Special thanks to Andreas Thaler who has provided the lens for testing purposes!
Introduction
Released back in 1995 the Canon EF 28mm f/1.8 USM is one of the few relatively new
fix-focal in the lower focal length range that we've seen in the last years.
Regarding its release date it is obviously a full frame lens. On APS-C DSLRs
it has a field-of-view equivalent
to a classic 45mm lens so it can be considered as a standard lens here. As such
it competes with the Sigma AF 30mm f/1.4 EX HSM DC
and to a lesser degree with its in-house mate, the EF 35mm f/2.
The optical construction is made of 10 elements in 9 groups with one aspherical element.
Its minimum focus distance is 0.25m resulting in a max. object magnification
of 1:5.5. The aperture mechanism has 7 aperture blades. The filter size is 58mm.
It has a size of 74x56mm and despite its large aperture the weight is relatively moderate
at only 310g. A petal-type hood is optional.
The lens is quite a beauty with a very solid construction thanks to very good quality plastics.
The very broad, rubberized focus ring has a smooth action. The front element does not rotate
so using a polarizer is no problem. The focusing speed is pretty fast
and thanks to USM the AF noise level is near silent. Typical for ring-type USM drives
full-time manual focusing is possible.
