Canon EOS-M EF-M mirrorless system
introduction
-
In July 2012, Canon finally announced a mirrorless compact system camera - the EOS-M - an entry level camera and 2 EF-M mount lenses designed for it - 22mm F2 STM and EF-M 18-55mm F3.5-5.6 STM IS
hardly inspiring, and despite early thoughts they they would choose a 2x crop sensor like
Micro Four Thirds system so they could get the best of all worlds - small lenses and great image quality, they have succumbed to Canon conservatism and chosen yet another APS-C 1.6x crop sensor camera system
the lenses use their new STM AF technology designed for smooth, quiet CD-AF performance
now that Canon has introduced a largely incompatible full frame mirrorless system, the
Canon R full frame mirrorless camera system, I am not sure where that leaves the EOS-M “system” which will not be able to use the new R lenses, nor will the R system use the EF-M lenses, so will Canon really commit to rapidly expanding the range of quality native lenses for both systems?
lens mount
electronic bayonet mount, with 9 contacts between the lens and camera.
departing from Canon's usual mounting mechanisms, the white dot for aligning the lens is at the 11 0'clock position on the mount.
47mm in diameter (almost 1mm wider than the Sony NEX but 7mm smaller than the Canon RF full frame mount)
flange distance of 18mm from the bayonet to the sensor, same as the Sony NEX and just a tad shorter than the 20mm Micro Four Thirds flange distance
camera bodies
Canon EOS M50 II
announced Oct 2020
24mp
4K 24p
$US599
Canon EOS M6 II
announced Aug 2019
32mp, 14fps, Dual Pixel AF, Eye tracking AF, optional add-on EVF
4K 30/25p; 1080 120/60/30p
408g $US849
Canon EOS M50
Feb 2018
24mp; Dual Pixel AF 99pts (143pts with compatible lenses); Digic 8; 7.4fps C-AF; 10fps no AF; 2.36m dot EVF; supports C-RAW for 40% smaller files;
4K 24p video is 1.7x crop giving a total 2.7x crop factor (and even greater if using digital IS) and no DualPixel AF only CDAF and significant rolling shutter issues
1080 30/60p with DualPixel AF
Eye AF only in AF-S mode (not in video or Servo mode)
only one control dial, no weathersealing, no sensor based IS, no USB charging
Digic 8 processor
-
Canon EOS M6
Canon EOS M5
announced sept 2016
APS-C, 24mp, 1080HD, 45pt dual pixel AF, 1/4000th sec shutter, 7fps
-
Canon EOS M3
announced Feb 2015 as a token gesture given they still have only four EF-M lenses in its range, and only one would be interesting to an enthusiast - the EF-M 22mm f/2 STM but even with the STM lenses, AF speed cannot compete with other mirrorless systems such as Micro Four Thirds, although AF works acceptably well with the works well with the 18-55mm kit lens
2)
24mp APS-C sensor
49pt AF and new Hybrid CMOS AF III
tilting LCD, optional EVF
MF peaking
video almost as good as the 2011 Panasonic GH2 but with much more moire and aliasing artefacts
no where near as good as the Panasonic LX100
it is so far away from competing with the features or lens line up of
Micro Four Thirds system - it seems it won't even be marketed in USA - why bother when there are far better options for users in the mirrorless world
will AF a Canon EF lens better than a Metabones adapter on a Sony but that is not saying much!

Canon EOS M
18mp sensor with Hybrid CMOS AF and ISO 100-12,800 (25,600 with boost)
31pt AF
phase detect AF component only works with STM lenses
fixed 1,040K LCD touch screen
no built-in flash (standard EOS hotshoe) and no EVF and no EVF port
flash x-sync speed 1/200th sec
shutter 60sec - 1/4000th sec
4.3fps burst, 3fps with AF tracking
1080p HD video at 24, 25,30fps in MPEG-4 H.264 format with stereo mics (essentially the same HD video as in the Canon 650D)
298g 109x66x32mm - just a touch bigger than a Panasonic GF-5
bundled AAA battery Speedlite 90EX flash
optional GPE2 GPS recorder
optional EF-M to EF lens adapter (RRP $US200) although given this is a very basic camera and not ergonomically designed for such lenses, users would be far better off with a dSLR, after all it isn't adding higher grade video, nor built-in IS, nor ergonomics or AF speed to entice users into using it with EF lenses.
for a camera which forces users to compose through the LCD screen at arms length, the absence of built-in image stabilisation is a real pity
initial previews suggest AF speed with dedicated new lens is much slower than Olympus and Panasonic
lack of physical controls will not suit the street photographer
RRP $US800 with pancake lens price at announcement is much higher than competition for few benefits and lots of negatives
EF-M lenses
Canon EF-M 22mm F2 STM
equivalent to 35mm lens field of view on a 35mm full frame camera
compact pancake lens which should make a reasonable street photography lens, pity it is not image stabilised to allow for more versatility at night without a tripod or flash
6 elements / 7 groups
close focus 0.15m
43mm filter thread
60.9×23.7mm
105g
Canon EF-M 15-45mm F3.5-6.3 IS STM
Canon EF-M 18-55mm F3.5-5.6 STM IS
equates to 29mm - 88mm field of view
13 elements / 11 groups
close focus 0.25m
filter thread 52mm
“4 stop” IS for stills but can add more IS functionality during movies by activating dynamic IS mode
60.9x61mm but lens extends on zooming
120g
should be a reasonable travel lens and the kit ends up being half the weight of a Canon dSLR with kit lens
similar sized lens to the Olympus mZD 14-42mm kit lenses but twice as long as the ultra compact Panasonic PZ kit lens.
RRP $US300
Canon EF-M 11-22mm f/4-5.6 IS STM
announced June 2013
equates to 18-36mm fov
3 stops IS
0.15m minimum focusing distance
much smaller than Canon's EF-S 10-22mm f/3.5-4.5 USM but then it is not as bright
-
weird atypical 55mm filter thread size!
220g
61mm diameter x 58mm length (retracted but in use, 74mm when zoomed to 11mm)
very similar in size and appearance to the EF-M 18-55mm lens
