i've just got my sigma 70-300mm. i'm hoping to take macro shots with it and i've done alittle playing around with the lens.
i'm thinking of shortening the min focusing distance. i know one cheap way around it would be using close up lenses. i'm thinking of getting a cheap +2 or +4 close up to try it to see how it works out
the sigma focuses to 1.5m on normal mode and up to 0.95m on macro mode. if i were to use a +2 or a +4 closeup, how much close can i get?
