I found the 24-105L's range pretty good for walk around on my crop, but the f/4 was killing me. By combining a Sigma 30mm f/1.4 with my 100L, I cover the 2 focal lengths that I used the lens at anyway, but with much more flexibility due to larger aperture. The Sigma 30mm f/1.4 is fantastic for indoor, outdoor, PERFECT for hiking due to it's compact size and weight, landscapes, portraits, etc. I found the 24-105L limiting and have absolutely NO regrets on the replacement. The 24-105L is overrated IMO, although the build quality is fantastic.
Anyone have similar experiences to share?
