Interesting experiment. I like the empiricist. Especially with regard to the
mythical 3D-pop. Glad I'm not the only one with GAS as I just picked up a Voigt
50mm/2.
I assume these are shot using an A7x?
At 70mm, the Zeiss looks sharper or crisper which makes it stand out more from
the background.
At 35mm, the Tamron background seems more blurred? compared to the other 3.
Could be just the way it renders bokeh. But again it appears the Zeiss is
sharper. Looking at the lower left of the subject, the rock quality just seems
to have more tonal variation. Is that just sharpness? or more contrast?
Perhaps the Zeiss is sharper wide open compared to most lenses, giving it even
more of the pop compared to other lenses wide open.
As far as I can tell, it seems the 3d-pop-ness is combination of sharpness +
contrast + bokeh, at least in this experiment. Correct me if I'm wrong. Curious
what others see?
I wonder if you applied some topaz magic sharpening, if that would change how
these are perceived?
