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.

Don't remember the lens, but I think it was summicron 90/2 on the Epson R-D1.

after 26 pages: Can anyone give me an iron-clad definitition of exactly what "bokeh" means? I defy you to find it in the dictionary.

Update - I did find it with some help from Google. It seems to mean the quality of out-of-focus areas produced by a lens under shallow depth-of-focus conditions.

Now explain that to Ansel Adams, Edward Weston, and any number of others. Except that they probably didn't have the problem, since they took most of their pictures at f/32.

I've edited it with iPhoto, but the "bubbles" in the bokeh was there from the very beginning.



Camera: Epson R-D1s
Lens: Dallmeyer Super-Six Projection 1 3/4" f1.9 @ f1.9
Color tone changed with iPhoto

I haven't posted to this thread in a while - glad to see its still running! Here's a couple of shots for comparison. Both are taken with a wartime CZJ Sonnar 50mm f1.5 on the R-D1.

@f1.5 - soft and abstract, with foreground veiling flare:


All the way to f4.0 - still has a very impressionist look:

The first shot was taken with a Leica Digilux 3 using a Vario Elmar 35-70f4 lens on macro. The second and third were taken with the Summilux 25 1.4D.

Enoch, Ali, and Hans, thank you for your kind comments.

Hans, I believe you found my Flickr, yeah?

Lately I've been enamored with a Rolleiflex E2 2.8 Planar that I purchased from another RFF'r. These shots don't make dramatic use of BOKEH, but I think the Rollei renders the out of focus areas beautifully (I'm excited to try it with Macro adapters)...

Not a RF but I wanted to show my Pentax SMC-M 50mm F/1.4 using a custom hood to produce swirly bokeh . Some people love swirly bokeh ( including me ) . They say it's much better to use a hood on the rear element instead of the front element but that's kind of diffucult sometimes . This lens is a favourite and produces very good bokeh ( with or without the custom hood ) as some people have already shown in this thread.

I shot a fuji velvia box against a crumbled tin foil using a Pentax K100D ( APS-C sensor ) .

I'll come back with some better pictures using my custom hood.

Hi Mer, how do you mount a hood on the rear of the lense? Sorry for my ignorance.

@rogue@hans- ooh . I don't care- I like the colours and the dreaminess of it.... I can differentiate between what's in focus and what isn't, I thought the overall effect was enough to justify keeping it.

Hi,
I came across a guy in flickr modified a Schneidier 50mm lens and used with Leica M. You may want to search. I suppose it creates more swirls than others. And he has some other fast lenses modified too. Another one is Angenieux.

His nick is doo3, all of you must visit his gergous site.
