Absolutely no post processing (not even sharpening BTW) on this pic. 135L on the raw.

That's because the persons in the front are much closer to the camera than the rest of the scene, even the corn on the right is much further away. Normally you see a gradient of objects in focus to objects out of focus, but now it's an OOF object (persons in front) "on top of" an in focus object (corn).

Yes, I realized the compression effect of using the telephoto lens wide open was doing this but did not believe it could be to the extent that is evident in the image.
Pretty impressive. The effect somewhat mimics post production techniques such as can be seen here:

Glad someone else is seeing it too!

It was just a quick test shot from the other day. Walked by a local photo shop that had a used one for sale at a good price. Could not resist and the 3D is a bonus...'

Congrats Andreas. I've always really liked my EF 50/2.5 CM. Although, it might be on shaky ground now that I have a possible replacement on the way ;-) All a part of my down-sizing, bang-for-buck plan.

For me, 3D isn't only about shallow DOF but about finding something in the picture that helps relate to distance. Here, at f/2 (135L, not Alt sorry), the front and back OOF seems to help that 3D feeling. So, more than magic driven from German engineers, composition might have something to do w/ it.

Excellent 3D sample!

The 5D + 70-200 f/4 IS combo has the goods to produce some 3D-like images from time to time. When viewed in DPP they look way more 3D than here due to some DPP voodoo sharpening, I guess. Anyways, two samples.

Actually I think the f3.5 one has better 3D because the watering can spout stands out more against the more blurred background than in the f8 shot. However for the best effect you should copy the f8 watering can spout onto the f3.5 watering can spout with photoshop. This will give an even sharper spout standing out against a more blurred background and thus it will look more 3D.

I lose track of where I have posted what,
but I don't think I've posted this one in this thread yet.

Do the 3D spotters notice 3D in this one? I do, but it puzzles me why.
A close-up, and mostly out of focus regions too.
Yes, this is from Zeiss glass. Any guesses which?

Here is one more from the same lens.
Your guesses are close, but not quite there. Think "inexpensive lens."
