Voigtlander's updated Ultron 28mm for M — the MK II with improved digital correction.
The Voigtlander 28mm f/2 Aspherical MK II VM is a fast wide-angle prime from Voigtlander in VM (Voigtlander M) configuration for Leica M mount, the second-generation revision featuring improved aspherical element correction. The f/2 maximum aperture makes it one of the fastest 28mm lenses available for the M system.
The lens delivers 28mm at f/2 maximum aperture with aspherical optical elements for reduced coma and spherical aberration at wide apertures, Leica M bayonet with 6-bit coding, manual focus and aperture, and full-frame coverage.
The 28mm f/2 is a popular focal length and aperture combination for documentary, street, and available-light photography on Leica M bodies. The MK II revision improves on the original's wide-aperture performance with better aspherical correction. At its price it provides f/2 wide-angle performance for the M system at a fraction of Leica's own 28mm lenses.
Test rangefinder coupling accuracy at close focus distances — aspherical 28mm designs can show coupling challenges at minimum focus. Verify 6-bit coding recognition. Inspect aspherical element coating. Check aperture blade operation at f/2. Test corner sharpness on a full-frame sensor at wide apertures.
