I just won a Sigmatel 135/1.8 fast telephoto

I was surprised to get this fast 135mm F/1.8 telephoto (Click here to see on Ebay) for a decent price, as I thought it would fetch a much higher price (it's offered for sale here for $525). This lens was manufactured by Sigma and used the short-lived YS interchangeable mount developped by Sigma to compete with the Tamron Adaptall system. It comes with the M42 mount and a cheap M42 doubler.

This lens was also sold under the Spiratone, Soligor and Porst brands. It is a scaled up copy of a 135mm Zeiss Sonnar. A very interesting lens. Here is the optical diagram from Pete Ganzel's pBase page:



Compare with the Jupiter-11 Sonnar clone:

Congratulations. Attila has the Spiratone branded version and has shown some nice shots. It's a lens on my wish list.

Niiiiiice. Cool

Congrats Abbazz! Nice price

So, the widest part of the lens is basically solid glass? Must weigh a ton.

What a great piece of glass - congratulations, Abbazz! I'm a bit jealous Wink

830g. That's a massive lens, could prove useful in dark places Wink

There's a photograph of the middle triple compound group on Pete Ganzel's page: http://www.pbase.com/pganzel/image/71179359

Congrats, what a find! This F/1.8 135mm Sonnar copy was even cheaper than an East German or Russian F/3.5-4 Sonnar clone Laughing

Cheers!

Kelly,

While I try to locate some pictures taken with this lens, here's a link to the wonderful "prom night" pictures posted by Attila in the Gallery (he owns the Spiratone version of this lens):

Impressive !

Very nice Abbaz, i am still hunting for your other recommendation vogitalander 125/1.8...
The bokeh seems so beautiful, colors a tad less on saturation.
A very good lense it seems..
#3 is rocking shot.... !!

Bokeh is like an illustration, thanks for sharing.

Dakoo, I think you mean 125/2.5? And speaking of the Lanthar Abazz, do you find the faster Sigmatel showing you an interesting character vs the Voigt? The pics certainly look different bokeh wise, I guess I'd wonder how much you bother to carry the 1.8 around having a Lanthar?

I love the Lanthar, but I'm always game for fresh new bokeh Smile

Thanks guys for the compliments.

This is an interesting comparison. Both lens have approximately the same bulk and weight. The Apo Lantar 125/2.5 is indubitably the better lens. Wide open, the Sigmatel 135/1.8 has many aberrations and is notably soft and low contrast. It also has a greenish cast. But I like the bokeh, which is a typical Sonnar bokeh, creamy and easy to the eye. So I keep the lens -- and going to F/1.8 with a 135mm can be useful at times.

When I need a top notch all-rounder, I take the Apo Lanthar. For low light events or creative bokeh sessions, I take the Sigmatel. When traveling light, then that's the Olympus 135/3.5 or the Tamron 135/2.5 that goes...

Cheers,

Abbazz

"The bokeh seems so beautiful, colors a tad less on saturation" -dakoo

I recently used one of these, and in raw mode I added saturation. The result was more realistic, not garish blocking. It "worked", so maybe here, too.

I hope to compare to CZ Planar T* 135/2 soon. I did compare 3 of the 135/1.8's which might have proved that painting the triplet black does help contrast, or maybe I just under-exposed due to different real ap hole sizes at same nominal setting i.e. @f1.8.

Don't compare a brand new Corvette with a cheap old used car , they are not in same language in any aspects.

Congrats, a nice lens!.
As usual, we await for your samples Smile
Thanks!
