Now it&s a fact: Canon today introduced two mirrorless APS-C cameras based on the RF mount. While APS-C has been rather a niche existence among professional photographers in recent years and was hardly to be found in professional housings for mirrorless cameras, many filmmakers still haven&t warmed up to the "large format" and still see the S35/APS-C format as THE sensor size for cinematic work. And it is this aspect that makes the new EOS R7 and R10 particularly interesting for scenic applications.
The less expensive and somewhat smaller EOS R10 (from July 2022 for 979 euros, 429 g) has a 24.2-megapixel APS-C sensor, while the EOS R7 (from June 2022 for 1499 euros, 612 g) comes with a 32.5-megapixel APS-C sensor. Both bodies, by the way, come with an EF/RF mount adapter, which makes the switch from the EF mount particularly palatable. The R7 also features a moveable sensor and is weather sealed. The EOS R7 can combine IBIS with optical as well as Movie Digital IS for stabilization. The EOS R10 uses data from lenses with optical IS to support the effect of Movie Digital IS...
Both cameras can record 4K from 24p up to 60p in YCbCr 4:2:2 10-bit, with only the R7 also enabling Canon Log 3 recording with Cinema Gamut in the process. Both cameras are capable of downsampling the entire sensor area, although the R10 can only use 64% of the sensor area in 1:1 readout at 4K60p. Both cameras also allow 120p recording in HD.
The EOS R7 is said to be able to record continuously for up to six hours, while the EOS R10 can record for up to two hours in 4K 60p. On the heat limits, Canon gives the following specifications:
- High frame rate videos (Full HD 120/100 fps): 90 minutes.
- 4K 30p HQ: approx. 60 min. at +23 °C output temperature.
- 4K 60p Crop: approx. 60 min. at +23 °C output temperature.
- If the internal camera temperature is too high, the maximum recording time is reduced.
Recording is done on SD / SDHC / SDXC (UHS-II), with the R10 having one slot and the R7 two. YUV output with up to 10 Bit 4:2:2 via HDMI is also available - but no RAW output for the Atomos recorders.
Guard for filmmakers, the Canon EOS R7 in particular is thus perhaps a real announcement (as long as the 4K downsampling has been implemented cleanly). An S35 camera with a moving sensor, DualPixel AF and 10-bit 4:2:2 Clog 3 double-slot recording leaves little to be desired for many applications. And that for 1500 Euros incl. EF mount compatibility.
