APO-ULTRON 90mm F2
Features
The new design APO-Ultron VM 90mm F2 offers very high optical performance in a small compact lens that extends only 63.3mm from the lens mount. The apochromatic design reduces axial chromatic aberration close to zero. The lens does not protrude into the viewfinder frame, and has excellent portability.
Main Features
Apochromatic design
The apochromatic design that makes the on-axis chromatic aberration of RGB, as close to zero as possible.
High performance & compactness
The newly designed optical system uses abnormal partial dispersion glass for 6 out of 8 elements in 7 groups. The compact lens design is only 63.3mm long.
12-blade aperture diaphragm for beautiful bokeh
The aperture diaphragm is configured with 12 blades to make the aperture opening as circular as possible. This means the out-of-focus areas of images are drawn naturally and point light sources etc. are drawn as soft round bokeh rather than as polygonal shapes.
Comes with a special metal hood
The attached metal hood has a bayonet-type fitting that can be mounted in reverse when stored or carried.
Manual focus that enables reliable focus operation
By adopting an all-metal helicoid unit processed and adjusted with high precision and high-quality grease that produces an appropriate torque, focusing with a smooth operation feeling and delicate focus adjustment is realized.
With careful experienced design the focusing action is smooth and precise.
Bayonet type VM mount
The VM mount is compatible with the M lens mount.
Equipped with a rangefinder interlocking system
The high-precision rangefinder focusing enables precise focusing wide open
Full-frame image circle
A generous image circle that supports full-frame 35mm format is secured. In addition, it achieves a very compact style compared to interchangeable lenses for SLR cameras.
