看佳能规划的RF1200mmF8.0和佳能折反射镜的历史！
This is the Canon RF lens roadmap for the next couple of years. I will be updating this list as new information comes in.
Canon RF Tilt-Shift Lenses:
Canon TS-R 14mm f/4L
Canon TS-R 24mm f/3.5L
These lenses will be the first tilt-shift lenses to have autofocus.
Canon RF Zoom Lenses:
Canon RF 10-24mm f/4L USM
Canon RF 14-35mm f/4L IS USM
Canon RF 18-45mm f/4-5.6 IS STM
Canon RF 70-200mm f/4L IS USM (Announced November 4, 2020)
Canon RF 100-400mm f/5.6-7.1 IS USM
Canon RF Prime Lenses:
Canon RF 35mm f/1.2L USM
Canon RF 50mm f/1.8 STM (Announced November 4, 2020)
Canon RF 135mm f/1.4L USM
Canon RF Macro Lenses:
Canon RF 24mm f/1.8 IS STM Macro
Canon RF 100mm f/2.8L Macro IS USM (Announced April 14, 2021)
Canon RF Super Telephoto Lenses:
Canon RF 400mm f/2.8L IS USM (Announced April 14, 2021)
Canon RF 500mm f/4L IS USM
Canon RF 600mm f/4L IS USM (Announced April 14, 2021)
Canon RF 800mm f/5.6L IS USM
Canon RF 1200mm f/8L IS USM
This may not be a complete list of upcoming lenses for the Canon RF mount for 2020 and beyond. While the original source told me that these lenses were initially scheduled to arrive by the end of 2021, there may be delays for obvious reasons. That said, I think Canon will do their best to make a huge splash ahead of the Tokyo Olympic Games next year.
佳能折返镜头的历史
关于佳能和折返镜头的谈论很多可能是在于RF的新透镜设计专利浮出水面。传闻已久佳能将为EOS R系统带来一个RF1200毫米f/8镜头，它实际上可能是一个折返镜头。
佳能确实有折返镜头的历史，包括庞然大物的佳能5200毫米f/14折返镜头以及800毫米f/3.8折返镜头和2000毫米f/11折返镜头。
这些折返镜头是在20世纪60年代中期开发的，在二手市场上仍然可以卖到很高的价格。几年前，5200毫米f/14折返镜头在易趣上售价约为5万美元。
