The folks at Blackmagic design are at it again when it comes to destroying spec sheets compared to price. The BMPCC 4k was already one of the best-reviewed and popular choice among budget filmmakers that needed excellent quality and dynamic range. At only $1,295 that camera was a smash hit but had only a four thirds (4/3) sensor which was not ideal in size and required speed booster adapters to get the needed depth of field to simulate an S35 image.
Now the BMPCC 6k ($2,495.00) with EF Canon mount comes in with a full APS-C sensor with dual ISO characteristics like before but with the added imager size and full electronic lens support for EF glass. It would have been in our view ideal to use an electronic mount with shorter flange like the Sony Alpha or the new Canon RF mount so you could adapt even more lens combinations but they are catering to a large installed base of glass owners.
