Septons are prone separation. I waited for sometime to get clean copy without separation. After owning all the other three 50/1.9 and 50/2.0 in the Retina mount, I can say this is the best corrected lens among all the four lenses. This is a lens I think worth to buy for those who like the DKL lenses. Contrast is first class among the 50-55mm F1.9-F2.0 lenses I have tried produced in the same period.

Apart from exposure adjustment, no other edit is done to the photos. I applied the same profile to all the photos below.

It's a wonderful lens for portraits also, excellent built, probably a pain to repair , even though I cannot imagine a septon with stiff focus ,maybe neither oily blades ,i might be wrong though.

My copy has stiff focus but no oily blades. I leave it as it as I use helicoid to do the focusing.

So you're using a m42 helical to Sony and a dkl -m42? What thickness is the hellicoid? I might need this option to use the dynarex 135mm as it's mfd pretty high around 4m if I remember correctly, but it gives nice tones though. Never tried it on portraits because of that long mfd and I wonder what should I expect from it

Yes. I use Yeenon DLK to M42 adapter +Yeenon M42-NEX helicoid. When the helicoid is retracted, it has the same thickness as an ordinary M42-NEX adapter.

I expect the Dynarex 135mm on portrait distance should perfom well.

Really nice rendering, thanks for showing.

Definitely get some sort of extension capability if you're going to use the Super Dynarex 135. It's a good lens, and it should work well for portraits, but that 4m minimum focus is completely unacceptable.

I also use a DKL-M42 adapter attached to an M42-FX adapter with a helicoid. With the helicoid fully extended the minimum focus distance drops down to just under 1m, which is perfectly sane and usable.

Calvin your images look very neat and pretty surreal colourwise, taking into account the age of the lens. I suggest, the puzzling effect comes from a combination of the "vintage" bokeh and of the "clinically" modern colour and sharpness. Such a mix is amazing and almost disturbing! Thanks for sharing.

Like almost teles of the past, the minimun focus of 4 m were reduced with the "portrait" filter, focused from 2 to 4 m (near 0,25 diop).
With it, the close focus and wide open had good center colours and sharpness with very soft corners.

The septon had the same formula than Planar 80/2,8 made for Hasselblad 500 line.

When Voigtlander made the Icarex (under Zeiss ) changed the septon with the newer and better Zeiss Ultron 50/1,8 designed and made by Voigtlander

Thank you very much! This is exactly what i thought. The advancement of camera technology enable us to further push the potential of vintage lenses.

Yes. They share a very similar design.

I have the Ultron too. Both are first class lens of its time.

In my experience, the Zeiss Ultron 50/1,8 is (with the Kern macro switar 50/1,9 for Alpa) one of the very best 50 mm lenses .

It's rendering wide open is close to my Sony 50/1,2 GM.

I would like to have the F1.9 version too but it is out of my budget. The switar 1.8 does have more vintage feel which I like. May be one day i will get a F1.9 if i have some spare luck.

BTW, I am testing a copy of Leica R 50/1.4 E60 version. It seems it has some character comparable to the lenses above.

Have you tested the Septon 50 on the GFX? I'd be interested in that result.

Bokeh of #6 is splendid!

An old italian member, Orio, made a complete review of the septon, years ago.

Very nice work in some ítems of the lens.

I can't find it now.

Not yet. I have to finish the testes the Leica R lenses before moving to other lenses. If you are asking about the coverage, then it should be no problem according to the data from spiral https://spiral-m42.blogspot.com/p/list-of-35mm-lenses-that-do-not.html .
