I think it's my best lens yet. It worked like a charm with the D7000. I believe there's some softness when it's fully open, but very sharp pictures at f/1.8 and above. So it's been very good for poor light conditions.

Edit: Still love this lens. Now it pairs with the D750 for low light pictures. Works great. The focus is a bit slow now that I've tested other lens and sometimes it feels like closest focus distance is too far (but that's because I've been trying to take pictures of babies crawling towards me :-)
