Got a Sigma 105-2.8 ex/dg lens, tried it yesterday, could not make it focus on anything other than a flower about 4 in. in dia, did not know what limit or full was so I called Sigma and the lady read me something she didn`t understand nor I.I tried manual and auto modes on camera, still didn`t get any better. There is no way that I could have focused on something small as a bee.Please tell me what i`m doing wrong .
Many thanks for any help !

George

What is your focus limiter switch set to?

This might help with an explanation:

I agree. It sounds like your focus limiter switch is set to close range only. If you "limit" the focus it can only focus on things close to you. That's great if you want to get a shot of a bug or flower or something that is very close. If you set it to "full" then it can focus all the way out to infinity. that's good for everything else.

Setting it to "limit" will help it focus faster when you are working at close range, so it's good to use that in some cases. But in general, for portraits or whatever, you will want to sue "full" instead.

good luck!
