Hi,We've been using this lens for a while now and we're absolutely pleased with its performance. When we decided to get into the extremelly competitive field of wedding/special event photography business we knew we needed a lens that offered us the quality and flexibility to just forget about it and take great pictures. Thus far it has not disappointed us one bit! Great shots at both the wide end and the tele-foto end. Of course, if you are a photophile or professional you might find some nuisances with this great lens. However, for the real-world photography, enthusiasts, amateurs and semi-pro this lens offers a great value. I've recommended this lens to friends and colleagues and will keep doing so until I can find a better price-value choice. A definite must have for everyone with real-world needs (i.e. not uber professionals).
