I'm selling a Japanese-made Avanar 135mm f/2.8 prime lens with Dyna Coated multi-layer coating. This is an excellent manual lens for portraits and creative photography. The fast f/2.8 aperture combined with the 135mm focal length allows for beautiful background blur (bokeh) and easily separates the subject from the background. The lens has a built-in retractable metal hood that provides excellent protection from backlight and side light. Thanks to the popular vintage M42 mount, this lens can be easily mounted on virtually any modern digital camera (DSLR or mirrorless) using an inexpensive adapter.
