Design and Features
Suited for indoor or other low-light conditions where F/2.8 wide-angle lenses may impose restrictions on the shutter speed. Aside from the faster speed the lens has the following advantages compared to the Canon EF 28mm F/2.8 (1987):
- USM with FTM (AFD without FTM in case of 28/2.8),
- ASPH element for better correction of aberrations,
- smaller closest focusing distance (0.25m compared to 0.3m).
The lens barrel is compact, of moderate weight, made of plastic. The lens mount is metallic.
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 58 mm which are easy to find. They are also inexpensive.
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 very fast.
Aspherical elements (ASPH, XA, XGM) minimize spherical aberration, astigmatism, coma and ensure excellent sharpness and contrast even at maximum aperture.
The sharpness is very good at the center of the frame already wide open and becomes excellent at subsequent apertures. The edges are mediocre wide open, good at F/2.8 and very good at subsequent apertures. The corners are soft at F/1.8-2.8, good at F/4 and very good at subsequent apertures.
