Design and Features
Exceptionally fast medium telephoto prime lens. It was designed for superior bokeh and offers extremely fine control over depth of field. The autofocus speed was improved compared to the first model (1989).
The lens is a part of Canon’s series of Luxury lenses notable for their excellent build quality and robust design. The lens barrel is heavy, made of metal. The lens mount is metallic.
The focusing ring is not physically coupled with the focusing mechanism and works electronically (focus-by-wire) - turning of the ring actuates an electric motor that moves the focusing group of the lens to the proper position to achieve sharp focus.
The camera must be powered on for manual focus to work. The focusing ring is ribbed and rubberized, has reasonable width and angle of rotation of 250 degrees for comfortable focusing. It moves very smoothly but too freely and has some play which makes it harder to fine tune the focus compared to conventional mechanical rings.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
Full-Time Electronic Manual Focusing is performed in the following way - half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the manual focusing ring.
The lens uses front filters with standard size of 72 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
The lens is equipped with ultrasonic motor, the autofocus is virtually silent and reasonably fast compared to the predecessor.
The lens is based on almost symmetric variant of double Gauss design which is one of the most developed lens designs in the world frequently used for large aperture standard prime lenses and large aperture moderate wide-angle prime lenses. It provides excellent compensation of aberrations, except for the oblique spherical aberration which lowers peripheral contrast.
Aspherical elements (ASPH, XA, XGM) minimize spherical aberration, astigmatism, coma and ensure excellent sharpness and contrast even at maximum aperture.
Extra refractive index elements (XR, UXR, HID, HR, HRI etc) minimize aberrations and allow the development of smaller and lighter lenses.
The lens incorporates a floating system that provides correction of aberrations and ensures constantly high image quality at the entire range of focusing distances from infinity down to the closest focusing distance. Learn more
The sharpness is very good at the center of the frame already wide open and excellent at subsequent apertures. The edges of the frame are good wide open and very good at subsequent apertures. The image contrast is high and the background blur is very smooth and pleasant at large apertures. The subjects look almost three dimensional at large apertures due to high micro contrast and smooth transition between in-focus and out-of-focus areas of the image.
