A while back I posted a couple of threads on 3-D, as some of you may recall. The reception to these in the forum was pretty hostile on the whole.
Some acknowedged seeing 3-D in photos, others didn't, some didn't like the word 3-D (preferring POP or something else), some associated this with Zeiss and snobbiness, some didn't like discussing this seperately from the image itself, and some suggested 3-D could only be achieved by stereoscopic lenses and 3-D glasses! Quite an educational couple of threads for me...
Anyways guess what! Canon have used the word 3-D for the new 24-70L II!! Had a good chuckle when I read this. Honestly thought I was reading about a Leica or Zeiss lens.
"The lens delivers higher image quality and enables users to capture images with greater presence and three-dimensionality"
IMHO at times characteristics like sharpness are overly enphasised. A lens can be sharp but can lack character - bokeh, colours, rendering, tonality, microcontrast etc. To me these are more readily apparent in a typical photo, sharpness is not.
