Elgeet 13mm f/1.5 Elgeet Lens for C-Mount

Elgeet 13mm f/1.5: a fast wide-angle C-mount prime

The Elgeet 13mm f/1.5 is a fixed focal length C-mount lens built around a fast maximum aperture of f/1.5. That speed matters on a mount format where fast glass at wide focal lengths isn't common. A 13mm focal length paired with a f/1.5 aperture gives you a lens that gathers light aggressively while holding a wide field of view, useful when working with small-format C-mount sensors where focal lengths behave very differently than on full-frame equivalents.

On Micro Four Thirds bodies adapted to C-mount, the crop factor stretches that 13mm out to a longer effective focal length, pulling the field of view in tighter than the native 13mm number suggests. That makes this lens flexible across sensor formats than locked to a single angle of view.

C-mount primes like this one were built for compact cine and industrial camera bodies, and the mechanical simplicity that comes with a single fixed focal length shows in the way it handles: no zoom mechanism, no unnecessary glass elements, just a wide-angle optic tuned for speed. For anyone adapting vintage C-mount glass to modern mirrorless bodies, the f/1.5 aperture is the standout figure. It's a stop or more faster than most consumer wide primes from any era, and it's the reason this lens still gets picked up today.

Who It's For

Cinematographers and video shooters working with small-sensor cine cameras or C-mount-native bodies get a fast, wide 13mm option for low-light interiors and available-light documentary work where f/1.5 keeps shutter speeds and gain usable. Micro Four Thirds shooters adapting vintage glass will find the crop factor turns this into a longer-than-native effective focal length, making it suited to tighter framing than the 13mm number implies. Collectors and users of industrial or surveillance C-mount cameras benefit from the compact, fixed-focal-length design built specifically for that mount. Anyone experimenting with lens character on modern mirrorless bodies through an adapter gets a wide-aperture optic that's genuinely uncommon at this focal length.

FAQ

What's the effective focal length on Micro Four Thirds adapted to C-mount?

The 2x crop factor on MFT stretches the 13mm to approximately 26mm equivalent, pulling the field of view tighter than the native focal length suggests. That makes the lens narrower in angle of view than a 13mm on full-frame.

Why does an f/1.5 aperture matter on a C-mount prime?

Fast glass at wide focal lengths isn't common on the C-mount format. An f/1.5 maximum aperture is a stop or more faster than most consumer wide primes from any era, giving you significant light-gathering ability in a compact fixed focal length design.

Is this lens designed for modern cameras?

No-the Elgeet 13mm f/1.5 was built for vintage compact cine and industrial camera bodies. It's adapted to modern mirrorless systems via C-mount adapters, which is how it finds use today.

What's the advantage of a fixed focal length C-mount prime?

No zoom mechanism and no unnecessary glass elements means optical simplicity tuned for speed. That mechanical straightforwardness is typical of C-mount primes built for industrial and cine work.

Can I use this on different sensor formats?

Yes. The same 13mm lens behaves differently depending on your sensor's crop factor. On MFT it's a 26mm equivalent; on other adapted formats the effective focal length shifts accordingly while the optical design stays the same.

What mount does this lens use?

C-Mount, a legacy cine and industrial standard. You'll need a C-mount-to-your-camera adapter to use it on modern mirrorless bodies.
