The Canon 85mm F1.8 LTM is arguably the best Canon 85mm RF lens made. It is relatively hard to find and has very high reputation as a portrait lens without the softness associated with most vintage lenses. It has similar resemblance to the older Canon 100mm F2 LTM lens but with improved ergonomics and optical performance.
The Canon 85mm F1.8 is a solid and compact lens for its focal length. It’s compact dimensions and solid build quality is perfect balance on Leica M Rangefinders. The lens is all metal construction with design consisting of focusing and aperture ring turning simultaneously.

The Lens offers a relatively fast maximum aperture at F1.8. When shot wide open, it produces pleasant bokeh and smooth out of focus area. The image rendering is classic with natural and vibrant colours.

The focusing throw on this lens is very long but very smooth at the same time. When adjusting for aperture, since the lens has no dual helicoil mount and the aperture ring turns with focusing throw. This can be confusing during practical use as both aperture and focus turn at the same time.
