The ULTRON 75mm F1.9 VM is a manual focus medium telephoto lens optimized for full-frame M mount sensors. The newly designed optics consists of 7 elements in 5 groups, 3 of which are made of cutting-edge partial-dispersion glass technology, which both suppresses chromatic aberration and ensures high image quality.
The balance between bokeh and resolution has been optimized by deliberately leaving a moderate amount of spherical aberration. While maintaining the clarity of the image areas which are in focus, the out-of focus area produces a rich and large bokeh effect.
The new but simple construction allows all the elements to move in tandem, resulting in an overall length of only 54.1 mm, which is extremely compact for a 75mm lens. The lens thus offers excellent portability and also suppresses vignetting in the frame when used on rangefinder cameras.
This lens is equipped with a high-precision rangefinder-coupled mechanism, and the full-metal helicoid ring provides a silky smooth luxurious focus-feel and the true pleasure of focusing on a film or digital rangefinder camera.
The minimum focusing distance is 0.5m, allowing extremely close focus, beyond even many rangefinder mechanically-linked focus-ranges.
