Sigma 18-250mm DC HSM vs. Tamron 18-270mm Di II VC LD?
I am very curious to know if anyone has had the opportunity to compare Sigma's 18-250mm walkabout lens against Tamron's 18-270mm?
I'm particularly interested in the comparison of focusing speed and accuracy between the two as I currently own the Sigma 18-250mm (which is an excellent all-in-one, by the way) but do face some issues with focusing especially in low light or when the lighting of subject blends in with the background.
Looking forward to your views.
