Nikon AF-S Dx 12-24mm Lens/F4g If Ed Lens
The Nikkor AF-S 12-24mm f/4G IF-ED DX is the current native ultra-wide zoom lens option for APS-C Nikon DSLRs. On the D200 (used for testing) its field-of-view is equivalent to 18-36mm on classic camera and as such it is obviously a highly interesting option for landscape photography or other applications with the need for an extra kick in perspective.
The build quality of the lens is very decent. However, the outer parts are still just made of (good quality) plastic - slightly disappointing for a lens in this price class but positively speaking it is a very light-weight lens as a result. The broad, rubberized zoom and focus rings operate very smooth. The physical length of the lens remains constant despite a moving inner lens tube. Thanks to Internal Focusing (IF) the front element does not rotate so using a polarizer remains easily possible - even with the supplied petal shaped hood. Like most recently released Nikkors it is a G-type design without a dedicated aperture ring. The Nikkor has an internal, silent-wave (ultrasonic) AF motor which operates both fast as well as near-silent.
