I’m considering swapping my Canon EF-S 18-135mm for a lens with more zoom for my EOS 50D. I’ve read recommendations for the Canon EF-S 18-200mm f/3.5-5.6 IS and the Sigma 18-250mm f/3.5-6.3 DC. Could you highlight any key differences between these two lenses? Are there any standout features that make one better than the other? Or do you have any other recommendations?
