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.

The really interesting thing about this thread is--as someone said--the photos ALL outweigh the bokeh. So--it looks to me like if the subject is interesting--well--where's the bokeh thing? A really good photo just seems to be a really good photo, no matter what....and there are some great ones here.
Thanks to all!
Paul

Hi Letien,
Yup, Rolleiflex 2.8C. If I had to have only once camera, it would be my Rollei with Xenotar. I just love the lens. I'm with you, just enough so that the other areas are not too distracting. Too much swirly stuff, odd looking (to me) bright-ringed donuts, double lines, I find noticeable in a photo. It's nice when that stuff isn't noticeable.

Edit: 2.8E

Fisheye lenses are not conducive to selective focus, but the Canon EF 15/2.8 has an appealing point-spread function. The five-bladed aperture, on the other hand...

And a sample that shows that even some of the "best bokeh" lens can find themselves streched beyond their limit (raising fist like Col. Klink: "tree foliage!")

Rico, That's a great cat photo. I agree, the bokeh in this case could be said to be distracting. OTOH, it seems more like an additional element to me, and I think it works. The subject's very prominent (and shiny) eyes, and the OOF highlights complement each other.

I agree. This "distracting" bokeh actually adds some sparkle. Maybe a slight crop would balance things, but otherwise, it seems to work!

Thanks, Hans. I thought the setup would produce an interesting result at the time.

here's a good example of bad bokeh.

Taken with Canon dRebel with 70-300mm DO (Difractive Optics). This lens tends to render a buzzy background as a blurry buzzy background. Very distracting.

Please mention if you are using filters. Not sure if it has much effect, but I'm seeing stuff here that I don't think should be seen with "proper" lens usage...

A few photos from recent scannings that display some nice bokeh, all from a Canonet G-III QL17, most likely @ f/1.7 or very close.

Magdalen College playing fields, Oxford, [email protected]


Christ Church Meadow, Oxford, Jessops Pan 100 (which I believe is Ilford made).

This is rather odd bokeh. A boring shot (a bus shelter - spare me!) but it was only taken to test the sharpness of a 40 year old 300 mm Takumar. Sharpness is OK and no chromatic aberation but rather odd, slightly harsh, bokeh.
