The Ultron 28mm/f2 is the replacement model for the popular Ultron 28mm/f1.9 Thread Mount. Though the new lens is slightly slower, it’s smaller in size and handles beautifully on the rangefinder body.
With the 10 lens elements in 8 groups and 10 aperture blades, the Ultron gives a viewing picture angle of 75 degrees in 35mm format, it’s perfect for indoor wide angle shot and a general walk about lens on the Bessa & Leica bodies.
With the large aperture, the 28mm gives a very pleasing and smooth bokeh when shot wide open, which is normally difficult to achieve on wide angle lenses.
