![]() A finished, 4K resolution 4K video file can be assembled from individual images, taken at user-defined intervals from 2 seconds~99 hours, 59 minutes, 59 seconds. Even more attractive for some users is the availability of 4K Time Lapse recording, in camera. Users can set-up specific, frequently-used commands, and with a touch of either side of the bar, or a swipe along its surface, make setting changes - again, with less risk of camera movement or shake than by pressing conventional buttons.ĮOS Ra opens the door to 4K video recording, at up to 30 fps, and at ISOs reaching 12800. This unique, touch-sensitive control on the back of the EOS R camera is carried-over to the specialized EOS Ra model. ![]() Most commands can be entered by simply touching the LCD screen, minimizing risk of subtle shake or camera movement that can occur from pressing buttons. Another important advantage: easy shooting during vertical shooting - something often rather awkward on some competitive cameras with tilt-only rear screens. And with Canon EF lenses, mounted via one of three optional Canon lens mount adapters, users can expect the same excellent optical performance they’ve achieved for years with Canon EOS DSLRs.įully-articulated LCD screen, which can be especially helpful if the camera is mounted to telescopes. Canon engineers are excited by the possibilities of using many of the superb RF lenses in the challenging astrophotography environment, including wide-aperture lenses and L-series zooms. This opens the door to two outstanding lens systems: Canon’s dedicated RF lens series, and via an accessory lens mount adapter, over 70 choices in the Canon EF lens system. With its low-light sensitivity, and ability to perform AF (with many lenses) over 100% of the height x 88% of the width of full-frame images, achieving fast initial focus with RF and EF lenses is always an option for the night-sky photographer. Silent Shutter operation activates entirely electronic first and second-curtain shutter operation, minimizing risk of vibration from mechanical shutter action in high-magnification, tripod-mounted situations.Ĭanon's excellent AF system is carried over to the EOS Ra camera. This can mean even more night-sky detail, when viewing through the electronic, eye-level finder. 2.1 million dot resolution for the camera’s LCD screen). The EVF becomes a very useful alternative to viewing on the LCD screen, in part because it can minimize interference with a user’s night vision in dark environments. The EVF is a high-resolution, OLED design with 3.69 million pixel resolution (vs. This includes compatibility with the 5x/30x magnification feature, mentioned above. This alone brings tremendous advantages in low-light viewing, relative to the optical, eye-level viewfinders of previous EOS digital SLRs. The ability to access high ISOs can mean faster shutter speeds in some night sky situations, with less risk of blurs from shake, or star/planetary movement.įirst and foremost, the EOS Ra has the same large, electronic viewfinder as the standard EOS R camera. previous Canon astro-dedicated cameras: exceptional control of high ISO noise at settings typical in many astro situations (ISOs such as 16), and ability to extend high ISOs up to 40,000 when needed. 4.3 microns square.High ISO performance brings two advantages, vs. ![]() With a smaller APS-C size image sensor, the previous Canon EOS 60Da (18 million pixels) had a smaller pixel size of approx. ![]() This is especially useful for wide-angle terrestrial photography of land and night skies, opening the door to many different lens options which provide true wide-angle coverage. Pixel size on this 30.3 million pixel sensor is a relatively large 5.36 microns square - an important consideration to serious astrophotography users - since smaller pixels tend to introduce more high ISO noise. Canon's first astro-dedicated camera with a full-frame image sensor.
