The Canon EF 28 mm f/ 2.8 is an exceptionally compact fast wide-angle lens for Canon EOS film and digital cameras.
The lens is inexpensive, but rather good in terms of its characteristics.
The optical scheme includes an aspherical element, which makes it possible to reduce the lens dimensions and greatly minimize spherical aberration.
Thanks to a small number of optical elements in the lens construction, transparency increases, and the risk of spurious flare, which affects contrast, is minimized. Besides, a small number of elements make the lens less expensive and thus more affordable for users. However, it is well known that the best of Carl Zeiss and Leica lenses rarely utilize more than 5 or 6 elements in their schemes.
With a wide angle and a 2.8 lens speed the Canon 28 mm f/2.8 shows good results in poor lighting conditions without a tripod or a flash.
It is rather sharp at f/2.8. And it is very sharp from f/4 onwards.
It has a 5-blade aperture. Despite the fact, out-of-focus blurring (bokeh) is rather good. Point light sources are blurred into almost a full disc, and in general, pentagons, characteristic of such lenses, are not clearly pronounced.
A built-in focusing motor is rather noisy. Focusing in poor lighting conditions is often difficult.
The lens is not well resistant to back and side light. A hood is strongly recommended.
The Canon EF 28 mm f/2.8 is useful for landscape, architecture, interior and genre photography. It can be used for full-length portraits. It is ideally fit for video shooting on modern SLR cameras. In general, a rule of thumb states that 28 mm is one of the most popular focal lengths. It is very good as a kit lens for APS-C (crop factor) cameras. Equivalent focal length in this case is 45 mm.
Compatible hood: EW-65II
