For those of you who have been following the thread on the Fab Four I have all but decided to get the Sigma 20MM f/1.8 EX DG Aspherical RF as my "anchor" lens. This will give me an effective 32MM for those wide indoor shots
Now my question is does anyone have experience with this particular lens? This will be my first lens outside the Canon family and I have no experience with the Sigma line of lenses.
The 20MM f/1.8 gets good reviews and I like the photos I see made with it on pbase. Are there any cautions or warnings I need to be aware of?
