Canon EOS Ra leak: Canon accidentally confirms its mirrorless astro camera

38

Two and a half months after we first reported it, Canon itself has by chance confirmed its upcoming full-frame mirrorless astrophotography digicam, the Canon EOS Ra.

Often product leaks emanate from (or, at the least, are disseminated by) on-line rumor websites. On this case, nonetheless, the leak got here immediately from Canon itself, which briefly had the Canon EOS Ra guide listed on its UK web site.

“The EOS Ra is a version of the EOS R designed for astrophotography”, reads the since-pulled literature (noticed by Canon Watch). “Camera operations are essentially the same as for the EOS R,” although the textual content particulars the important thing variations between a devoted astro digicam and a normal physique.

“This camera has approximately four times the transmittance of hydrogen-alpha light (656 nm) as the EOS R. Photographs of subjects that reflect a lot of infrared light will therefore appear redder than they actually are. Also, as it may not be possible to obtain an appropriate color balance or uneven colors may result, shooting normal subjects with this camera is not recommended.”

After all, you may at all times mount an exterior IR lower filter (which basically replaces the IR filter that has been faraway from the sensor itself) to your lens to be able to adapt the digicam for normal images. 

Rumors concerning the Canon EOS Ra first surfaced again in June, shortly after the producer patented a Canon Moon Capturing Mode to allow simpler taking pictures of celestial our bodies.

After all, Canon has a heritage of manufacturing devoted astrophotography cameras. Its first stargazer was the Canon EOS 20Da, launched again in 2005, and its most up-to-date iteration was the Canon EOS 60Da in 2010. 

Based on B&H, “the 60Da is three times more sensitive to this frequency than the 60D.” This makes the EOS Ra, which Canon states is 4 instances extra delicate than the EOS R, a big enchancment on the earlier mannequin.

As well as, the 60Da (and 20Da earlier than it) solely featured an APS-C sensor. So the Canon EOS Ra is the corporate’s first full-frame astrophotography digicam, in addition to its first mirrorless one. After a close to decade-long absence, we’re excited to see what different bells and whistles the following era mannequin has to supply.
