I’m fickle when it comes to lens selection.
I’ve been using the EF 17-40mm f/4 L USM as my primary landscape lens for quite some time, even though it’s really a 27-64mm lens on my 40D’s APS-C size sensor. I really like the “feel” of this lens on my 40D. It’s not too heavy nor too large. The build quality is superb and the USM auto-focus is lightning fast. This lens is incredibly sharp at any aperture in my experience.
I also like the “value” that this lens provides. At $670 (USD), this lens is a steal and holds it’s resale value extremely well. This is also one of the least expensive “L-Series” lenses that Canon makes. Given all this I never thought I’d regret my decision to purchase this lens.
But all that changed when I rented the EF-S 10-22mm f/3.5-4.5 USM lens to see what a real wide-angle zoom was like on the 40D.
All I can say is WOW!
If you could pick up each lens while blindfolded you might be able to better understand my feelings.
The EF-S 10-22mm f/3.5-4.5 USM lens looks, feels and performs just like it’s more expensive “cousins” the EF 17-40mm f/4 L USM and the EF 16-35mm f/2.8 L II USM lenses.
It is tack-sharp throughout it’s entire aperture range (f/3.5 – f/22) as far as I can tell, and the color depth and image contrast it produces is incredible.
And talk about wide! Most of us using APS-C size sensors have no idea what shooting with a true ultra-wide angle lens is like. This lens finally lets us really “go wide” in our landscape work.
At $700 (USD) it’s the same price as the 17-40mm f/4 L and half the price of the 16-35mm f/2.8 L. For anyone shooting with an APS-C sensor, this is your wide-angle zoom. Don’t let the lack of a red stripe, lens hood and bag fool you. The EF-S 10-22mm f/3.5-4.5 USM is an “L-Series” lens in disguise.
