To the semi-pros offering advice in this forum. What if I do not wish to use Flash for outdoor picture of boat quay and that bridge there that separates it from Clarke quay? I took some at high ISO recently, and they came okay, but when you see it at 100% resolution on a big 24 inch monitor imac, the lines of the bridge are blurred. I think the solution is a tripod, not a lens. Even the basic 18-200mm can take excellent, sharp photos but a tripod is a must, because even with VR and a very patient meditative posture for shooting, there is ALWAYS some blur. For night photo, get a tripod. Get a tripod. Did I mention, get a tripod.
