Hi Ziggy,
I use the Jupiter 12 in both the Kiev mount and LTM. Both are quite sharp and contrasty fine lenses. They DO NOT have any 3D qualities I've noticed. HOWEVER my Leitz 35mm Summicron DOES have that quality.
All the best,
Sam H.
Buy longest lens possible you can use with aperture of f2.8 or wider. best way to get compressed, out of focus backgrounds, devoid of recognizable objects. makes stuff pop with sharp accurate focusing!
I've noticed that photographers who are accustomed to shooting the relatively slow
zoom lenses found on today's cameras are impressed by the shallow DOF produced
by faster primes which we who shoot "old fashioned cameras" often take for
granted. They often call this a "3D look" because it provides a visual sense of
depth to an image. Some also use terms such as "pop" to describe it.
