50mm f0.95!
I know, that large an aperture is a bit too much to ask, but why not a f1 or even just a f1.2 with AF? Right now, only canon has something that fast! Bringing a lens like this to the table would probably make a lot of serious enthusiasts reconsider what Pentax has to offer!
But anyways... Someday I will be rich and I will buy a leica... maybe
range finder lenses are slightly different in construction, one
Originally posted by séamuis the difference between a 1.4 and a 1.0 isn't all that much so why does one need it? and even with AF you'd be lucky to get any shots in actual proper focus at that aperture. what practical application can you use such a lens? and how would it do the job any better than the 1.4's currently offered by pentax?
using this:
Online Depth of Field Calculator
at 2 meters, 1.4 vs 1.0 on a 50mm will yield almost 4 cm of extra DOF
at 3 meters, 9cmm of extra dof
shooting someone at 10 meters away, will allow you to have a mere 2.4 meter depth of field (total) @ 1.0 vs 3.4 meters, thats a whole meter of background that will be eliminated.
for some creative work, this is quite valuable.
like wise, lets take the 21mm f1.4 from leica,
shooting a person at 2 meters away, will have a total DOF of 79cm, just enough for the person to be in good focus, with everything else OOF... just TWO meters away!! that means you can have a person stand a mere meter away from a wall, and it will already be blurry!!
the modern pentax equivalent, at a silly f3.2 changes the depth of field to a full 2 meteres! meaning that pretty much everything in close vecinity will be in focus, and then its just like a P&S shot.
