: “Technically speaking, under EF design rules this lens would not be practical because of the different design parameters having an impact on all aspects of the optics and size.

By developing a new algorithm that analyses the captured images and reduces errors, then incorporating it into Canon’s EOS VR Utility software and the EOS VR Plugin for Adobe Premiere Pro 1, we were able to reliably create accurate VR imagery, even when using an interchangeable lenses on different cameras.”Ĭanon Europe: Why has Canon decided to release this lens now? Was design not a possibility in the past, or is the market trending in this direction?Ĭanon Inc. “The next challenge, was the evaluation method of the stereo lens to ensure a correct stereoscopic image, made more challenging by the fact that the (interchangeable) lens and camera combination could cause errors between different cameras.

These are combined like a puzzle within the size constraints of RF lenses but resulted in the development of a high-performance L-series lens that our professional Canon users have become accustomed to. The challenge was solved using various components such as a prism bending optical system that ensures the 60mm interpupillary distance required for 3D 180° VR shooting, an electric iris diaphragm "EMD", an optical adjustment mechanism that makes use of a large-diameter RF mount and a dust-proof and drip-proof structure. : “Overall, it was to develop a fisheye lens that achieves an optical performance that meets the requirements of an L-series lens, while ensuring a baseline length of just 60mm. “As a result, we brought together the knowledge of engineers who have been involved in Canon’s optical products for many years and who strongly believe in the value of a 180° VR interchangeable RF mount lens, to work together to solve the large number of technical challenges and to realise the benefits of the Canon RF 5.2mm F2.8L Dual Fisheye lens.”Ĭanon Europe: What were the biggest challenges you faced when creating such a ground-breaking lens, and how did you overcome them?Ĭanon Inc.
“If you use a dedicated VR camera, then the creative options for that camera are limited to VR shooting alone, but the building of a dedicated rig, using multiple cameras, is not an easy solution either, limiting it to some professional users. So, it was the development process itself, to design an interchangeable lens with an RF mount and the possibilities that brings, that excited us most. However, these shooting methods could not take advantage of the Canon EOS R System’s creative possibilities and use of interchangeable lenses. : “Until now, the only way to create an 180° VR image has generally been to use a dedicated VR camera or to build a dedicated rig with multiple cameras. The Canon EOS R5 is the ideal partner for the Canon RF 5.2mm F2.8L Dual Fisheye, thanks to Canon's latest firmware update, which adds VR functionality and compatibility.īefore diving into the technology behind the EOS VR SYSTEM, we asked the team of engineers to share the motive behind, challenges faced and the future direction of VR for Canon.Ĭanon Europe: What excited you the most about designing the Canon RF 5.2mm F2.8L Dual Fisheye lens?Ĭanon Inc. Attached in the same way as any regular lens to a compatible RF mount camera, the lens makes use of the camera's 8K video capture capability to create a single high-quality, high resolution stereoscopic 180° VR image file, which is easy to capture and process using Canon's EOS VR Utility 1 software. So how does this lens work? As its name suggests, the Canon RF 5.2mm F2.8L Dual Fisheye projects stereoscopic left and right eye images onto a single image sensor. The field of view is also perfect for a wide range of applications, including education, documentary, travel, retail and entertainment. With the three-dimensional stereoscopic action focused to a 180° field of view where viewers can look up, down, left and right through a compatible headset or viewing device, the Canon RF 5.2mm F2.8L Dual Fisheye lens creates an incredibly immersive experience, especially when compared to monoscopic two-dimensional alternatives.
