E-TYPE COMPATIBILITY
Lenses with electromagnetically controlled diaphragms are incompatible with the D1, D2, D40, D40s, D60, D70, D70s, D80, D90, D100, D200, D3000 and D5000.
HYPERFOCAL DISTANCE
Dependent on focal length and aperture, this is the shortest focus setting at which a scene is rendered sharply, right out to an infinite distance.
BUILT-IN HOOD
Ultra-wide lenses tend to have a built-in lens hood, and this can make it difficult or impossible to attach filters, without an additional specialist filter system.
ZOOM RANGe
For wide-angle zoom lenses, the minimum focal length is usually a greater consideration than the size of the zoom range.
APERTURE RATING
A wider aperture rating enables faster shutter speeds in low-light photography, but generally results in a larger, heavier construction.
OPTICAL STABILIZATION
Stabilization is less…
