Leica Green Filter E49 Black: Vibrant Contrasts for Monochrome Cameras. The Leica Green Filter E49 black is a high-quality color filter, specially developed for black and white photography with Leica Monochrom cameras to optimize contrast and enhance natural tones. With a diameter of 49 mm, it is made of multi-coated optical glass that reduces reflections and preserves image quality. The green tint brightens greens, darkens reds, and emphasizes details in vegetation or skin tones – ideal for landscapes, portraits, or artistic shots. The black aluminum frame combines robustness with iconic Leica design. Compatibility: Perfect for Leica M Monochrom models such as the M10 Monochrom or M Monochrom Typ 246, as well as M lenses with a 49 mm filter thread, e.g., the Summicron-M 35mm f/2 ASPH or APO-Summicron-M 50mm f/2 ASPH. Equally compatible with the Leica Q series (Q, Q-P, Q2, Q2 Monochrom, Q3) for creative black and white effects. This filter is an indispensable tool for Leica photographers who want to refine their black and white photography with monochrome cameras and offers inspiring possibilities for M and Q systems.
