Finally we have the major specs of the Canon EOS Ra camera. Let’s take a look at the major specs of the camera. It features almost same core specs as we have seen in Canon EOS R camera.
Canon EOS Ra Major Specification [Rumor]
- 30.3MP Full-Frame CMOS Sensor
- Infrared Sensitivity–Astrophotography
- DIGIC 8 Image Processor
- 4K30, 24 Video
- C-Log & 10-Bit HDMI Out
- Dual Pixel CMOS AF
- 3.69m-Dot OLED Electronic Viewfinder
- 3.15″ 2.1m-Dot Swivel Touchscreen LCD
- Expanded ISO 50-102400
- Wi-Fi and Bluetooth, SD UHS-II Card Slot
- Multi-Function Bar, Dual Pixel RAW
Modified infrared filter and a low-noise sensor with heightened hydrogen-alpha sensitivity. These modifications allow the camera to capture magnificent photographs of “red hydrogen emission” nebulae and other cosmic phenomena.
The major difference between the EOS R and EOS Ra is the modified IR cut filter. Canon has altered the filter to provide the Canon EOSRa with greater infrared light sensitivity and enabled it to achieve hydrogen-alpha light transparency. Hydrogen-alpha, also referred to as H-alpha or Hα, is a very specific red visible spectral line created by hydrogen, with a wavelength of 656.28nm. This red visible line in the spectrum occurs when hydrogen electrons fluctuate between the second and third-tiered orbits (or energy levels) of a hydrogen atom (according to the Balmer Series). When they move between these levels they absorb or release energy, and this emission and absorption of energy occurs at 656nm.
The IR cut filter modification of the Canon EOS Ra helps to allow as much light as possible to pass through this narrow bandwidth at the H-alpha frequency. The modification essentially allows you to photograph reddish, diffuse nebulae and other astronomical phenomena in a clearer, more brilliant manner—void of the IR attenuation associated with traditional hot mirrors and other IR-blocking technologies on most cameras. The need to photograph light at this wavelength is paramount because the color of light emitted from nebulae is strongest, and most pure at the hydrogen-alpha line. The color of this light is outside the parameters of the visible spectrum, and our eyes, or camera, cannot accurately render this light without filtration.

Finally the images of the Canon EOS Ra camera leaked. Now we are waiting for it’s official announcement which is about to happen in next few days. As we have said earlier also in our post the camera will have almost same core specification as we have seen in the Canon EOS R camera. Except a modified low-pass filter which will be more sensitive to infrared light.
World First FF Mirrorless Camera Dedicated for Astrophotography
We have no FF Mirrorless camera dedicated for Astrophotography. In Nikon we have the D850(A) FF DSLR dedicated for astro work. So. literally Canon will soon become world first and only camera maker to have FF Mirrorless camera for astrophotography. Sony A7R IV and A7R III mirrorless camera know as star eaters, Hope Sony and Nikon will also join the astro race soon with capable cameras.
More Images of the Upcoming Canon EOS Ra Camera
We will update you soon as we get any new information.

Why camera makers are investing time and money in R&D of fan based cooling system in camera. Even if the Fan cooling unit used for external body cooling purpose only, then also there is great chance that air rotation for prolonged period of time in camera body may attract unwanted dust particles to camera body & lens unit if we are shooting in streets. And just in case if we are shooting in humid or rainy season what will going to happen then ?
Patent Images
The cooling vent looks like optional module and it can be added when it required.
Take a look at the text from patent
Conventionally, even in a digital camera, heat generation in an image sensor and an image processing circuit has become a problem due to an increase in pixels of the image sensor and a high frame rate of a moving image. In addition, the camera itself is required to be miniaturized, and there are few parts that release heat. For this reason, there is a limit to heat countermeasures by using heat transfer members that have been conventionally used to diffuse heat to the respective members and making them uniform.
For this reason, forced air cooling using a fan or the like has been proposed, but if it is built in, the image pickup apparatus itself may become large.
Why not Liquid Cooling as we have in Smartphones
Some Smartphones makers are now using liquid cooling tech to combat heat generated by the processor, when phone is being used actively for hours. Chines smartphone maker Xiaomi uses liquid cooling tech in Poco F1 and in Black shark model. Korea based Smartphone maker Samsung also uses liquid cooling tech in Galaxy S7 and other flagship models to prevent overheating. Samsung developed a method of water cooling that uses a copper thermal heat pipe to disperse heat away from the CPU, especially as the chip works harder.
We have published this patent on December 17th, 2017, in this patent we can clearly see that Canon engineers were working on a Canon 5D series future body (may be Canon 5D Mark V) to combat camera heat.

According to latest rumors surfaced over the web via anonymous sources. Fuji X100F successor (Fuji X100 V) is expected to arrive in early 2020, if everything goes on scheduled. Several prototypes of the camera do exist and being tested in the wild. The model with tilting touchscreen and 26MP BSI CMOS sensor is set to be the successor of X100F camera.
The model name of the camera isn’t confirmed yet, most probably the successor name is X100V. We will update you soon as soon as we get any new information.
Take this info with grain of salt.

In a latest firmware update Canon enabled 24fps option in Canon 90D camera. 24fps frame rate is missing in latest Canon DSLRs and Mirrorless camera including recently announced 90D Camera.
Firmware 1.1.1 adds 24p video in both full HD and 4K in Canon 90D.
Firmware Version 1.1.1 incorporates the following enhancements and fixes:
- The option to capture both 4K and Full HD movies in the frame rate of 23.98p has been newly added
- Fixes an issue where error code “Err 01” may be displayed when using EF 85mm f/1.8 USM or EF 100mm f/2 USM lenses.
