Originally posted by troglodyte If I had the bucks and liked range finders, leica has a 21mm f1.4. I can't imagine how wonderful that lens must be.
Also looks like there's a Zeiss compact 21mm f2, w/e that is. Can't afford either!
trog,
let me give you an alternative view from my last 18 months of shooting live plays for promo shots. we're not allowed to use flashes for rehearsals so initially i went out and bought some zoom lenses with F2.8. But for some dark scenes, i still had problems with bluriness caused by either human motion, DOF with more than one actor on stage, or tungsten effects. Then i learned from another photographer to be fearless about using higher ISO, up to 3200 or 4000 with my K20. If i have noise problems, i just clean them up with LR3 or Topaz5. Actually the new generation of sensors such as with the Kx, probably the K5 and/or the Kr will no doubt make the higher iso less noisy.
With higher iso shooting, i can now use my F2.8 lenses at F4, F4.5 or smaller allowing me less discards due to slight AF problems because of larger DOF. Also with the higher iso, i am more likely to freeze human motion due to the ability to use 1/125 or higher shutters. I recently snapped 450 images with probably no more than about 10 blurred images due to AF problem. My acceptance rate has gone up with the use of high iso.
I used my DA 21 f3.2 at F3.5 and even up to F9 recently for a wide angle picture of an evening play outdoors. Came out great!!! So what i'm trying to tell you is, you may want to spend your money on a camera with a more capable low light sensitive sensor than spend money on ultra fast lenses. I found that the DA 21 f3.2 is plenty fast for me for the kind of DOF i need. And i often dark scenes. IMO, low light camera first, fast lenses second. unless you are doing an entirely different kind of shooting. just food for thought :-)
best wishes with your selection,
