Light Lens Lab 50mm f/2 ELCAN

Light Lens Lab 50mm f/2 ELCAN

This lens is an affordable reproduction of one of the rarest Leica optics ever made: the 50mm ELCAN built for the United States military to accompany the KE-7A camera. The original was produced in tiny numbers by Ernst Leitz Canada, and complete lens-and-camera sets now command roughly $30,000, a price driven almost entirely by scarcity rather than photographic utility [1][2]. Light Lens Lab, a brand that designs in Canada and manufactures in China, set out to recreate that lens at a fraction of the cost, allowing photographers to use the unusual ELCAN optical character without paying collector prices[3]. The name ELCAN derives from Ernst Leitz Canada, the Midland, Ontario operation that became a major lens-design center under Walter Mandler, the designer behind the 50mm Noctilux f/1 and the Summicron-M 50mm f/2.

The optical formula is a compact four-element, four-group design, and the result is one of the smallest 50mm f/2 lenses available for the Leica rangefinder system, excluding collapsible designs. At 26 mm long and 227 g, it produces no rangefinder blockage and brings up the 50/75 mm frameline set. The lens focuses to 0.7 m, with a focus ring that turns roughly 180 degrees from minimum distance to infinity and carries a focus tab. Its aperture, controlled by ten blades, is operated through a small tab rather than a conventional ridged ring, and the ring offers half-stop clicks. The thread mount and rangefinder coupling make it compatible with screw-mount bodies and, via adapter, with M-mount cameras. The filter thread is a standard 39 mm (E39), so common filters fit without special accessories.

Light Lens Lab offered the lens in several finishes, including chrome, black paint, black paint with brassing, safari, bare brass, and a titanium version, with most bodies built in solid brass. The barrel is engraved as made in China. One trait carried over from the original is unusual for Leica users: the aperture scale runs in the reverse direction, reading from f/16 to f/2 left to right rather than the customary f/2 to f/16. Prices were reported around $800 to $900 in some accounts and higher, from roughly $1,500 upward, in others, with the titanium version the most expensive.

Optical qualities

Rendering The lens has a distinctive look rooted in its military origins, where a sturdy, small, low-cost design likely mattered more than pleasing out-of-focus rendering. Reviewers describe high contrast and strong central resolution paired with a marked falloff toward the corners, a combination often summarized as a vintage character that suits this lens well.

Sharpness Center sharpness is high with strong contrast wide open, but MTF behavior shows a noticeable midzone dip and weaker corners at f/2. Stopping down improves most of the frame, though the extreme corners remain comparatively soft. The lens also shows pronounced focus shift, particularly between f/2.8 and f/4, so reviewers advise caution using the f/4 setting when relying on the rangefinder.

Bokeh and transitions At close distances the center renders out-of-focus highlights smoothly with evenly lit discs, but toward the corners those highlights deform and show strong outlining, producing busier backgrounds.

Distortion and vignetting Distortion is low but not perfectly uniform, mostly absent across the frame yet visible on straight lines near the edges. Vignetting measured about 2.6 EV at f/2, easing to roughly 1.0 EV by f/8, figures one reviewer found modest given the lens's small size.

Flare resistance As a replica of a vintage formula, flare resistance is not a strong point, in line with expectations for this kind of design.

Aberrations Lateral chromatic aberration is minor and easily corrected in post processing.

History

Development and Launch The original ELCAN 50mm f/2 was the standard lens for the Leica KE-7A, a militarized version of the M4 built for the American Army, with lens and camera produced at the Ernst Leitz Canada plant during the early 1970s. Only a small number were made, commonly cited as around 500, which underpins the original's rarity and high prices today. The original used specialized glass and was engineered for ruggedness, including gaskets intended to help the optics survive shock. Light Lens Lab released its replica in 2021, following an earlier Summicron v1 reproduction, to make the ELCAN's look accessible to ordinary photographers.

Special editions Rather than a single configuration, the LLL ELCAN was offered across multiple finishes including chrome, black paint, black paint with brassing, safari, bare brass, and a titanium variant, the last positioned as the premium option.

Collector Notes Buyers should not confuse this modern reproduction with the original Leitz Canada ELCAN, which is far rarer and more valuable. The replica is engraved as made in China and carries the reversed aperture scale of the original, a useful identification cue. The lens uses standard E39 filters, and reviewers note no lens hood was necessarily included with review samples, so a hood is an accessory worth confirming before purchase. Sources differ on the launch price, citing figures from roughly $800 to well over $1,500 depending on finish and timing, so confirm current pricing and the specific finish when buying.
