I bought this lens for a safari holiday based on these reviews. They are right - it is a fantastic lens. It is relatively light and well balanced on my 7D and I can walk around all day with the camera in my hand. It is tack sharp at all focal lengths, excellent contrast and colour.

Superbly sharp; relatively light; useful range; superb IS

Ugh None Here

I need to purchase some additional lens filters and eventually I plan to upgrade to a full frame camera which is another reason in purchasing the "L" Series Lenses from Canon.

I am new to DSLR photography and about 1 year ago purchased the Canon T1i Kit; I then purchased the Canon EF-S 55-250mm f/4-5.6 IS Telephoto Zoom Lens for outdoor shots; The pictures were fine and blew away any of the point-and-shoot pictures I have taken over the past 15 years.

None so far; I do have to purchase another camera bag for all three lenses

Its compact size and Light weight can be deceiving when put next to its bigger brother, But at its f4 aperture the performance of this lens is truly amazing the IS system works well Testing it i went as low as 1/13 shutter speed at 200mm with IS on and it kept on taking usable images ..

Easy to use; Compact; Build quality

I mostly shoot landscape and nature and this is by far one of the best lenses I've owned. Even wide open it's amazingly sharp and focuses very fast. It will hunt a bit for focus in less than optimal light, but compared to the weight and cost of its 2.8 big brother this was by far the better option...

Heavy

I had read about this lens on how sharp images are even wide open, and how good the IS system works,So after doing same tests my self i can say this is one awesome lens,While shooting i went as low as shutter speed 1/13 at 200mm with the image stabilizer on, And it kept on taking sharp images ..

"Optically speaking this lens is second to none! However even while it is claimed to be of professional quality I have to disagree: It seems that the mechanical parts are not better than any cheap consumer grade lens. I happened to bang this lens against the railing on a ship while turning around.

This compact telephoto lens comes with an Image Stabilizer that compensates for camera shake so you can shoot at up to 4 shutter speed steps slower without blur. The lens optical system uses one fluorite lens element and two UD lens elements to render high-resolution, high-contrast image quality at...
