Focussing problems with Sigma 10-20mm f3.5
Hello all
My first thread!
I have been using my Sigma 10-20mm f3.5 for about a month now (mounted on a Canon 60D) and it was all working fine. But I recently encountered a strange problem when using the AF. The lens wont focus to infinity when I use the LCD display resulting in a blurred image. However, there doesnt seem to be a problem with the AF when the viewfinder is used. This seems to be case for all three focussing modes (live mode, 'L' live mode and Quick mode).
So could any advise me on what to do.
Thank you
