Here is another interview with Canon manager at Photokina 2018 by LensVid. They talked a lot about the new Canon EOS R (B&H Photo Video/Amazon/Adorama/Focus Camera/WEX/ParkCamera) and RF lenses. The interesting part is that Canon manager said that they will be focus on RF lenses, so there will no new EF lenses to be released in 2019 (Which means EF 24-70mm f/2.8L IS will coming in 2020), and Canon promised to release the “holy trinity” of RF mount lenses in 2019 (24-70mm, 70-200mm, 16-35mm, likely be f/2.8). Canon also said EOS R is not targeted for pro shooters, a high-end level EOS R Pro mirrorless camera will have a dual card slot, IBIS, fast shooting speed, 4K Video 10bit 4:2:2 internally and more.
dpreview has another interview with Canon managers about the new Canon EOS R and RF lens full frame mirrorless system. According to Canon managers, Canon gave them a greater freedom for new EOS R and RF system, and a chance to improve and innovate for the upcoming Canon EOS R and RF lenses:
The Canon RF 28-70mm f/2L USM Lens ( B&H Photo/Amazon/Adorama/Focus Camera) is a full stop faster than the standard 24-70 f/2.8 that many pros use, and that’s a HUGE deal. That reduces noise by a full stop in low-light situations. It blurs the background more than has ever been possible. Tony Northrup has compared it to the Canon EF 24-70mm f/2.8 L II and the Canon RF 24-105mm f/4L IS USM lenses. You can watch the full video above.
