I found this lens for Aus$5-00 at recent camera mart. It has the look of absolute 1950ish quality: everything is as smooth as silk. The lens appears to be exceptionally simple in design, yet rather elegant. It is purely manual everything, but smooth as butter. at least 9 or 10 diaphragm blades and optics like crystal.
I fitted it to my Ashi Pentax SP-F and, using stop-down metering (which invoved manual setting of the aperture) took a couple of shots (yet to come back from the processors).
The lens was still in its original cardboard cylinder: no fungus, and clear as crystal when focusing: it should give great images.
As I said, no frills whatever; probably not even coated.
Anyone with experience of this or similar by the same maker.
Any info on the maker?
It is so compact, I almost suspect it was intended for a movie camera, or projector?
It certainly stands out from the crowd!

Ah well, found something here: http://photo.net/classic-cameras-forum/00MqmD
Apparently it is considered to be a lower form of lens life and probably a triplet.
Even so, it is a very well made item and I can mess about with it and see what it can do.
Worth the Aus$5-00 |

Lots of people do frown upon triplets, especially when more complex (and higher-priced) lenses are available. However, things such as the Hugo Meyer Trioplan 100/2.8 got them lost their minds these days, and I feel sure you will find the ISCO can open up many creative possibilities.
ISCO was Schneider's "second label", short for Jos. Schneider CO. They made some lenses similar to those by Schneider but have their unique fields, such as movie projection lenses, for which they won two Oscars for technical innovations. Nothing to feel embarrassed about! |

In fact there is not a lot of information on this lens. And there is not a lot I can add.
But I own a nice copy of it and sometimes like playing with it. I'm afraid there are many weaknesses, first, the lens is slow. It allows only high ISO or good weather outside shooting, exposure should not be too long because of the focal length. 1/125 sec for me is ok or a tripod is necessary.
Wide open there is some CA, but not too much.
Flare really is an issue on this lens. I always wanted to add a hood. There is no effective coating on the glass, maybe not even single coating.
What you get with this lens is a rare focal length and a really rare lens. It is pretty sharp in the centre. Bokeh for me is nice, f4 just right for a portrait-dof. And it is a pretty lens with zebra design, light weight and small size.
My samples are of no use for evaluating the lens. But I liked the pictures taken of and with the lens

Two more test shots from today. ISO 100, EOS 10D. Distance to the flowers about 3 m.
First shot open, second stopped down to f11. Missed focus a bit but good enough to see, that it is sharp, has triplet-bokeh, a bit swirly, some CA and even flares in the shadow.
Captured raw, PP with ufraw, standard settings, camera color profile, camera WB, sent to gimp and saved as jpg. Nothing more, nothing less.

And another test shot as comparison to the ones before.
Pentax Optio S30. I tried to simulate the settings of the Canon.
So even a not so good lens is waaaaay better than an old not so bad pocket cam

ISCO G is the secondary , cheaper line of Schneider.
With the exception of the late models made largely of plastic which were terrible- built to very poor tolerances ... the earlier ones were by and large well built and still beautiful to behold today.
Optically however, none of them are particularly spectacular from those I've had ... and those I've read about.
If you want a good performer, get a takumar instead. |

Interesting........I've got one of these and I've probably used it once. Perhaps it's time to get it out of the box?
