For the times you don't have your tripod with you, the IS on this lens will prove very invaluable for helping you steady your shots, especially at the 105mm end

great shots were missed by being bumped, or subjects moving a little too much to get a crisp shot

Outside of this "sweet-spot" (i.e. below f/8 or above f/11) shots of distant objects are *noticeably* blurrier

I use it on my Canon 40D and my brand new 5D Mark II, and get excellent shots that are crisp and clean, with good saturation and pleasing color

Image stabilization is excellent which means you can take full-range telephotos hand held and still get crisp shots

I use Lightroom to enhance my shots before developing

It is an image stabilization lens, which allows you to shoot somewhat slower handheld shots than would otherwise be possible

5D MkII's low noise at ISO 3200 yielded excellent available-light shots, indoors and out at dawn and dust

I bought this lens as a trial and after shooting 100 frames and looking at the results on the screen, I was blown away by how much better my shots looked and how crisp my images were

The image quality is everything you'd expect from a Canon L-series lens, while being incredibly easy to use (even someone unfamiliar with DSLRs can take great shots with the AF on)

Then I started to test the lens and compared it to the other lens I have, I have an EF-S 17-85 (designed exclusively for cropped frame sensors, 7D and below) that comes closest to this L lens, and as far as picture quality, the shots I took with the EF-S lens actually looked better than this L lens

The 24mm on a 5D full censor makes for great wide shots

It gives me just enough wide angle to get good landscapes and indoor shots and the zoom is excellent for portraits and other distance shots

great shots were missed by being bumped, or subjects moving a little too much to get a crisp shot

but it does allow you to get some beautiful closeup shots

I realize that in most cases that won't be true, but it was in mine!I took some pretty good shots of the March shuttle launch with the lens, but I do wish I had a Canon EF 100-400

I could take usable shots at 105mm with a shutter speed of 1/8

The IS means I can get cleaner shots hand-held than with the 24-70

I can get great wide angle shots and can do a decent zoom.

Makes great shots from anything.

I took some fantastic shots with it all day long.

Some of the most exciting shots were

Its image quality is quite comparable (perhaps even slightly better), but the 70mm is a bit long on a crop body to allow me the flexibility to take some other creative shots

L is the only zoom lens I own, and the shots are clean!A test of my 50mm

It can get up close, but still has the reach to get nice shots from a bit of a distance

I have seen sharp shots with this lens at 1/10 second handheld.

I went back inside and looked at them through the camera and zoomed in with the in-camera zoom and was shocked to see that when the zoom was maxed out the shots were still clear and sharp.

Upgraded from the Canon EF-S 18-135mm and the difference was incredible

(Note: it has an EF-S, not EF mount, so it's not compatible with the
