Lens WIDE-OPEN, Any Lens, Any focal Length, Any Mount, Any Camera

Product of the Fifties
This is the Companion to the F1.4 and Faster thread.

There is nothing wrong with your Camera.
Do not attempt to adjust the picture.
We are now controlling the image.
We control the horizontal and the vertical.
We can deluge you with a thousand blur circles or expand one single image to crystal clarity and beyond.
We can shape your vision to anything our imagination can conceive.


Using a lens wide-open essentially pushes it to the Design Limit. It's like the Optical Engineers "Outer Limits" for lenses,

Leica 5cm F2 Summitar, wide-open.

"Swirlies"- the Leica lenses are "Double-Gauss" highly Symmetric designs. The Football shaped bokeh is caused by Astigmatism.

Nikkor 8.5cm F2, wide-Open, ISO 10,000, 1/25th Second. This lens was introduced in the late 1940s, and got the attention of David Douglas Duncan. He did not buy one of these, but did but the Nikkor 5cm F1.5 and 13.5cm F4.

A very late KMZ Jupiter-3 5cm F1.5, made in 1956.

This Jupiter-3 is very rare. Most KMZ J-3's have German Glass, German Components, and even lens elements made during WW-2. In 1954 the supply of Schott glass was running low, and the optical formula was recomputed using Russian glass. A Limited run of these lenses was made, this one has the highest serial number I've seen for a KMZ J-3. The rear fixture is different from the earlier lens using German parts. Overall- performance is not as good as the lenses made with German glass, and KMZ turned manufacture over to ZOMZ.
 
This is with one of the very first coated lenses, a 1936 5cm F1.5 Carl Zeiss Jena 5cm F1.5 Sonnar. This is about 2 years before Zeiss started marking their coated lenses with a red "T", which stood for Transparent.


(Despite what the EXIF says!)
