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.

Are dslr lenses allowed, or is that blasphemy?

Some Large Format Bokeh

This thread has taken on monstrous proportions! Herewith a Bokeh contribution from a monstrous camera:


(Ilford HP5, 4x5in sheet film, exposed in a Linhof Technika V with a Schneider-Kreuznach 150mm APO-Symmar f/5.6)

Shot wide open - in my copy of this lens - the 6 diaphragm blades never fully move out of the way. I am not sure if it's supposed to be like this (never handled another one) but it has a visible effect in the rendition of out-of-focus highlights. I still like the shallow DOF capabilities (often surprising to small-format shooters, since it's only f/5.6).

This image was printed in the darkroom on 8x10in Ilford MG IV paper, and the print scanned.

The Leica Summicron 35mm f/2.0 might be one of the best 35mm lenses ever created, but it surely has among the most unpleasant out-of-focus rendition of all lenses. Absolutely harsh and clinical, with bright-edged halos, as demonstrated by the shot above.

I think the 'cron 35mm is much better suited to distant (e.g. landscape) imagery. Thank you for posting the informative sample! Every now and then the though of getting one crosses my mind, but if one cares more about the general aesthetic of an image than just resolution, the appeal simply melts away... (unlike the summicron's backgrounds!)

P.S. This post is not to pick on you or your image, just general observations about the lens.

Ok, one more. I can't resist. I just really dig the bokeh this lens gives.

Yes, I recently wrote that I didn't care for my 35mm F 3.5 Serenar, and the reason was Bokeh. But I have learned to live with it. I also like my 50mm Elmar F 3.5 which is like the above:



My favorite is the Apotar on my Isolette, wide open F 4.5:
