EF 50 f/1.8 IS USM
We’re told that a new EF 50mm f/1.8 IS USM is ready for release, but may not happen until Q1 of 2014.
The lens would be in line with the new 24,28 & 35mm IS lenses. Pricing would be more than the current EF 50 f/1.4 USM it would be replacing. However, Canon has noticed that the pricing on the 3 mentioned lenses at launch was too high and lead to poor initial sales numbers. Since the lenses have been price dropped, they are selling better.
