Chinon 135mm f/1.8 Auto

This lens has a wide aperture of f/1.8, which means it can capture more light and create a shallow depth of field, resulting in a blurred background and sharp subject. It is a great lens for portrait photography and low light situations. The lens has several lens elements and a lens coating to reduce flare and improve image quality. The build quality of the lens is good, and it is durable. It does not have autofocus, so the photographer needs to manually focus the lens. The lens was manufactured in the past, and it may be difficult to find a new one. There are alternatives to this lens, such as other 135mm lenses from different manufacturers. The resolution of the lens is good, and it can produce sharp images. The bokeh, or the quality of the out-of-focus areas, is also good. Overall, the Chinon 135mm f/1.8 Auto lens is a good option for photographers who want a fast prime lens with a wide aperture and manual focus.
