Canon EF 20mm f/2.8 USM – Review

Canon EF 20mm | 27.02.2013 07:59 | Campaign against Carmel-Agrexco | Gender | Sheffield

The Canon EF 20mm f/2.8 USM was released back in 1992 and it’s one of the older designs in the current lens lineup. On APS-C DSLRs the field-of-view is equivalent to 32mm so it looses its ultra-wide character towards a moderate wide-angle lens here.

The optical construction is made of 11 elements in 9 groups without any special glass. The aperture mechanism features 5 blades. With a min. focus distance of 0.25m the max. object magnification is about 1:7. The lens feature a floating system for close focus correction. The EF 20mm f/2.8 USM has a size of 78x71mm and a weight of 405g so it is roughly comparable to an average standard zoom here. The filter size is 72mm. A lens hood is available as an option.
