Bokeh with 35/2.5 Classic? I doubt it almost...

[Graham Line]

Nice picture. You're still confusing terms as most people use them.
Foreground/background softness is a function of depth of field, which is governed by focal length, aperture and distance to the subject.
Bokeh refers to the appearance of the out-of-focus areas.
Here's the standard text on it: http://www.luminous-landscape.com/columns/sm-04-04-04.shtml

I won an award for bokeh with my 35mm f2.5 Color Skopar with this picture http://flickr.com/photos/53359808@N00/219416444/

You are muddling up a lot of things here. The 35mm f/2.5 will produce the same out of focus area as any other 35mm f/2.5 lens. Your ND filter isn't working any magic.

Also, am I the only one who hates the word bokeh?

Subject was close in this one, so you get that very oof background.

OK, maybe I'm confusing DOF and bokeh here, but the ND filter offers me the possibility to keep the aperture open even in dayllight. So I guess it is also responsible for this.

Bokeh is just the dinner party version of DOF, an affectation, about as daft as describing an informal portrait as Moyogi

Now you've got it. The ND lets you use a wide-open aperture even with faster film. Just don't forget it's there. The DOF scale on your lens ought to get you a general idea of what's going to be relatively in focus.

Having owned both the f2.5 Skopar and the f1.7 Ulton, I can confirm that the Ultron has much better bokeh.
This is partly due to the wider aperture. However, when using the Ultron at full aperture, out of focus points of light are rendered as really pleasant globes. The Skopar produces donughts.

Okay maybe I should try another roll and put all attention on the distances and an open aperture. But actually I'm used to getting kinda close...


cjm,

yep, they're nice but the tags are a bit confusing, though. He could also have tagged the 35mm because of the film size. i've just written him a mail. We'll see.


But hm.. I also don't want to get THAT close all the time to get a decent bokeh. For instance... If I did this picture here with the 35/2.5 I'm pretty sure that the background wouldn't be as blurred as it is here. It's made with the Ultron 35/1.7.

Hey, thats my photo! and i don't even know its used for reference.
