Phuang, this pic is a very good reason to discuss the meaning of the term "3D" s it applies to photos.
To me, the woman herself looks quite flat (compressed) even though it's only a 60mm lens. Additionally, while the backround is clearly way behind her (one type of 3D, for sure, it almost looks like a cinema blue-screen effect. I get the sense that she is standing in front of a rear-projected image.
Weird, but very cool. Now, is that 3D or is that dual-2D? I dunno ......
When we say "3D" are we talking about the entire image, or depth in the face / body in the foreground? For the latter, I think Spyro's CZ85 shot is pretty spectacular.
Perhaps we need more than one term for these 3D effects. Or even MANY terms, like Eskimos & snow....Show more →
I completely agree with this.
Dual 2D and 3D sums it up. The first look I associate with Leica lenses, and the second with Zeiss. It may be due to any one of many factors. It seems to me that the Zeiss heightened edge contrast and neutral bokeh go hand in hand. You seldom see soft bokeh in combination with the trademark Zeiss 3D effect.
Of course, there are many compositional methods which help to accentuate the difference between the focal plane and the unfocussed areas, but that is quite a different subject of discussion to that quality in lenses that enables subjects to jump out from the screen/print as if they were really there.
On the long 3D thread here there was a photo of some bluebell woods where everything was sharply in focus, and yet it had a sense of 3D and space that was breathtaking, even in a web graphic. The lens 3D effect can appear regardless of whether there is focus differential in the image.
I have a Contax 35mm f1.4 and a Canon 200 f1.8 both of which produce superb 3D effect without even trying. The 3D effect that I pay good money for is nothing to do with focal length or how I compose the picture. It is a quality in some lenses, and I'm afraid that it is rarely found alongside soft bokeh. That explains why the pin-stripes were resolved on the previous page, against all odds, by the Zeiss voodoo lens. Look for very even (neutral) bokeh in highlights, and higher contrast on the focal plane than off it, and often you will find lens 3D effect. Here's an example:

This is why I use the Contax 35 f1.4 and not the Canon. The Canon is certainly sharper in the corners, but it has soft bokeh instead of neutral bokeh.
Here's my hackneyed example of the kind of 3D effect I look for in a lens:

Here's the 200 f1.8 pulling off the same trick:
