Not the educated ones, who would know that the EF-S 17-55mm f/2.8 IS on a crop body is out-spec'd by the EF 24-105mm f/4L IS used on FF, since the FF-equivalent of 17-55mm f/2.8 is 27-88mm f/4.5 (becuase the crop factor affects aperture in terms of DoF for equivalent framing), and the 1-stop effect on shutter speed is more than compensated for bu the 1.33-stop improvement in ISO noise with the additional light gathering ability of a FF sensor). So, the 24-105 on FF is wider, longer, and faster than the 17-55mm on crop, still has IS, and is weather-sealed with L-quality build to match.
Having said that, the EF-S 17-55mm f/2.8 lens is, IMO, the best general purpose zoom for a crop body (although the EF-S 15-85mm f/3.5-5.6 IS is a good alternative for outdoor use where losing 1-2 stops of light is tolerable).
Here are a few of my shots with the 17-55mm:
EOS 7D, EF-S 17-55mm f/2.8 IS USM @ 17mm, 1/3 s, f/22, ISO 100
EOS 7D, EF-S 17-55mm f/2.8 IS USM @ 55mm, 1/2 s, f/13, ISO 100
Rebel T1i, EF-S 17-55mm f/2.8 IS USM, zooming during exposure, 1/20 s, f/22, ISO 100
Thanks for looking!

I think what they mean by making FF owners jealous is that the closer equivilent lens would be the 24-70 2.8 which lacks IS.. Because if they added the IS to that lens, that would be the choice for a all around lens for FF bodies.

It shows 37mm. I took the shot over a year ago, and as I recall I started at 55mm; I'm not sure if I ended at 37mm, or if I zoomed out furtner and it just used a value near the middle (the midpoint of the zoom range is 36mm). I sense an experiment coming on...

Yes, I am extremely curious when that gets recorded. Perhaps at the very end of the shot.neuroanatomist said:

Celebrating 20 years of model photography!
You guys are making me jealous! I've been trying to make my EF-S 17-55 work properly for months on my 7D. It front focused very badly at the wide end of the zoom range, but was fine between 28 and 55. Sent it to Canon for repair and they fixed that but now it back focuses at the telephoto end of the range! Sending it back in today, hope they don't charge me again for repair.

... exif is missing - I take it these were shot at f2.8 and are 100% crop pictures? At what zoom range? Personally, I doubt the helpfulness of posting pictures for lens reviews because you can good and bad shots out of most lenses - but at least the basic information should be there.

Exif was there before uploading. I don't know why it was erased.
55mm, ISO 100, f/5.6 50% cropped and then resized from ~1800x1200 to 900x600.
I'm not doing a review, just posting some shots I took with that particular lens
