Product Summary
Limited to 660 individually numbered examples, this Classic Line release brings an unusual piece of Leitz Canada history to current M-System photographers. Its optical design takes inspiration from the original ELCAN 66mm f/2 but has been optimised for modern rangefinder cameras. Distinctive details include the reverse-turning aperture ring, military-style distance scale and period-inspired engravings have been retained.
At maximum aperture it creates soft bokeh and high contrast, with resolution increasing when stopped down for fine detail. The 66mm focal length also provides a unique perspective between the more familiar 50mm and 75mm choices in the M range.
Backstory
A rare commission from Leitz Canada
Dr. Walter Mandler developed the ELCAN 66mm f/2 at Ernst Leitz Canada during the late 1960s for use by the US Navy. According to Mandler, the requirement was for an optic that appeared unremarkable while delivering an exceptional level of resolution. The unusual focal length resulted from balancing resolving power, fine contrast and compact dimensions. Around 200 were produced, and surviving examples are now among the rarer M-mount optics from this period.
Reinterpreted rather than reproduced
The modern version uses a design based on its predecessor but optimised and adapted to current manufacturing standards. Some of the original’s unusual handling characteristics are deliberately preserved. The aperture control turns in the opposite direction to standard M models, while the metre and feet markings are inverted compared with the conventional arrangement.
The front ring carries the optical calculation number B1047 alongside an individual edition number and 12-digit internal material number. Engraving details also reference the historic design.
Two sides to its rendering
At f/2, Leica describes the image character as combining soft, creamy bokeh with high contrast. Stopping down shifts the emphasis towards the quality central to the original military application. That means high resolution and clearly reproduced fine detail. The nine-blade diaphragm also creates polygonal highlights at intermediate half-stop settings.

Frequently Asked Questions
Will it work with digital and film M cameras?
It uses the M bayonet and is compatible with suitable digital and film M-System rangefinder cameras.
How does 66mm compare with 50mm and 75mm?
It provides tighter framing than 50mm without the narrower view of 75mm, offering an interesting middle ground for portraits, details and more selective compositions.
Do the unusual aperture and distance markings affect handling?
Yes. The aperture control turns in the opposite direction to standard M models, while the metre and feet scales are inverted, so existing users may need some time to become accustomed to the different operation.
