Haven't used the 50-135 yet..A bit too long. For lighting in studio, it depends on what I want to accomplish. It can be flash exclusively i.e. power pack with several head. I often mix tungsten with flash, HMI with flash and Kino Lites with flash. Have done stuff with pilot lights only etc etc etc...

Thanks for publishing your sharpening algorythm - all these years in photoshop (since about 2.3 for me - I remember when 4.0 was a big deal!) and I never though of doing a fine sweep and then a wide sweep in USM. Brilliant.
I'm still working on getting things sharp and nicely lit in my little bit of studio work: want to master the basics first:
*ist D: FA* 85: 2x500 watt second flashes with softboxes and one 250 W/S bare for rim light.
Now, about the K20... you were saying....
Cheers,
Cameron
