Voigtlander

40mm f/2 SL-IIS Ultron Nikon AIS Black

Prime Lens

Featuring a slender profile and a slightly wider-than-normal focal length, the black-rimmed Ultron 40mm f/2 SL IIS Aspherical from Voigtlander is a versatile prime lens well-suited to everyday shooting. Designed for use with FX-format Nikon F-mount DSLRs, it can also be used with DX models where it will offer a 60mm equivalent focal length. Its slightly wide focal length pairs with a bright f/2 maximum aperture to benefit working with shallow depth of field techniques as well as working in low-light conditions.

The double Gauss-type optical design uses a single aspherical element, as well as ultra-high refractive index glass, to reduce spherical aberrations and distortion for greater sharpness and clarity. The smooth manual focus design permits working with subjects as close as 25cm away with a maximum magnification ration of 1:4, and both depth of field and focus distance scales are featured on the metal lens barrel to aid in pre-focusing or setting hyperfocal distance. A nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.

This lens' physical design also features a scalloped focus ring to recall classic lens designs of the 1960s as well as afford more secure handling during use. Mixing the classic-inspired design with contemporary usage, the lens also sports an AI-S type CPU to permit in-camera adjustment of the aperture setting for faster, more intuitive exposure control.
