Russian certification authority Novocert has registration document for two Canon lenses: the already rumored EF 35mm f/1.4L Mark II, and a lens for the EOS M system, the EF-M 15-45mm f/3.5-6.3 IS STM. The latter never surfaced in a rumor.
The EF-M 15-45mm f/3.5-6.3 IS STM could be Canon’s next kit lens for the EOS M series cameras. Back in May we had a rumor pointing in this direction, though an 18-55mm IS STM Mark II lens was then mentioned as the new kit lens. However, I would be surprised if the EF-M 15-45mm is not going to be the next EOS M kit lens. Though, an f/6.3 at the telephoto end is a bit disappointing.
The announcement of both lenses should be matter of weeks. In the past, states Digicame Info, the event of a registration at a certification authority usually anticipated the announcement for a few weeks. So, most likely these are the two lenses that will be announced August 14, 2015.
