What lens would you recommend for the Canon EOS 40D to be used for Landscape/Fall Foliage photos?
I use two lenses with Canon 20D. Canon EF-S 17-85mm f/4-5.6 Image Stabilized lens. With Canon 40D it would work as 27 – 135mm (Canon bodies have crop factor 1.6). It covers from wide angle to low telephoto (135mm). Very convenient for travel and outdoor. However, this lens will overlap your lens (45 – 216mm with 1.6 crop factor). Canon EF 70-300mm f/4-5.6 Image Stabilized lens. With Canon 40D it would work as 112 – 480mm. So, this combination covers pretty wide range (from 28 to 480mm), which is very convenient for travel, outdoor, landscape and other situations. My main lens (80% of time) is 17-85mm. Your lens (28 – 135mm) with Canon 40D would work as 45 – 215mm. If you want to extend to wide angle side, check Canon EF 18-55mm (27-85mm with Canon 40D). It’s not expansive lens (~$140) wouldn’t dramatically overlap your current lens. For telephoto option you could try Canon 100-400mm (160 – 640mm with Canon 40D). It’s pretty expansive however. Suggestion: try as much as possible you cur
