http://www.asgvis.comYes, and if you had read the entire thread you might have noticed that I brought that up.
Most of the other plugin renders do as well, as do the dinosaur modelers like Max and Maya or oddities like Piranesi and Blender.
But isn't it nice that you don't always need them? SketchUp has the capability without plugins or additional software.

hi,
i found this tutorial on you tube.
i was wondering which version of photoshop is required: mine is 7.0.1 but it doesn't have "lens blur", it has four or five kinds of blur but not this one. -
oooh, i'm going to have fun tinkering with this tonight...

My cursory search of the internet suggests it was released as a new feature in CS.

Remus is correct...it appeared with the PS CS versions.
However, you can achieve the same effects by using the "depth mask" as an alpha channel and (depending on what you want to do...make the near blurred or the far blurred) simply use Gausian blur to throw the area "out of focus." In fact, this will also work with other image editors such as GIMP (which incidentally has a Gausian filter capable of finer tuning than Photoshop's).
The Photoshop CS lens blur filter complicates matters needlessly. I almost never use it.
Incidentally, once you have a depth mask as an alpha channel, you can control its relative strength using Levels on the channel. Want things to get blurry real fast, as if you used a telescopic lens? Increase the contrast in the depth mask channel.
I also use depth mask channels to simulate the watercolorist's traditional "atmospheric perspective"--in other words, things that are far away are more gray (desaturated) compared to foreground objects.
If I have a little time later today I'll post some examples.
