dock

Hi all I have the Sigma 18-300 and I love the lens, but i'm confused with the software which we can use. What settings does everyone have on the lens to get the best results out of the lens? It is being used on a Nikon D5300

Got my new Sigma 18-35/F1.8 DC today and it didn't take long to notice that the AF was off. Luckily I have the Sigma USB Dock and I have started calibrating it (which is quite tedious), I have a few focal lengths at infinty left to do but the day light is fading. Anyway, AF is atleast, or near...
