Lens Overview — Canon 28mm f/3.5

The Canon 28mm f/3.5 is a prime wide-angle lens built for Canon rangefinder cameras, mounting via the Canon Screw Mount. Designed for full-frame coverage, it delivers a 28mm focal length that suits a range of photographic subjects where a wider perspective is desirable. With a maximum aperture of f/3.5, the lens offers a moderate light-gathering capability in a package that weighs just 200g, making it notably compact and easy to carry for extended shooting sessions.

Focus is entirely manual, which is in keeping with the rangefinder shooting experience and encourages deliberate, considered composition. The 40.5mm filter thread size allows for the use of standard filters without adding significant bulk to the front of the lens. There is no image stabilization, which is typical for lenses designed around the rangefinder system.

As a prime lens with a fixed 28mm focal length, it encourages photographers to work with their feet and think carefully about framing. The Canon Screw Mount connection means compatibility is specific to cameras accepting that mount, so buyers should verify their camera body before purchasing. Overall, this is a lightweight, manual-focus wide-angle prime suited to the rangefinder workflow.

Key Features — Canon 28mm f/3.5

28mm Full-Frame Prime: Fixed 28mm focal length provides a genuine wide-angle perspective suitable for street, travel, and environmental photography on full-frame rangefinder bodies.

f/3.5 Maximum Aperture: Moderate light-gathering capability for a lens of this era and size, usable in a range of lighting conditions.

Canon Screw Mount: Mounts via the Canon Screw Mount (a proprietary thread mount used on Canon rangefinder bodies, distinct from the Leica Thread Mount / M39 despite physical similarity).

Manual Focus Only: Fully manual focus operation suits the deliberate, considered shooting style inherent to rangefinder photography.

Compact 200g Build: At just 200g, the lens is light enough for extended handheld shooting without adding noticeable bulk to a rangefinder kit.

40.5mm Filter Thread: Small filter thread size keeps compatible filters affordable and easy to source while adding minimal weight to the front of the lens.

Description — Canon 28mm f/3.5

The Canon 28mm f/3.5 Rangefinder is a prime wide-angle lens designed for full-frame rangefinder cameras using the Canon Screw Mount. Its fixed 28mm focal length places it firmly in wide-angle territory, well suited to subjects that benefit from a broader field of view. The maximum aperture of f/3.5 provides a moderate level of light gathering, and the lens is focused entirely by manual means — fitting naturally into the rangefinder shooting workflow.

Weighing just 200g, it is a genuinely compact and portable option that won't weigh down a camera bag. The 40.5mm filter thread allows photographers to easily attach standard filters for creative or protective use. With no image stabilization, steady technique is important when shooting at slower shutter speeds.

This is a straightforward, spec-honest wide-angle prime built for shooters who prefer the hands-on control of manual focus rangefinder photography.
