Exploring Canon's dual lenses - a remarkable technology not just for virtual reality

What are Canon's dual lenses used for? This piece of cutting-edge technology has not gained much attention from photographers, so I decided to explore it. It can also be used outside the world of virtual reality - for creating remarkable videos, for example.
In the video, we work with the new Canon RF-S 3.9mm F3.5 STM Dual Fisheye lens, as well as the older professional model Canon RF 5.2mm F2.8 L Dual Fisheye.

I got the 5.2mm dual fisheye lens for canon's full frame lineup and its a really good lens to capture reality. In fact combined with a r5c you can record 8k 60fps vr videos, where others can only do 30fps. Canon is saving vr video with that lens. The newer one (3.9mm) is a bit flawed though, you only get 144°fov, compared to 180° and the cameras that its used on cant even record in 8k. Its a bit of a shame.

The R5c is not giving you actual 8k. Far from it. It is physically impossible. Canon is just stitching to an 8k output. This lens is a smart move as the ppd will probably be on par with the 5.2mm. If an 8k aspc sensor ever comes out it will blow past the 5.2mm.

@@JFreshInEffect I dont know, it records a bit over 8k, but the lens is projecting 2 circular images on the lens, which does result in lose pixels. So when it gets converted to equirectangular projection you are not getting real real 8k. It is the same for this new 3.9mm lens though, you dont get the full sensor.

Isn't that for making 3D photos?

Hi, primarily, it is meant to be used for videos for VR headsets, but I really liked the option to create "normal" videos for "normal" viewing on RUclips - that's the reason why I made this piece... Jan
