Chinon 135mm f/2.8

The Chinon 135mm f/2.8 camera glass has a high-quality build and is suitable for manual focus photography. It has a wide aperture of f/2.8, which allows for good bokeh, or the pleasing blur in the background of photos. This photographic lens has six lens elements that are coated to reduce glare and improve image quality. The manufacturing of this glass took place in the past, so it is no longer produced, but it is still available in the market as a used option. The resolution of this lens is good, producing sharp images. It is a good alternative for those who are looking for an affordable prime lens.

Optical design

Has 6 aperture blades, this number of blades are commonly used. Having rounded blades provides out of focus circle shape closer to a circle. Bright lens thanks to the high aperture value

Physical characteristics

Weights 400 grams so plan ahead, carry only if really necessary. 52 mm lens filter diameter, you are one step from the next standard filter size, buy step-up ring and bigger filter but you can chose from plenty options. 87 mm long, requires consideration if you want to carry in the camera bag.
