There’s no such thing as a free lunch in lens land and the Sigma AF 18-200mm f/3.5-6.3 DC is no exception here. The resolution figures are generally quite decent and regarding the extreme zoom range you may accept the very pronounced distortions present throughout the zoom range as well as a few other shortcomings. Unfortunately the AF accuracy leaves something to be desired with this lens especially towards the long end of the zoom range. Typically such a type of lens is used by beginners on entry level DSLRs where a rather dark viewfinder combined and an average AF system don’t really help here. So if you’re interested in this lens it’s a good idea to take your DSLR to your trusted photo dealer around the corner to check whether the camera’s AF system is really up to the task. If so it is a good compromise between quality and zoom range. READ FULL REVIEW
