Canon is working on to improve the DSLR viewfinder by adding a extra layer Hybrid EVF over it. Adding a extra layer of Hybrid EVF will going to solve all the problems associated to the optical viewfinder in the current generation of DSLR camera.
Advantage of Having Hybrid Viewfinder in DSLR camera
In general the DSLR viewfinder become dead while you are recording a video, because the mirror is flipped up and the DSLR sensor on work, so at that moment the optical viewfinder becomes inactive. One of the biggest advantage include Hybrid viewfinder, is that you can use it while you are creating video from your DSLR.
Introduction of Global shutter in DSLRs, after adding hybrid EVF for DSLR maker it will become easy to go beyond 20FPS or even more than that while keeping your viewfinder active. Since, the flipping Mirror do have limited physical speed and once they reach physical limit it is not possible to use global shutter with optical viewfinder.
Patent Details – Canon Hybrid Viewfinder – Translated from google
The present invention relates to a camera viewfinder, and more particularly to a single-lens reflex camera having a function of both the electronic view finder optical viewfinder (OVF) (EVF)
PROBLEM TO BE SOLVED: To solve problems of an increased size, a complicated mechanism and the like of a camera employing a viewfinder device allowing switching between an optical viewfinder (OVF) and an electronic viewfinder (EVF).SOLUTION: A main mirror (4) that directs a subject image from a lens (2) to a viewfinder and performs reciprocating revolving movement between a subject observation position and an image pick-up position in which an image pick-up device (17) receives light of the subject image from the lens (2) is configured to have both a display function (6) to display, e.g., an image picked up by the image pick-up device (17) and a mirror function to direct the subject image to the viewfinder, thereby realizing: an OVF mode in which the subject image on a reticle (11) is observed with the viewfinder using the mirror function (5) of the main mirror (4); and an EVF mode in which the main mirror (4) is in an up state and a live view image of the subject is displayed by the display function (6) of the main mirror (4) and observed with the viewfinder.SELECTED DRAWING:

Many rumor mills were expecting the arrival of the Sony A7S III camera during NAB 2018 show. But, as I always say… before the arrival of any camera we generally get some strong hints prior to it’s announcement. But, this time everything was completely dry and even trusted Japanese sources were completely silent.
One of the most interesting thing is Sony doesn’t have any new camera registered in the wireless certification agency. That also clearly indicates we will not going to see any new Mirrorless OR pro compact camera from Sony at least for next 2 to 3 months.

A new Hybrid Image Stabilization patent from Panasonic surfaced over the web. That, clearly shows Panasonic is working to improve the image stabilization system. Well, Panasonic is one of the world leading mirrorless makers and they do offer Hybrid IS in most of their cameras. However, they are step behind Olympus Hybrid IS systems and with E-M1 Mark II camera which offer IS upto 6.5 Stops when used with Olympus lenses.
This is not the first time, We have also published Panasonic Dual IS patent a while ago you can check here. And as you can see below I am adding the screen shot of the patent image.
Recent Patent suggest that Canon is planning to introduce Mirrors inside the Canon EOS Cinema Series so, they can also add a optical viewfinder wrapped over the EVF. So, you can get both view at a time, larger mirrored OVF view as well as EVF view.
Understanding The Canon Hybrid EVF Patent
What is Canon actually trying to do, they want to give you more display area by adding a extra layer of optical viewfinder wrapped around corners of EVF. They won’t going to overlap each other, the Mirror will have a cut out around the sensor to cover up the left-over area of the sensor. So when you are looking through the viewfinder
From Mirrorless to SLT – EOS Lineup Journey
Canon latest patent suggest that they are working on a hybrid optical viewfinder for the Canon EOS cinema lineup. The Canon EOS cinema lineup is mirrorless, that is they don’t have mirror inside as of DSLR cameras. By the way despite of having no mirror inside their system the flange distance remains same (Canon EOS Cinema EF Mount Version ) so they can easily adapt the Canon EF Mount lenses without altering the focal length or loosing any feature.
By adding a Fixed Mirror for sure the EOS Cinema lineup will lose their Mirrorless status for sure. And eventually they will going to become a SLT camera with fixed Mirror inside.
Flange distance isn’t a issue , since they are designed to use EF Mount / DSLR lenses.
SLT system type mirror – fixed and non movable
Yes the mirror Canon will going to introduce is not a movable one as we have seen in the DSLR. The mirror inside a cinema EOS lineup will always going to remain fixed at a certain point, So the user can get uninterrupted view of what they are recording.
Image / Video Quality will remain unaffacted, Since the fixed Mirror isn’t covering up the sensor. So literally we will not going to see any change in the Video quality of the camera.
The Canon EOS in my lineup doesn’t actually need a hybrid viewfinder
But why Canon is trying to add a mirror inside the cinema EOS series. well I have seen professional cinematographers those who never look through the viewfinder while creating a movie or short film, they always prefer external display in their work.
