Introduction
- the 1st camera released by the new OM System owner who bought the Olympus camera division and decided to name their 1st camera the OM-1 to celebrate the 50th anniversary of the original film SLR OM-1 and to outline the break in company ownership hence it is not named the OM-D E-M1 Mark IV even though it is an evolvd version of the OM-D E-M1 Mark III and includes most of the features of the Olympus OMD E-M1X pro sports camera but with further improvements.
- announced Feb 2022
- Improvements over the Olympus OM-D E-M1 Mark III:
- new stacked 20mp sensor
- up to 2 stops noise improvement, as well as an extra 1 stop of dynamic range (perhaps tests don't really confirm this but at least the image quality is not far off full frame for ISO 6400 and below)
- completely new, and first to market ‘Quad Pixel AF’ system, with 1053 cross-type AF points (10x more than the E-M1III) and now covering the entire sensor and AF is sensitive down to -5.5 EV
- up to 50fps electronic burst with Continuous AF
- sensor read out ~1/125th sec thus 1 step better rolling compensation, as well as improved panning compensation
- now it's possible to shoot 10-bit video (at 4:2:2 externally), 4K 60p, and 1080p 240p and there's no 30-minute record limit and no 4Gb file size limit!
- AI subject tracking now supports planes, trains, motor vehicles, birds, and animals such as cats and dogs, with both subject and face/eye detection, and this is said to be 3x faster than the E-M1X. Tests show that AF for birds is now almost as good as a Sony a1 or Canon R6.
- many other improvements see below under specs
Specs
- essentially an E-M1III and EM-1X (without the form factor) but with many updates:
- new 20mp IMX472 stacked backside-illuminated CMOS sensor from Sony and has a sensor readout of 1/125th sec and 1053 quad-pixel PDAF points (previous cameras had 121)
- 3x more powerful processor TruePic X Dual Quad Core Processor
- 2 stop improvement low light with “Quad Bayer Structure”
- Auto ISO can go up to 25,600, whereas Auto ISO stopped at 6400 on prior cameras
- extend ISO to 102,400, whereas the E-M1X/E-M1 III tops out at ISO 25,600
- AF focus down to -8 EV (with an F1.2 lens)
- adds a separate AF-ON button, so the camera includes independent AE-L and AF-ON buttons
- improved AF tracking
- 2x more accurate and 3x faster AI detection AF than E-M1X and which now detects Formula cars, rally cars, motorcycles / Aircrafts, helicopters / Bullet trains, standard trains, steam locomotives / Birds / Dogs, cats
- astro tracking?
- 7EV IBIS (8EV with dual sync OIS lenses)
- 5.76Mdot EVF with zero blackout capability at up to 120fps burst
- higher res 1.62mdot LCD panel
- larger grip
- completely re-worked menu system
- mechanical shutter life is rated to 400,000 shots
- ProCapture and sequential burst increased to 120fps but limited to 92 frames (139 RAW at 10fps) but double that of previous E-M1 cameras
- 50fps burst with AF (with 6 PRO lenses otherwise max with AF is 25fps) and AE, 120fps with locked AF and AE
- faster even than the Sony A1 and Canon EOS R3 which are limited to 30fps with AF
- Buffer allows 90 frames using a ProGrade Digital UHS-II SD card with 250 MB/s write speed and then takes 25secs to clear but you can continue to shoot at 50 fps, albeit with a reduced buffer. If you shoot 90 frames and wait a few seconds, you can shoot another burst of 10 photos.
- HiRes modes 25Mp, 50Mp handheld plus 80mp tripod, these are completed twice as fast as in the EM1III
- Live ND now has a 6 stop ND mode
- 4K video to 60p 202Mbps now with either UHD or DCI ratio
- can shoot for up to 90 minutes on a single battery, before the battery is exhausted and for over 2 hours when using an external power source without overheating concerns
- can output 4K Raw video: C4K, 60p, 4:4:4, 12-bit external recording using Apple ProRes RAW with Atomos Ninja V support
- 1080p video now up to 100/120/200/240p
- can use as a very high quality webcam using Olympus’s free webcam software.
- two UHS-II SD card slots, up from a single UHS-II SD card slot and a second non-UHS-II card slot in previous cameras.
- Bluetooth 4.2 LE image view/transfer option in addition to Wifi/QRcode remote control
- firmware can be updated wirelessly using your smartphone
- new 17Wh 520 shot BLX-1 Li-ion battery 25% more power (but compatible with BLH-1 battery) and camera has USB-PD charging (9V 3A) as with E-M1 III; No external charger comes with the camera but it can be charged or operated over its USB-C socket;
- IP53 weather rating
- 599g w batt/SD card
- $US2199 / $AU3288
issues
- can't use the touch screen to change menu options
- new menu system may cause confusion especially for those with Olympus cameras
- display can get grainy and briefly lose color whilst focusing in low light
- AI subject tracking still requires you to specific choose what type of subject you want to track - there is not Auto detect mode
- AF+Tracking mode still not optimal (this is the mode you must use in video to get to the AI options)
- as per previous Olympus cameras, Panasonic lens features such as aperture ring and OIS will not work (OIS will work but you can't do Dual Sync IS)
