Nice shots there! It looks like a really sharp lens as well. From the look of those Blue Ridge parkway shots, I'd say you've got a pretty good handle on cracking that code.
Ed, on that incredible picture of the recital, what kind of special lighting are you using? Did you use a teleconverter as well to get that? You've shown that picture before and it's one of my very favoriites. Mind sharing the exif?
I'll be interested to see what the 150 will do at our indoor agility trials. Need something fast. I heard the focus is kind of slow, but if we pre-focus on the equipment, it might help.
Thanks for your help--I'm off to work now! Someone's gotta pay for this stuff! LOL
Here's the EXIF:
D50 @ ISO 400
1/100 sec handheld
f/2.8 (wide open)
Center Weighted Average Metering Mode
Auto WB
Aperture Preferred Auto exposure
Lighting was just their normal stage lighting. I shot RAW and converted in PSE5 using ACR, correcting WB and exposure along the way.
For comparison, here is the uncropped image:
And, again, the cropped image:
This is *exactly* the kind of situation I wanted the 150 for. I really would have liked the 70-200VR but, for a third the cost, I'm quite happy with the Sigma, and also like the fact that it is truly a dual purpose lens.
As far as "action" shooting, I would not recommend it. I tried using it at my daughter's soccer tryouts a few days ago and, while I did get some good, sharp, in-focus shots, the majority were soft due, I think, to the (relatively) slow focus tracking on the D80. If, however, you were able to pre-focus in manual, it might do just fine. It is probably the sharpest lens in my bag (including the 50/1.8) according to the
MTF chart, and my personal experience. The optimum aperture is f/5.6, but the dropoff at f/2.8 is minimal.
