Voigtländer Ultron 40mm f/2 SL IIS Aspherical Lens for Nikon F (Black Rim)

Slightly wider-than-normal prime, this 40mm f/2 lens is designed for FX-format Nikon F-mount DSLRs, however can also be used with DX models where it will provide a 60mm equivalent focal length.

Bright f/2 maximum aperture benefits working in difficult lighting conditions and also affords greater control over depth of field when using selective focus techniques.

Double Gauss-type optical design uses ultra-high refractive index glass and incorporates one double-sided aspherical element to reduce spherical aberrations and distortion for greater sharpness and clarity.

Manual focus design permits working with subjects as close as 9.8" away with a maximum magnification ratio of 1:4.

Nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.

All-metal lens barrel integrates both focus distance and depth of field scales to aid in using pre-focusing and hyperfocal focusing techniques.

Scalloped focus ring and smooth focusing action affords precise control when handling.

Built-in CPU permits using in-camera controls for adjusting the lens' aperture setting.
