    I’ve been saying this for 3 years, we need hybrid EVF+OVF for DSLR’s, so good to see Nikon and Canon working on this. There’s still life left in DSLR’s

    Great find… DSLRs do need Hybrid OEVF at the moment.

    Wait – I thought Optical VFs were “perfect”
    Goes to show that marketing of this 1930s technology (the SLR) has not been truthful.

    Outdated OVFs clearly need a lot of help from modern techniques that Mirrorless have been using for nearly ten years.

    Why bother with a mirror any more? Mirrors solve a problem that was solved better, 10 years ago.
