Nice images. Second one made me chuckle. I used to shoot images of my son's bionicle figures, then photoshop him into the image as if he were interacting with them.

And I had to chuckle at your signature. I guess addiction to sports cars does put photography in perspective!

Could someone tell me what to look for on this lens to tell if its US or import.
I see good prices but dont know how to spot a import, however not all the pics of them is clear enough to tell.

EDIT: Well B&H says theres no physical difference in the lens itself. Just rebates and warrantys.

Here's a couple of pics I took recently with my copy of this lens

I am still learning with photoshop and one day I'll be there.

One of these just arrived this afternoon along with a couple of other lenses and I'm more than impressed....It's MUCH sharper than my "old" Sigma 28-300 (I put old in parantheses because I've have it less than a month...haha!) This is a cropped image with some very light processing of the moon taken a few minutes ago. It was shot at ISO 200, 300mm, f/5.6, for 1/1000 sec. Not the best moon shot, but the best I've been able to get so far (couple of telescopes included) and this was done on a monopod:

slightly better done on a tripod...ISO 200, 300mm, f/8, 1/1000 sec. some cropping and minor adjustments done in lightroom. The clarity is nowhere near what I've seen in some other photos of the moon in this thread so some tips would be helpful

Just one more quick picture taken during the day this time. I am impressed with this lens. I have only had the DSLR for about a month, but the Sigma 28-300 I gave to a friend of mine pales in comparison to this lens (and this is far from the best image, I know):

300mm, f/6.3, 1/80 sec, ISO 100

it's been a while since anyone's contributed to this one...so here's a couple of shots

I just bought this lens for waterfowl photography. Does anyone have any tips for settings on an Xsi for in flight pictures? Thanks for any help you can give me

stop it down if it isn't sharp, either ai servo and center AF point or all af points.

I've read in previous posts here that f/9 is often the sweet spot, and at least on my copy of this lens, that seems to be so.

f/8 is the sweet spot (not sure how you even get to f/9).

I've been real pleased with my copy. Check out my flickr link if you want to see some pics. Unfortunately, after Christmas I'm going to send in into Canon for repair. Its suddenly become very soft at 300mm with some strange haloing especially with with anything white. I think something is out of alignment.

Ok changed my mind. Found my photobucket account and will post a couple of shots.

One near (100 mm)
