So Im no liking my 24-105 lens.. everytime I use it less and less, to be honest I cant even remember last time I used it. It just seems that quality wise its not on par with my Tamron 70-200 and 135L, heck I even prefer shooting wide shots with my fuji x100s. I shoot a lot of wedding and environmental portraits and was looking at the Tamron 24-70 VC and the Sigma 35 1.4. My question is have any of you have made the change from 24-105 to the Tamron? Is it worth the change?
