One lens that covers most situations. Hard to better and easy on the pocket

Purchased this lens to use as a regular walkabout lens for my Cannon 550D, that covers wide angle to reasonable telephoto.
Well made, light in weight,small in size even at full extent.
Stabilizer facility that really helps in low light conditions.
Have not found any thing I don't like about this lens.
Glad I bought it particularly as I paid in the region of 50% of new retail price.Ebay strikes again!!!

EF-S 18-135

I already had a 17-85 IS and a 28-135 IS so wasn't sure whether or not worth buying this lens but the extra length seemed a good idea although I never got on with the 18-200 IS as a piece of kit.

I'd thought about a 15-85 to go with my 70-200 L-series but not a cheap option and so far I've rarely missed the wider settings; if I need wider I use the 10-22 which is made to do the job of course.

It's mainly used with a 7D but occasionally on a 40D and whatever the pixel or file size I've noticed minimal issues with barrel distortion or corner abberation even at f3.5 and either zoom extreme. If compared to my 100mm f2.8 and blown up to silly size you can just catch a little difference in out and out sharpness but much less than I anticipated.

Close focusing is mediocre but you don't buy a lens like this for macro work and you can't get a decent zoom with IS and Macro for this money so all said this is a very decent walkabout lens for a sensible outlay with a very good 4-stop IS system and without the problems of zoom creep and bulk like the 18-200.

I am happy to recommend this lens for the money

General purpose lens...the perfect companion

Was surprised about negative reviews I read about this lens however took the plunge and went for it....
The image quality is surprisingly good more than pleased was expecting a poorer image. Lens barreling is apparent at full zoom however wideangle distortion is minimal in fact not visable to naked eye especially taking family groups. Was surprised how well the image stability worked...got away with many low shutter speeds just by supporting myself against a wall. In short if you want 1 lens to cover 90% of your photgraphic needs this is it but if you are extremely picky about IQ then buy prime lenses instead at a price

A good all purpose lens and plenty good enough for day to day use.

What a smashing lens!! Giving from a wide angle to telephoto in a lens that is not too big or unwieldy unlike some of the 18-200 that can be bought.

The pictures are crisp and colourful with good definition and although there is some barrel distortion at the wide end, it never became annoying.

The only thing missing from this lens is a zoom lock, to stop the zoom extending as you are walking along, which makes the camera balance awkward.

Other than this- a lovely lens.

Good lens!!!

I was doing a deep research before I bought this lens but have to say that that this lens is definietly worth of money. This lens has great zoom range without compromising neither the wide range nor telephoto range.
