Wow! What an announcement! This new camera is very close to the old Scarlet 3k for $3000 that was promised long ago. Instead this is a $3000 camera with a built-in $1000 RAW recorder, $1000 software, $750 Canon EF mount and a $250 camera?
Of course this has opened up more questions about how the camera operates, and the lens choices possible. The sensor itself is very interesting. 13 stops DR, if true, is much higher than competing DSLRs. Doing a little searching around, there was a sensor announced in 2009 – A sCMOS sensor with very high DR with an active pixel area of 16.64×14.04mm, exactly the same as this new blackmagic camera. Another camera with an sCMOS sensor is the pco.edge, an industrial camera, but maybe a good camera to look at the datasheet for to see lower resolution high speed options that are available with this sensor. I’m not saying this sensor is in the new blackmagic camera, but it looks very similar.
On to camera mounts: The ideal mount for this camera would be a 4/3 mount that is adaptable to PL, B4, OCT-18/19, EF, Nikon F, PK, OM, and I’m sure I’m forgetting a few. From the spec sheet and website it says that is supports both EF and ZF, but only pictures of EF lenses are shown on the camera. Hopefully this will be cleared up soon. With a 4/3 mount you could use the excellent lenses designed for this sensor size already from Panasonic, Olympus and Voightlander. For now, the Ideal zoom is the Tokina 11-16 – hopefully electronic in both Canon EF and Nikon G mounts.
