Summary: This is a very sharp lens over most of the frame. It is a bit soft in the corners on an FX camera, something that wouldn't even be noticed on a DX camera with a smaller sensor. It might not be noticed in "normal" sized prints and enlargements, 8x12 and under.
Summary: As a prime lens, it is unbelievable. I am now using this more often than my 24x70 zoom. Optics are outstanding. I am now a big fan, regardless of the low price. What a bargain! For weddings, group shots, and landscapes it truly shines.
Summary: After reading a few reviews, I didn't know what to expect. Some say it's a great lens, others were disappointed. So I had to try it myself. Turns out this lens performs very well on a d700 ! Wide open it's very sharp in the center with mild fall-off.
Summary: I wield a Nikorr 70/200 2.8, a 50mm prime 1.8 and this lens. It's everything a hobbyist needs without breaking the bank. This lens is sharp fast and wide enough for most applications that call for a wide angle. I mount this on my Nikon D600 Full Frame.
