Optics Theory - This forum is aimed towards the TECHNICAL side of photographic OPTICS THEORY. There will be some overlap by camera/manufacturer, but this forum is for the heavy duty tech discussions. This is NOT the place to discuss a specific lens or lens line, do that in the appropriate forum. This is the forum to discuss optics or lenses in general, to learn about the tech behind the lenses and images. IF you have a question about a specific lens, post it in the forum about that type of camera, NOT HERE.

Bokeh examples

On this website: https://flashbackcamera.jp/photogall...ist_type=alpha Bokeh examples are available for practically all photographic lenses.


The list is too long to copy.

My favorite is the Cooke Amotal. Never heard from this lens, but it is incredible.

Interesting, thanks, though there are many “bokeh” lenses that aren’t there I’d imagine a complete accounting would be close to impossible. Good effort though.

That lens was made by Cooke for the Bell & Howell Foton camera.

That camera turned out to be a bit of an overpriced flop at 700 USD in 1948 so a well known US camera store bought the surplus lenses and had them mounted in a roughly made aluminium helical body in LTM in Italy (and even a few were made to fit the Contax RF camera) and sold them with Leica cameras .. as there was some loophole where this camera store could sell a new Leica body with a non Leica lens for much less money than Leitz dictated to their US dealers for the usual Leica with a Leitz lens in the early 1950s.

The lenses were made by Taylor, Taylor and Hobson in 1948. They sell like hot sandwiches nowadays; the lens heads are placed on old Leica screw mount flanges to make them fit on digital cameras.

I do all my own black and white developing at home.

Another great site with tons, and tons, and tons of lenses from the pedestrian to the most exotic:


https://spiral-m42.blogspot.com/


Each blog post goes into a little history and sometimes the design of the lens.

Maybe it is not a bokeh-king like the Dallmeyer Super Six 2'' f/1.9 but the rangefinder Nikkor 50mm f/1.4 certainly delivers a nice dreamy image from time to time.

Nikon S2, Nikkor 50mm f/1.4, 400-2TMY.

Erik.
