90mm · f/2
The Leitz Summicron 90mm f/2 (I) is a classic portrait lens with a solid build and smooth focusing. Optically, it offers pleasing sharpness wide open and excellent micro-detail, though it is softer and lower in contrast compared to modern APO versions. Its 11-blade aperture produces smooth bokeh. The lens is heavy and has a long focus throw, making precise adjustment easy but slow. It suits photographers seeking a classic rendering at an affordable price, but those wanting maximum sharpness may prefer the APO version.
