Just for the records, every lens creates bokeh. What people sometimes intend to say is that some lenses produce more beautiful bokeh than others. To some people "bokeh" means "good bokeh", or "pleasing bokeh".

I think we can all agree that pleasing bokeh is achieved when the background goes smoothly from sharp at the focus point, to completely and uniformly blurred away from the focus point. Good bokeh will isolate the subject from the background. A lens delivering good bokeh will show a pleasing out of focus blur even when the background is busy (think a branch isolated from the rest of the tree).

Now that we're done with definitions (hopefully we can say that, in general, most 50 lenses are quite good optically, and their fast apertures will deliver pleasing bokeh, when compared wth other types of lenses.

And just for the record, I think it's safe to say that some PEOPLE create more beautiful bokeh than others...

Here's another page with various shots of bokeh for comparison:

Nikon Lens Bokeh Comparison

All but the last one were shot at f5.6. I like the last one best, since it is the least distracting of the bunch, but for some people, it still might not be good enough.

Or check out this one:

What is bokeh and DOF tips and photo examples

The photographer created that buttery background by holding the fallen jade vine against the bunch of other flowers. He also stepped a decent distance away.

I love his site, too, especially his How-To section.

As much as I admire perfectly smooth bokeh, for me it can go too far, rendering the background into a bland mush. That's the toughest part -- giving some personality to the background without having it distract the object in focus.

So this isn't the F/64 Club Is it?

The first time I noticed bokeh as opposed to OOF areas was on Henri Cartier-Bresson's original print of the couple on the train at an exhibition about 35 years ago. It's the area of the mans trousers in the foreground, which sadly doesn't show up on small prints, for me it was what actually made the photograph and I can't say I've noticed it anywhere since. Friends at the time thought I'd gone mad.

Wish I knew what lens he used, obviously wide open.

link to a poor copy ot the photo, but you can see that the man's trouser legs are different

Move the rear objects further back to get a better idea. With Bokeh you really shouldn't be able to determine with the OOF objects are, though in many cases, it's obvious (lights, vegetation, etc). The definition seems to vary wildly though.
Yes, after reading some of the posts last night, I was thinking about good bokeh depending (at least in part) on the distant objects being further away.

Although this is not as blurred as some photos in this thread, does this qualify as bokeh? (DA70 @ F5.6)

The very background, I would say so. Have to look through all the twigs to see it though .

Yes, it certainly is an excellent site.

I think some people enjoy the bokeh more than the subjects themselves. It's like some people like to spread a little butter on their bagels, some enjoy it with a thick layer of soured cream.
