Recent rumors suggest that Canon will unveil three new lenses at Photokina 2014. Those lenses are believed to be the following.
- EF-S 24mm f/2.8 STM
- EF 24-105mm f/3.5-5.6 IS STM
- EF 400mm f/4 DO IS II USM
The 24mm is rumored to be a pancake-sized lens that is probably along the size and performance of the EF 40mm f/2.8 STM but just an EF-S lens. The 24-105mm would be a nice lens to package as a kit with the Canon 6D or any other low-end, full frame DSLR that comes out in the future. And, the 400mm DO lens will replace the current EF 400mm f/4 DO IS USM model with improved optical performance.
