For your viewing pleasure I have cropped a section to show actual pixels so you can see the focus better.
So this is showing handheld at 600mm at 1/2 stop from wide open on a Tokina 400 + Sigma 1.4x converter. Then handheld at 1/350 sec. I'd say that the SR worked pretty well. I think the focus is about as good as that combination of lenses is going to do. http://www.daytonphoto.com/PAW/ggpark_065b.htm -- Best regards, Bruce Monday, December 4, 2006, 4:07:51 PM, you wrote: SB> Doesn't look very sharp to me - certainly not up to your usual standards, SB> Bruce.
