I am at a cross roads. I own a Nikon D40X, I have the stock 18-55 lens and a Nikon 55-200 AF-S lens, frankly I am tired of changing lenses during our family outings, it seems I always have the wrong one on. I would also like more zoom. I am looking at the Tamron AF18-270 F/3.5-6.3 Di II VC LD Aspherical (IF) Macro. I shot a buddies Tamron and liked it for the money they seem like they can't be beat.
