be "precision" tests, but it's fun to see real-world subjective tests.

Looks like the Flek is the winner to me.... Very Happy

Results at f/2.8

This is kind of stress test. Under direct sun-light all of these lenses performs much worse than under scattered light. Esp. Super Takumar 35/2 (PRO), Flektogon 35/2.4 and SMC Takumar 35/3.5. These lenses are usable wide-opened in many other situations. Under less stressing light conditions Super Takumar 35/2 PRO is comparable or slightly better than SMC 35/2 and Zeiss Flektogon is even better than both of them.

Cosinon is suprisingly good at the center.

Thanks for your hard work doing this, I tried it once. Wink The only lenses I have to compare with your test are the MC Flek and a Super-Tak 3.5/35. I'd have liked to see a MIR-24M in the mix, but I think the Flek is slightly better.

Results at f/11

Many Takumars (not only 35mm) are best at f/5.6-f/8. Results from Flektogon are almost identical from f/5.0 to f/11. But 35mm lenses from Schneider Kreuznach are best at f/9-f11, esp. their border sharpness.

Here is one bonus:

50 years old Auto Takumar 35/2.3. I sold this lens some time ago, and it was a mistake. It was very poor wide-opened, but it's central resolution and ZERO CA was just stunning. Here is one old shot at f/7.1:



and pictures of all lenses:

Asahi Auto Takumar 35/2.3




Asahi Super Takumar 35/2.0 PRO




Asahi SMC Takumar 35/2.0




Asahi SMC Takumar 35/3.5




Carl Zeiss Jena eMC Flektogon 35/2.4




Cosina Cosinon 35/2.8

(this one picture was not taken by me:)

Excellent test! Thanks.

BTW, isn't it impressive how well the Sigma 17-70 performs?


PostPosted: Sun Jul 27, 2008 6:48 pm    Post subject: Reply with quote

I was impressed too. It's CA is very significant at 17mm, but very low at 35mm. The only problem is f/4 at 35mm. Flektogon and some of the Takumars would be very similar at f/4...

This is a lot of work! Many thanks for sharing!

Here are Vivitar 35/1.9 results. I unfortunately used f/8 instead of f5.6, but it doesn't change anything - Vivitar is best at f/7.1 and both f/5.6 and f/8 are sligtly worse, so results would be almost identical.

Excelent job. Thanks you

About Schneider lens, don't forget that it's a lens from 1970/71 (N10.xxx.xxx). I beleave that in theis moment the photographs used 35 mm and 50 mm lens - both - and the 35 mm especially for great DOF, may be this circumstance did that Schneiders designers choosed F/11 or lower as better diaphragms. Perhaps the coated of this era wasn't so good.

Rino.

I owned three 35mm lenses in m42 mount, and I sold them all, because none was better than 18-55 kit lens.
1) a cosmetically good mamiya sekor sx 35 /2.8, whose rear I had to grind to sit on the m42-eos adaptor. Bad performer, even stopped down.
2) a minty super-tak 35/3.5. Nearly as bad as the mamiya, worse than kit lens even stopped down.
3) a battered mir 37/2.8. Terrible wide open, and very bad closed down.

Since I have read favourable reviews on the three lenses mentioned, I assume they were all lemons. But be cautious. Copy variation is not a problem only of soviet lenses.
I got rid of them, along with a pentacon 30/3.5 that was much better, with nice saturated colors from wide open. I just sold it because I did not find it special at the time, but it is one fine lens.
