Steinheil f1.5 25mm Quinon (c-mount) on GH1

[kds315]

Steinheil was always known for their good lenses and the Quinon is known for its sharpness, so when I discovered that c-mount beauty, I jumped....

Now a test: Vignetting, distortion, sharpness test. The former Witchtower here at the Weinheim castle, ca 15m away. Original shots, just resized.

f1.5:

f2.8:

f5.6:

f11:

f22:

Note some barrel distortion and disappearing vignetting, much increasing sharpness/contrast from f2.8 onwards. Sweet spot around f4-f5.6 IMHO.

Wide open I have to try some portrait shots...(note the "glow")

glow, or serious softness...

Rare lens:thumbs:

I am looking for one of these. I missed buying one when Rabe sold one a while ago.

looks like there is noticeable CA..

 

[kds315]

Yes, there is some CA and there is also some distortion closeup, but nevertheless a fine lens, which renders nicely. Hard to express in tech. terms though. When I see another one, I'll drop you a note!

 

[Vivek]

Thanks a bunch, Klaus! Much appreciated.

BTW, What is the filter size?

 

[kds315]

Most welcome. Asd you may have seem in my pic above, it looks like there is no filter thread mount, but clever as Steinheil engineers always have been, that is just a decorative ring which can be unscrewed easily (it has been made for that purpose) and under that is a 33mm filter thread mount.

 

[Vivek]

Thanks for the info.

The wide open shot- was it made with the decorative ring intact?

If so, without it, wouldn't the corner darkening/vignetting be better?

 

[Vivek]

I offered a decent price of $200 for the beat up one on eBay but it was declined.

The one with the asking price of USD 750?

 

[Vivek]

Yes, the one that looks like in need of a total rebuild.

 

[Jonas]

Sometimes I don't know what's up with the prices for these motion picture lenses. I feel sorry for those shooting, or wanting to shoot, 16mm film; maybe it is as simple as they are rare... anyway, people tend to pay a lot for them.

For us the situation is a bit different. We have at least more choices making us get by while finding the lens.

 

[Vivek]

There is no obvious advantage to buy this Steinheil lens unless one has a hacked m4/3rds body to go with it.

16mm users will not miss this lens at all.

That's what making it a mystery. My guess is that most µ4/3 easily would find other options. I don't see anything in this Steinheil lens justifying a price tag of several houndred of dollars. Maybe it is something for a collector?

Or, I am mssing something.
