This lens is praised in my experience too much. It can represent sharp, there is no question, but one must pay attention to it scary despite the high intensity that you're working with very short exposure times. Aperture 1.8 is barely usable in everyday life since the margin range while noticeably lacks sharpness, ie down to a minimum. 4, beser still 5.6 to really exploit the performance potential of this lens can. And then the light conditions have to be very good, otherwise it means that is quickly up on the tripod. Shot out of hand the results of the D300s are not even begin to better than the 18-105 VR with the same focal length. I have the 18-105 has long been extensively tested in use and very many supposedly "better" zoom and prime lenses, a VR-based lens comes so quickly nothing ran, if one has not always been very good lighting available or work with flash want. These sensors (Halbfomat) is the risk of causing camera shake by minimal image blurring, now time for DX very pronounced. The 35er is comparatively well finished, on my copy the visor was shaky and slightly rattled at every touch, for that I find it very unfortunate that it has no distance scale for manual focusing. Could awarded 3.5 stars, I would do that, so it stays in. 3
