Is my lens sharp?

Just got my 70-200 2.8 IS today!! First impression is that it is smaller and lighter than what I thought. At first it looked greenish grey but I looked at it again later in the day and it was beige (maybe the sun light changes the color like our license plates? :confused. Anyhow, I took a few shots to see how the lens performs. What do you think- is it sharp?

note: shots were taken with UV filter on, shots taken at 2.8.

1st pix are original (just resized) and 2nd pix are 100% crop.

Questions first-
1) did you have a chance to check the focus of the lens?
2) What body do you have?
The reason that I ask the body is to find out if you have the live view function. If you do, you should use live view and manual focus to compare with this pix. I assume you use AF for these shots.

I'm not sure what you meant by check the focus?? I just used AF like you said and took the shots. Since it's 1.4m to infinity I had to stand about 4ft away to get it to auto focus.

I currently have an XSi. The fox tails and the dog look pretty good to me at 100% crop. The bird and brick wall, however, look blurry.

Thank you! He's supposedly a pomeranian but it looks like an american eskimo mix to me. My brother's friend has one and it looks just like ours and it's supposed to be a pom too so I'm not sure...

The good news is your lens is probably well within spec.

The bad news... you have to send your dog in for calibration.

setting,ISO, shutter speed, Aperture, light condition, White balance. forgive me for i dnt know how to check the photo data.

Generally, you will want to mount your camera on a tripod, MF, use LV @ 10X to confirm focus, use MLU and remote/cable shutter release/timer to take the shot. Process image if in RAW to JPEG at highest quality and post original picture and 100% crop of focal point. Leave EXIF intact.

PS - The images you posted have EXIF so keep posting that way.

2.8 for all of the pix (taken around 6 PM so still plenty of light out), ISO 100, auto white balance, JPEG instead of raw but I don't think that will make such a big difference (ran out of memory).

That would be great news!

Lol- I can't tell sarcasm with no emoticon but if you're talking about the tear stains then he's had them ever since we first brought him home.
