Laowa Leica M mount Ultra-wide prime
Laowa 11mm f/4.5 FF RL
Quick answer
The Laowa 11mm f/4.5 FF RL is a ultra-wide prime lens covering 11mm at f/4.5 for the Leica M mount. Its smaller maximum aperture favours daylight shooting and keeps the lens compact.

Frequently asked questions
What mount does the Laowa 11mm f/4.5 FF RL use?
It uses the Leica M mount, so it fits Leica M cameras directly and can be used on other systems through a mount adapter.
What is the focal length of the Laowa 11mm f/4.5 FF RL?
It is a fixed 11mm lens with a maximum aperture of f/4.5. That makes it a ultra-wide lens.
Is the Laowa 11mm f/4.5 FF RL a prime or a zoom lens?
It is a prime lens with a fixed 11mm focal length. Primes usually open wider than zooms; this one opens to f/4.5.
What is the Laowa 11mm f/4.5 FF RL equivalent on a crop sensor?
On APS-C (1.5x crop) it frames like 17mm on full frame, with a 95° horizontal and 105.3° diagonal field of view. On Micro Four Thirds (2x crop) it frames like 22mm on full frame, with a 78.6° horizontal and 89° diagonal field of view. These figures are calculated from the focal length and crop factor.
Which cameras does the Laowa 11mm f/4.5 FF RL fit?
Any Leica M-mount camera, including Leica M (Typ 240), Leica M-D (Typ 262), Leica M10-D, Leica M10-P, and Leica M10-R and 15 more.
