Digital Camera World Verdict

The Funleader 18mm F8.0 for Leica M mount is slim, feels rather well made and has a smart retro look without the price tag of a regular retro Leica fit lens. Unfortunately, the optical performance doesn’t live up to the smart metal exterior, with heavy vignetting and softer edge detail on the left side than on the right.

The Funleader 18mm F8.0 for Leica M is sold alongside the regular Funleader 18mm F8.0 for mirrorless cameras that we’ve already reviewed. This one, however, is made to fit cameras that use the Leica M bayonet mount. That includes old Leica film-based rangefinders and the latest digital versions.
