Well this is interesting, who would of thought we would have not one but two affordable Raw cameras in 2012. Over at the Digital Bolex HQ comparisons are already being made. One of the kickstarter supporters Nikita Pavlov has already put a direct comparison chart on his blog I have pasted the same relevant stats below. The cameras are quite comparable, with a slightly bigger sensor on the Blackmagic and a wonderful looking touch screen. There are similarities between them CinemaDNG, a removable SSD and a SDI out. The Digital bolex has a SSD and SDI (in a separate unit) but they decided against a removable SSD because it’s not designed for frequent removal. The SDI is supposed to arrive on the Bolex via an add on $3000 unit, I’m not sure what effect the news of the Blackmagic Cinema Camera will have on this.
The Bolex comes with a mini HDMI port, WiFi and USB3.0 and Raw conversion software in the pipeline. The Blackmagic Cinema Camera comes with some wicked software Ultrascope and Davinchi Resolve as well as a Thunderbolt connection for live waveform monitoring with Ultrascope. As you can see the cameras are just begging for a head to head test, we just need them to be released.
The Blackmagic seems to be aimed towards Mac users and admittedly has an ace up it’s sleeve. The ability to compress the footage in camera to Apple ProRes and Avid DNxHD. This is fantastic addition and I wish the Digital Bolex could do this but I understand why it can’t at it’s current price point. On a final note Blackmagic have gone with a slightly bigger sized sensor than Super 16. So Cinema glass designed for super 16 like my Zeiss Super Speeds will not fully cover the sensor of Blackmagics Cinema Camera.
