This Leica M-18 Brightline Finder is a viewfinder for 18mm M-mount lenses. Its concave mirror design allows incoming light to illuminate the frame lines, providing wonderful viewing with a high-contrast image. It has been optimized for both M9 / M-E / M8 sized sensors, with lines for parallax compensation when shooting closer than 6.56’, as well as markings for the smaller sensor of the M8. Through the use of multi-layer coatings, Leica has made the Brightline Finder great for shooing in various conditions with optimal viewing quality. It also features a rubber eyepiece cover to aid shooters with glasses. Its classic design and solid brass construction make it just as pleasing to look at as look through.
