Key Features
Fast and compact, the 50mm f/1.4 ASPH. from TTArtisan is a versatile normal-length lens for Leica M-mount rangefinder cameras. Its bright design suits working in difficult lighting conditions and also affords improved control over depth of field for working with selective focus techniques. The lens also sports an advanced optical design, which uses a series of specialized elements to reduce various aberrations and distortion in order to achieve high sharpness and accurate rendering. The lens's manual focus design permits working with subjects as close as 2.3' away and it features a 12-blade diaphragm that contributes to a smooth bokeh quality.
Normal-length prime is well-suited to everyday shooting with subjects including portraiture, street, landscape, and reportage.
Impressively fast f/1.4 maximum aperture suits working in low-light conditions and also offers enhanced control over depth of field for isolating subject matter using selective focus techniques.
One aspherical element and eight high refractive index elements help to suppress distortion and spherical aberrations in order to produce accurately rendered images with a high degree of sharpness.
One abnormal dispersion element reduces color fringing and chromatic aberrations in order to realize high clarity and accurate color rendering.
Manual focus design permits smooth, refined control along with a minimum focusing distance of 2.3'.
A 12-blade diaphragm contributes to a smooth and pleasing bokeh quality.
