Lens design has a lot to do with how bokeh is rendered. I've been
shooting film almost exclusively this year, a lot with a Pentax 6x7 and
105mm f2.4. That lens seems to have been designed to produce the most
beautiful creamy bokeh possible. I also use a Ricoh Diacord TLR, a 6x6
TLR with a f3.5 Tessar design lens. The results are incredibly sharp
but you really can't get a smooth bokeh. Forms clump together and
highlights in particular render as circles with almost crisp
circumferences. Each lens has its own purpose. The Pentax lens lets you
easily isolate a subject against a soft background, giving the nice 3d
look. But the Diacord is almost magical in creating the appearance of
infinite depth of field, even when only stopped down to f8 or even f5.6.
I think one issue is that there is no real agreement about what makes
for a "good" bokeh. The lens in the Diacord seems to have pretty typical
Tessar type characteristics, including the "clumpy" bokeh. But a lot of
folks seem to like that - especially in the rendering of specular
highlights. Others look for a creamy bokeh with everything running
together.

Yes I agree thats the main effect. However this guy even includes lead in
glass as a pop factor. The rendering of bokeh also adds to the effect.
Zooms have a busy bokeh.

I can hardly see the difference in his before after shot with the slider

What is seen as 3D “pop” is just limited depth of field. And because
primes generally have a larger app wide open than zooms, they give you more
control over DOF.

That certainly does "pop"!

I read a lot about primes vs zooms and old designs of primes. That
should result in something like 3D pop. Never noticed it until today:

I find myself lugging the DA*300 around on a daily basis. Maybe because
it
pops.
Do I need new glasses?
