Product description
Discuss in the Canon SLR Lens Talk forum

The Canon EF 20mm F2.8 USM was one of the first wide angle prime lenses created for Canon's EOS system back in the early 90s. Despite its age, it remains a popular lens among full-frame Canon shooters for its compact and lightweight build, and relatively low cost. Optically, there are better primes available in Canon's current lineup, but fitting in the gap between 14mm and 24m, there is no direct sucessor to this venerable lens at the time of writing.
