I love this lens. Extremely sharp, compact, cheap, great colors, fast and quiet autofocus, and most importantly a great focal length for a walk around every day lens. Simply the best lens choice for the D3100 in the prime category. This lens will be on my camera 95% of the time.
I bought the lens from A.A.B. Photography in City Center Salmiya. They sell it for 82 KD and bring it direct from Nikon. It took five days to get to them and as soon as it did they called me right away. Great service and people.
