Canon today introduces its first professional camera in the EOS Cinema series with RF-
bayonet. As the name number suggests, the EOS C70 is rather placed in the lower segment of the Canon Cinema models. The C70 is also rather modest in size and looks like a DSLM that is a bit too thick.
The first thing you notice when differentiating it from the DSLM are the additional ventilation slots and the missing viewfinder. But the biggest difference becomes visible only at second glance. The camera has an integrated ND filter with up to 10 steps!
Despite RF-Mount no full format sensor was installed. Instead there is a S35 sensor of the C300 MkIII with dual gain output inside. Thanks to the latter, Canon promises a similar dynamic range as the C300 Mk3 even with 16+ f-stops, which is approximately on the level of current full format DSLMs.
A movable mounting of the sensor has also been omitted, although the full format image circle naturally seems almost predestined for this. Instead, there is a digital image stabilizer, which, however, cannot use any excess pixels due to the native C4K resolution of the sensor.
Up to C4K is recorded in several recording formats on SD cards (2 slots). Clog 2/3 can record up to 120 fps in 4K 4:2:2 10 Bit with Dual Pixel CMOS AF and sound recording. As codecs XF-AVC (All-I or Long GOP) or MP4 in HEVC (H.265) or H.264 are available. RAW recording is not supported internally or externally.
Nevertheless, the "compact outer skin" contains almost all the typical control elements of EOS C cameras, which is why previous C-filmers should quickly find their way around. There are 13 configurable, numbered buttons on the camera body and professional input/output functions.
/outputs including time code and large HDMI jack. The two mini-XLR-sockets, which are already known from the Blackmagic Pocket, are the most prominent connections.
Even the typical XLR audio terminal with manual control options can be placed under the display.
The display itself can be rotated and swivelled sideways, even up to self viewing. The camera can also be set up for vertical video. Among other things, with the help of an additional tripod thread on the side and an optional menu view in upright format.
The BP-A30 battery is included in the scope of delivery, which promises working hours of over 3 hours with the C70.
Canon announces a small additional bang with the new bayonet adapter EF-EOS R 0.71x. This is a Focal Reducer alá Speedbooster. This adapter converts from EF to RF mount and enlarges the image circle from S35 to full format.
As usual, you even gain one f-stop of luminous intensity. And since the adapter is from Canon itself, vignetting correction as well as chromatic aberration correction are supported by the adapted EF optics in addition to autofocus. Even the complete exchange of the EF lens metadata should work. .
The EOS C70 will be available from November 2020 at a price of EUR 5,219 including VAT. The new EF-EOS R 0.71x bayonet adapter is expected to be available from December 2020 at a price of 579 Euro incl. VAT.
