I have looked at that lens, reviews I have seen say it is too soft. Do you own this lens, and, if yes, what has been your experience?
I owned the G2 for a week or so. In bright light it was great. However, I found the A/F was not up to snuff once the was a little dimmer. I retuned it and got a refund.
I must add that I might have had a problematic lens and didn't feel like playing musical lenses. Others here have been very happy with the lens.
