Really Good Photos and they bring back memories of my visit to Prague. I am thinking of trading in some of my kit to buy Canon 24-105mm f/4 IS USM. as I am getting old now and my grip is not as good as it us to be so as an all round lens I have desided to buy. would appreciate your oppinion of the lens as I have read other reviews. My wife and I loved Prague and we might return there again but not in Nov but in the summer time.
