You should check with Jack Davis for sample shots with the 55-300. It seems to be a much better lens than I would have thought.
I can tell you that unless you are prepared to spend some big bucks, you are not going to get any better than this one at the 300+ end. You really need to decide whether the difference in weight is going to be an issue for you. The 55-300 is more versatile with more reach. I think either choice is good - better than what you have now. -- Best regards, Bruce Tuesday, June 8, 2010, 6:53:27 PM, you wrote: EK> I'm in the market for a new lens and looking for sage advice from the list.
