EF-S 18-135mm f/3.5-5.6 IS USM
3-4 Stops IS
Full Time Manual Focus
Minimum Focus Range of 20” or Less
I'm no mathematician and don't know if it is even possible to create such a lens, but it could be close to this; say 18-105 or 18-120 or whatever. After using Nikon's 18-200 VR I have been trying to find something similar for Canon's with no luck. The 28-300mm f/3.5-5.6L IS USM comes darn close, but -10mm, 5 ½ pounds, a minimum focus distance of 2.3 feet and costing $2200 is just too much of a compromise – it simply wasn't made for cropped sensors. Sigma's 18-200 OS would have been perfect, but the 6.3 aperture and so-so IQ again just doesn't match what I want. The Canon EF-S 17-85MM f4-5.6 IS USM doesn't have a far enough zoom, IQ is lacking on the low/high end, allot of distortion at the low end and noticeable pincushion effect and I don't like the build quality – all apparent in its low cost. I know everything has compromises, but Canon doesn't seem to really take cropped bodies very seriously thus their lack of EF-S L lenses. I guess I have to buy a 5D to get Canon's better lenses.
I didn't want to like the Nikon lens, but with 3+ stops VR (with proper holding techniques I've gone lower) and all the right compromises it was a loosing battle.
Sorry, rant over.
