This lens is incredible!
Canon 7D, and 15 ~ 85 mm kit is what I use it for. However, some four months later, was frustrated by a very bright tone. I stress that the sound you hear, but also catch up with Canon and Nikon lenses also considered that the cause of the problem. I compensated for the loss of quality special filters to buy, though, but a few ways to do this will be difficult to use the camera decided not to work. However, even if the exposure is not the way I want, adjust the photo shoot, the data is simply too much or too dark, some of the pictures, because it does not exist, the balance was not the brightest.
Sigma 17-50mm f/2.8 lens, so I decide to buy this, and I could not believe my eyes. When I arrived, I compared the two lenses through your window and take some photographs of clouds and brilliant tone, if you know the difference, I sent them to the computer after you compare the quality of Canon lenses is not allowed. Sigma is much more saturated colors, and much more information had been. This advantage (zoom, etc), but the quality of glass is a big difference with this is fair because the Canon and Sigma 1915-1985 can not be compared, I understand. Do not get me started focusing ... It is very sharp! Operating System, AF, big hole, but also a huge advantage.
My copy only to find the problem, if not use if you shake hands, rattle, and when something in the camera. This is a very small voice that gave her does not affect performance, but I was not worried. I'm back, but new, but the two are not identical copies. It can be overreacting, but people will notice this too?
You can see more than a matter of past BTW, if you build on this lens is quite powerful.
various environments (natural, etc.) After taking about 1000 photos, I can not recommend this.
And one more thing: I am the 1917-1950 attempt to venture to the store Tamron, AF, and very disappointed. I also have Canon glass, bright colors and the quality is very similar also found that exposure to bother me.
I highly recommend the lens!
