Mornin',
First of all, I'm completely new to all this so please bear with me! I just bought the above Sigma lens and have a question about the "macro" function.
When I extend the lens to anywhere from 200mm-300mm and throw the switch, no matter how much I try, I can never seen to get the lens to focus properly.
Is there a "trick" to macro photography? Settings on my Rebel XT? Distance away from the subject?
I would appreciate any help!
Kind regards,
Piet
