The Helios 135mm f2.8 is a telephoto lens that has a nice sharp vintage look which adds a medium amount of tension. It can film medium-close up shots from a pretty far distance.
This lens is natively an M42 mount, but has been adapted to EF. The lens is known for having swirly bokeh and rippling flares. This lens was made in Japan, but originally, Helios lenses began in Russia.
This lens covers Full Frame, Super 35mm and m4/3 digital sensors.
