Review on Sigma Contemporary Cameras Advanced Travel by Lisa Holland

Well, I'm a cameraman and a photographer. I own my own business and I'm subcontracted to Sony Music, which basically means I'm qualified to make music videos for them. I would give this lens 5 stars if the auto focus was a bit faster and there was also a clicking sound when focusing. So you need an external audio if you want to make audio with it. Sometimes if your f.stop is too high it won't focus and needs some help. I personally don't like this lens because I'm used to it and just shot a whole music video with the i, but that's the only thing that bothers me. I think this is a great lens for photography, you just need to be patient to shoot. Overall, the quality is pretty decent for the price.
