Lately I've drawn some interest into adding to my photography repertoire either a fisheye lens or a wide angle lens. Did some research as usual and narrowed it down to a Canon 10-22mm or a Sigma 10-20mm. Luckily a friend of mine owns the Sigma and let me borrow it, and I found myself venturing back out to the lake this past week to play. Given the price point compared to the Canon and the quality I was able to get with the lens, I'm very tempted. At the same time, I'm on the fence about whether or not to save and invest in an L lens that would replace my 28-135mm lens. Decisions decisions.
