Canon 35mm f/2.8 II

Canon 35mm f/2.8 II LTM

The Canon 35mm f/2.8 II LTM is a compact wide-angle lens for Leica screw-mount rangefinder cameras. It was marketed by Canon in January 1957 and belongs to Canon’s postwar rangefinder lens system for Leica-thread-mount bodies, including Canon, Leica, Nicca and other L39 cameras. Canon’s own Camera Museum lists the lens as a 35mm f/2.8 lens with 6 elements in 4 groups, 1m closest focusing distance, 40mm filter diameter, 48 x 30.2mm dimensions and 125g weight .

This entry covers the later Canon-branded 35mm f/2.8 II, not the earlier Serenar 35mm f/2.8 I. The earlier 1951 Serenar version is also a 6 element, 4 group 35mm f/2.8 LTM lens, but Canon lists it with a 34mm filter diameter, 48 x 25.5mm dimensions and 165g weight. Because those specifications differ materially, the 1951 Serenar 35mm f/2.8 I and the 1957 Canon 35mm f/2.8 II should be treated as separate entries or clearly marked variants .

The Canon 35mm f/2.8 II is a rangefinder-coupled L39 / LTM lens with manual aperture and manual focusing. It is often valued as a compact alternative to faster Canon 35mm LTM lenses such as the 35mm f/1.8 and 35mm f/2. Collector descriptions usually place it in the practical user-lens category rather than the ultra-rare category, but clean examples with original finder, hood, caps and case remain desirable for Canon rangefinder collectors .

Optical qualities

Rendering

The Canon 35mm f/2.8 II uses a 6 element, 4 group optical formula. Filmosaur describes the Canon 35mm f/2.8 LTM as a Planar-type design with good across-frame sharpness and minimal distortion, while also noting that some users describe it as high-resolution but lower contrast. This is user-level observation rather than formal optical bench data.

Sharpness

Available user reports generally describe the lens as sharp enough for regular rangefinder use, especially stopped down. Filmosaur found it fairly sharp across the frame, while Rangefinderforum discussion places the 35mm f/2.8 below the faster Canon 35mm f/2 at the edges but still usable as a compact 35mm option .

Contrast and color

The lens should not be described as a modern high-contrast optic. User reports often present it as a vintage Canon LTM lens with good resolution but more modest contrast than later multicoated lenses. Contrast also depends strongly on haze, cleaning marks and coating condition .

Distortion and vignetting

Distortion is generally reported as low for a vintage 35mm rangefinder lens. Filmosaur specifically notes minimal distortion. Stronger claims about exact distortion percentage or corner illumination should be avoided unless measured from the specific copy.

Digital use

The lens can be used on Leica M cameras with a standard L39-to-M adapter and on mirrorless cameras with suitable adapters. As with other vintage LTM lenses, rangefinder calibration, adapter accuracy and optical condition matter. Internal haze or cleaning marks can reduce contrast more noticeably on digital bodies than on film.

History

Development and Launch

Canon produced several 35mm Leica-thread-mount lenses during the rangefinder era. The earlier Serenar 35mm f/2.8 I was marketed in October 1951, while the later Canon 35mm f/2.8 II was marketed in January 1957. The II version arrived in the same broader period as Canon’s more advanced rangefinder bodies and faster Canon wide-angle lenses.

Production Evolution

The main evolution is the shift from the earlier Serenar 35mm f/2.8 I to the later Canon 35mm f/2.8 II. Canon’s official specifications show the same 6 element, 4 group optical count and 1m closest focusing distance, but the later II version uses a 40mm filter thread, is longer at 30.2mm, and is lighter at 125g. The earlier Serenar version uses a 34mm filter thread, is listed at 25.5mm long, and weighs 165g.

Special Editions/Variants

No confirmed commemorative factory special edition is widely documented for the Canon 35mm f/2.8 II LTM. Collector-relevant variants are mainly the earlier Serenar 35mm f/2.8 I, the later Canon 35mm f/2.8 II, accessory differences, and condition or completeness differences. Original Canon 35mm finders, cases, hoods and caps add collector value.

Collector Notes

Collectors should verify whether the lens is the 1951 Serenar 35mm f/2.8 I or the 1957 Canon 35mm f/2.8 II. The filter size is one of the easiest checks: the earlier Serenar version is listed by Canon with a 34mm filter thread, while the later Canon II version is listed with a 40mm filter thread. Important condition checks include haze, cleaning marks, coating damage, aperture oil, smooth focusing, infinity focus, rangefinder coupling accuracy and whether the lens includes the correct finder, hood, caps and case.
