Lens detailRF and RF-S lenses directly; EF/EF-S using EF-EOS R adapters; EF-M incompatible; RF-S/EF-S use approximately 1.6× cropZEISS Sonnar T* fixed 35 mm f/2 lens; eight elements in seven groups with three aspherical elements, nine aperture blades and 49 mm filter thread. Macro mode focuses from 20 cm measured from the sensor plane, or 14 cm from the lens front, with 0.26× maximum magnification. Step Crop Shooting selects 50 mm or 70 mm equivalent crops at approximately 29 MP or 15 MP; these are digital crops, not optical zoom.
AutofocusDual Pixel CMOS AF II; up to 6097 still or 4641 movie selectable AF positions; people, animal and vehicle recognition plus registered-person priority; available AF area depends on lensFast Hybrid AF; up to 693 phase-detection points covering approximately 78% of the image for stills. Human, animal, bird, insect, car/train and aircraft recognition, including automatic subject selection, for stills and movies; maker AF-S detection range EV -4 to 20 at ISO 100.
ShutterMechanical and electronic first curtain 30–1/8000 second plus Bulb; electronic shutter 30–1/16000 second plus Bulb; available range varies with shooting modeMechanical shutter up to 1/4000 second and electronic shutter up to 1/8000 second; 30-second exposures and Bulb with the mechanical shutter. Maker flash-sync maximum 1/4000 second.
Burst detailUp to 40 fps electronic or 12 fps mechanical/electronic first curtain; electronic maker buffer approximately 330 JPEG or 150 RAW on CFexpress, 330 JPEG or 140 RAW on SD; mechanical buffer 1000+ RAW on CFexpress or 400 RAW on SD; pre-continuous capture up to 20 earlier frames; results depend on Canon test conditions, lens, battery, card and settingsUp to 5 fps Hi; maker buffer claims approximately 120 extra-fine JPEGs, 52 compressed RAW, 20 lossless-compressed RAW or 15 uncompressed RAW frames. RAW plus JPEG reduces the buffer further.
