It is a balanced goal because it is relatively small and light. The focus ring rotates around 110 ° being soft and with little resistance.
It has moderate contrast loss and some backlight phantom effect. In f / 1.4 the vignetting is very remarkable, in f / 2 it is less noticeable and since f / 2.8 there is no vignetting. It does not stand out for its bokeh. In f / 1.4 it is very useful for portraits and from f / 2.8 it will give very good results for almost any situation.
The lens is designed for Canon 35mm film SLR cameras and is not compatible with Canon EOS digital SLR cameras.
