Where 3D-like effect comes from – a hypothesis
9 months ago

Just a crazy hypothesis of mine…

I think that physical size (diameter) of the lens’ front element affects how much of the subject is visible to the sensor. Larger lenses on FF camera can see more circumference of the subject than small lenses typically used with small-sensors cameras.

The picture below is exaggerated to illustrate the issue. Of course, other factors, like wider dynamic range, use of RAW or better JPG compression engines, less noise, higher resolution, weak or absent AA filter, lens IQ, and others affect the photo.

The effect should be more noticeable on closer subjects and larger lenses. It is somewhat similar to binoculars – the pair with bigger distance between object lenses gives you “super 3D” picture.
