The second half of 2018 will be a busy year for Canon's announcements. In addition to EOS-M50 announced in February , the company is expected to release a new EF-M 32mm f/1.4 STM prime lens for the EOS-M mirrorless camera. Slightly shorter than a 50mm full frame equivalent.
More interestingly is the replacement to the venerable EF 70-200mm f/4L IS lens with the Series II model. This is a stable glass for many photographers, from wedding to wildlife. Too early to know what the new lens will come with but both pieces of glass are expected around the time of the Photokina Show in Germany in September. Keep checking back for the latest information.
