Design and Features
Exceptionally fast standard prime lens and together with Canon EF 85mm F/1.2L II USM (2006) one of the fastest lenses in Canon’s current lineup. The lens was designed for superior bokeh and offers extremely fine control over depth of field. At the present time it is a very popular lens for portrait and event photography in available and low-light conditions.
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 of moderate weight, dust-proof and water-resistant, made of high-quality plastic. The lens mount is metallic. The focusing ring is ribbed and rubberized, well damped, moves very smoothly, has reasonable width and angle of rotation of 140 degrees for comfortable focusing.
The lens uses front element linear extension method for focusing however the front element does not extend beyond the lens barrel during focusing.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
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 lens is equipped with ultrasonic motor, the autofocus is virtually silent and moderately fast.
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.
The sharpness at the center of the frame is good at F/1.2-1.8, very good at F/2.8 and excellent from F/4. The edges are mediocre at F/1.2-2.8 but very good from F/4. 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. The lens suffers from focus shift when stopped down though.
