Canon has been working on their own focal length reducers. Lens adapters commonly sold under “speedbooster” or similar names, these adapters translate a larger projection circle, like that from a full frame lens, to the smaller sizes needed by APS-C and smaller sensors.
Lens adapters to put Canon EF mount lenses onto M mount bodies are nothing new. Canon’s had one for a while now. But when it comes to speedbooster style adapters, one company’s pretty much had the market sewn up, and that’s Metabones. But Metabones only produces such adapters for Sony, Micro Four Thirds and Fuji crop cameras. At least for now.
A new Japanese patent (2018185393) suggests that Canon will be working on their own, now, though, breathing some new life to their EOS M mount line of cameras – as well as their EF mount lenses as they make the push towards full frame mirrorless.
Canon has stated that their new full-frame mirrorless line will sit alongside their existing systems in their product lineup. That an APS-C format mirrorless in the EOS R is essentially not possible, and that EOS M will continue to live on and see development.
True to their word, a new patent has just surfaced for a potential 10mm f/2.8 Fisheye lens design. The short backfocus distance suggests that it is for a mirrorless camera with an APS-C projection size. Given that it’s APS-C, it won’t be for the EOS R, but for the EOS M line.
It looks like Panasonic isn’t the only company not giving up on their previous range of mirrorless cameras despite bringing a new one out. Despite the recent EOS R announcement, Canon Rumors reports that Canon is planning to release two new EOS M mirrorless cameras next year. And, no, I doubt any of them will be full frame.
The original Canon EOS M mirrorless camera from 2013, the camera summarily dismissed by pretty much everybody as a pretty terrible camera, can now shoot 2.5K RAW video. Sort of. It’s all thanks to a new sd_uhs module in Magic Lantern which overclocks the write speed of the SD card.
It’s definitely a case of “Don’t try this at home!” unless you know what you’re doing or are willing to accept the risks, though. There have been reports of SD cards dying, and Magic Lantern currently doesn’t recommend its use. But it’s still available, and if it doesn’t kill anything lets you shoot 12Bit lossless 2.35:1 raw video.
