9 out of 10 points and recommendedGreat DOF controlA little slow to focus in low light
When I first opened the box, (january 22, 2010) it was evening and dark out. I tried some low light shots on objects around the kitchen and was very unhappy with the sharpness; especially compared to my Nikon 35mm 1.8. But, when i sued the flash, it was right on. Also, odd enough a few days later, shooting our cat, I was able to use manual and get plenty of brightness sans flash. So, after worrying that it did not focus properly, I have the immpression it needed to be broken in -- I can't explain it otherwise. Or, perhaps I was nervous the first night. Now I am a happy camper because I love the bokeh and that is why I chose it over the Nikon -- plus it tested sharper wide open on several web sites. I have my Nikon 16-85 for more dof and great sharpness. My 35 1.8 is also wonderfully sharp.reviewed February 8th, 2010 (purchased for $500)

It is surprising to see this lens rated only in the 8's on the main page. Between 2.8 and 5.6 this lens is really sharp. I don't know if i got a better copy than some but seeing the number of 10's below, I'd say a bad copy is the exception. For a DX sensor this lens serves as a relatively "normal' lens. I end up carrying it instead of the Sigma 50mm f/1.4 because of its sharpness and utility for low light shooting. (I generally have my 16-85, 70-300, and 12-24 along with one or two SB600's so I can;t bring much more with my current bag and two lens mounted).reviewed May 21st, 2010 (purchased for $200)
I've compared it numerous times with my 16-85VR to see if I can't do as well in low light with the VR on and I cannot. Shoot this guy at 1600 ISO and the regular lighting in a room is just fine.

I've been shooting this lens for a few weeks and have pretty much left it on my second body (I was using a 50-200 or a 70-300 on it). Most people use it for macro but I really got it to extend the range of my Sigma 17-50 f/2.8 OS and it fills in beautifully for most things. Its low light focusing on my D7000 is fast and good. the OS is effective but you should give it a half second to settle. It is sharp at f/2.8 and really tack sharp at f/4 and good all way to f/16.reviewed January 13th, 2014 (purchased for $700)
