Thanks to everyone on here who gave advice on my recent purchase of a 40D and 70-200mm f/4 L lens, they are quality pieces of kit and great fun to use. The one draw back with the 70-200mm lens is that it is not really suitable for wide angle shots and more 'walk-around' use. I have been looking around and reading this website a lot which I think is excellent: The Digital Picture Looking through there the 17-40mm lens looks a good option. I am on a limited budget but I am prepared to pay for quality kit. I don't want to buy cheap stuff only for it to break in 12 months time. Ideally I would be looking at the 24-70mm f/2.8 lens to fit the gap but that is out of my budget. I know the range is not as big with the 17-40 but I am sure I can live with that. I am also very interested in macro work and my other option would be to get a cheaper 'walk-around' lens and a dedicated macro lens (Canon 100mm macro maybe), I am wondering how effective the 17-40mm is as a stop-gap macro lens, maybe with the addition of an extender? Thanks for all your help. I am off to Rome in a few weeks so I want to grab something before then so I can get some great shots there (and hopefully some better light than this damp grey crap in the UK at the moment!).
