Let's get straight to the point that this is obviously a VERY commercial goal, bordering on gift, having said that I was pleasantly surprised by this. The construction is plastic but sturdy, when you hold it in your hand it looks like a toy (and therefore it weighs little and is very important for those who carry a lot of lenses), but... if you Once it's assembled, you'll find that the autofocus works quite well, the brightness is spectacular and there aren't any bad photos even at full aperture. The focal length is great as a full frame all rounder and perfect for portraits on APSC, the blur is nice and unless you're a pro you won't notice the difference to the Nikon which costs at least 4x. Once you've developed the photos, you'll notice that when it's wide open, it's a little soft, especially around the edges, but when you close it a few stops, it becomes a blade. In summary it is a real best buy, certainly not the best lens in the world but if you want to try the lens it will not disappoint and you might also find that you are selling the Nikon and using it for that keep less weight. I also have a 50mm older brother but in my opinion this one performs better.
