Introducing the EOS Ra Camera with Specialized Filtration that Delivers Four Times Greater Hydrogen-alpha Wavelength (656.3 nm) Transmittance Compared to the EOS R

MELVILLE, N.Y., November 5, 2019 — In the words of poet Quintus Ennius, “No one regards what is before his or her feet; we all gaze at the stars.” Helping to gaze and capture the beauty of the stars and beyond, Canon U.S.A., Inc., a leader in digital imaging solutions, today announced the company’s first full-frame mirrorless camera for astrophotography, the EOS Ra. This new camera was built off the EOS R system combining new features, such as four times greater transmittance of hydrogen-alpha (Hα) light of 656.3 nm compared to the original EOS R. For astrophotographers and hobbyists who enjoy capturing the detailed splendor of the night sky, the new EOS Ra will be an ideal camera to shoot with.

“Since the introduction of the EOS R full-frame mirrorless camera system last fall, Canon has remained committed to launching a line of impressive and innovative EOS R models and a strong variety of RF lenses and accessories to meet the needs of every skill level of photographer,” said Kazuto Ogawa, president and chief operating officer, Canon U.S.A., Inc. “As a group of photographers who are passionate about capturing what we can’t see with our naked eyes, the new EOS Ra is designed for astrophotographers looking to capture vivid imagery of the night sky.”

Targeting the needs of astrophotographers, the new EOS Ra full-frame mirrorless camera incorporates many advanced features of the EOS R, such as RF mount design, a 30.3MP CMOS sensor, high-precision electronic viewfinder, high-sensitivity, low-noise performance and 4K time-lapse shooting. Optional accessories include an AC adapter kit, which allows the camera to be powered through an AC wall outlet or a battery-powered inverter, a BG-E22 battery grip and three EF-EOS R mount adapters to accommodate the entire range of over seventy EF & EF-S lenses.

Other features include:

  • Enhanced transmission of Hα rays (656.3 nm wavelength) through an infrared cutoff filter, helping to capture high-precision images of the deep-red wavelengths emitted by nebulae in vivid color, without any special camera alterations.
  • A 30x maximum magnification, allowing users to make extremely precise manual focus adjustments*.
  • Support for all Canon RF, EF and EF-S lenses (with the use of an optional EF-EOS R mount adapter), including more than 70 lenses from the EF series as well as RF series lenses, which deliver superb image quality. The variety of lenses, such as the large-diameter f/1.2 lenses, ultra-wide-angle lenses, and super-telephoto EF lenses, among others, are all well suited to help photographers to choose the best match for their specific astrophotography purposes.

Availability and Pricing

The Canon EOS Ra full-frame mirrorless camera is scheduled to be available in mid-December 2019 for an estimated retail price of $2,499.00 for the body only**.

* This magnification ratio applies to the camera only. Not supported by EOS Utility.

Looks like an easy sell for a great niche. A little alteration to the EOS R making a difference to astro photogs. I like this move from Canon.

Now I'm waiting for the their mirrorless PRO. The lack of recent rumors means maybe a longer wait??

Just like the R.

Thanks for the link. We read so many comments from people saying the "R" is not a professional camera because it doesn't have this or that. This test pretty much demolishes anyone claiming that it's not sufficiently weather-sealed to be called "professional" (whatever that may be).

The R did a good job in IR's weather testing. Is there some reason to believe the Ra does not have the R's sealing?
Perhaps English is not the posters 1st language. Things get lost....But that's why we're here!

So this is a good use of Canon's development resources but a dedicated mirrorless body for Video is too much of a "niche" product. :rolleyes:

Actually its an absolute minimal use of development resources - most of which I'm sure remain focused on the multiple FF bodies confidently expected to be seen in 2020.


Grab your camera, go out and shoot!

I didn't expect Canon to reintroduce an astro camera again after so many years, the last one was the EOS 60Da back in 2012. Nice, so people do not have to remove IR filters covering the sensors of older camera bodies.

This is what I’m referring to, some of us live in humid climate and take our camera out on clear days in winter. For a 2500 dollar camera what’s a few 5 cent gaskets in their bodies. IMHO

Don’t get me wrong I love what direction canon is heading with mirrorless and both the RF and M line.
