I purchased this lens around one year ago and haven't regretted my decision. It is a prime lens so you cannot zoom with it. That being said, it gives you amazing clarity and works really well in low-light conditions. If you are looking for a lens that gives you a blurred background on a portrait you have come to the right place. I originally had the 1.8 but decided to upgrade to the 1.4 when I switched from Canon to Nikon. The 1.8 works really well and is at a great price but if you want to take the step up this is a good lens to get. I have found that shooting at a 2.8 for a single person portrait allows me to get plenty of light into the camera but gives me a beautiful background as well. It will work well as a standard lens on your camera but if you are looking to be far away from your subject and zoom in you will not be able to accomplish that. Another point to make about this lens is that you need to make sure you actually focus on the subject and not something in the foreground or you will get a totally blurred subject.
