Quote:16-85 will indeed put my FL in one lens, but I found out that IQ more or less is the same with my current lens at the cost of $200++, I don't think it worth itHm, as I said IQ-wise you will gain hardly anything apart from less vignetting with a 24-70 over your 18-105 which is quite a sharp lens. The Sigma will probably even be worse than your 18-105 while the Tamron will be more or less be the same (may be a tad sharper, but hardly anything you will notice in practice). You dont sound like you need the f/2.8 aperture either, so I would recommend you stick with your current setup. It is very good.
