Here's your EF-S lens list but with the aperture etc. included and my own very personal opinions added:
- EF-S 10-22mm f/3.5-4.5 USM - gives cropped sensor owners a decent wide-angle lens albeit with significant vignetting wide open
- EF-S 17-55mm f/2.8 IS USM - probably the nearest that EF-S lenses get to an "L" model but also suffers from vignetting wide open
- EF-S 17-85mm f/4-5.6 IS USM - decent but not great upgrade to the kit lens
- EF-S 18-55mm f/3.5-5.6 IS - the kit lens in Europe
- EF-S 60mm f/2.8 Macro USM - a very nice macro lens for cropped sensors
- EF-S 55-250mm f/4-5.6 IS - no tests yet but has a micro motor AF system
I have left out the EF-S 18-55mm f/3.5-5.6 as the IS version effectively supersedes it.
Despite owning a cropped sensor Canon camera this list really doesn't bowl me over. The 10-22mm is the only Canon choice if you need significant wide-angle zoom capability on a cropped sensor so they really had to offer it. The 17-55mm f/2.8 is a decent alternative for, and similar in price to, the EF 24-105mm f/4L IS USM; which you choose depends on the value you attach to 17mm and f/2.8 compared to 105mm and f/4. As for the kit lenses, well, kit lenses are kit lenses - 'nuff said. The 60mm macro is good to have - tick, vg. As for the 55-250mm telephoto zoom, optically it may be wonderful (we'll have to wait and see) but the fact that Canon can't even see it's way to including a USM focus motor astonishes me. Hardly a ringing endorsement of its commitment to high end lenses for cropped sensor bodies.
OK - I admit it. I have been a little naughty and provocative (
) but only to try and demonstrate that Canon is not really showing much sign of shifting its focus (
- sorry) away from EF glass. That doesn't mean I believe that the 40D replacement will have an APS-H sensor (1.3x FOVCF), exciting as that would be, but maybe Canon are
keeping their options open for the next decade.
