Canon and Sony lack the incentive to add advanced video features to their mirror-free cameras as it can cannibalize their professional video departments. However, Nikon has no such limitation, so I really hoped it would try to surpass Sony with features like professional 10-bit 4K video recording. I also wanted to see good ergonomics, a 24-megapixel sensor, phase-detecting AF, high ISO capacity and fast recording speeds.
Here it is interesting. In particular, Nikon provided these features with Z6 and Z7, for the most part. In my review, I called Z6 the best full frame mirror-free video camera, thanks to the full meter oversampled 4K video, 1
It also offers excellent image quality, even in low light and faster recording speeds than EOS R. It has a very efficient stabilization system in the body, minimal scrolling mechanism and excellent ergonomics that effectively demand my wish list. Nikon offers a better choice of affordable glass than Canon, and the new mount makes it possible to build incredible lenses like the upcoming Nikkor Noct 58mm.
Finally, Nikon recently released a new firmware update that increased autofocus and improved performance, it is no doubt that buyers feel much better about their investment. As for the disadvantages, there are few, especially single card slot and autofocus performance that are still not entirely up to each other.
Why Sony Still Wins
Shortly after its release, Canon EOS R beat Sony and Nikon's full-featured mirror-free products in the sales of Toko's largest camera store, Map Camera. However, sales shortened shortly after and last quarter, Sony outsold Nikon and Canon combined in Japan, according to BCN.
Camera conversion is affected by all kinds of factors such as market saturation – there are now four full-frame mirror-free systems, for better smartphone cameras and more. But I think there are a few reasons why Sony still beats its main rivals.
First, Canon, who had the best chance of sailing Sony, simply didn't do enough. EOS R (and then EOS RP) lacks features that they should definitely have, such as body stability, full frame 4K video and dual card slots. Since Sony is the rooted player and has two very well reviewed cameras (A7 III and A7R III), Canon should have tried to beat it. It didn't even come close.
As for Nikon, Z7 and, in particular, the Z6, both are powerful cameras. In addition, Nikon has recently released a firmware update that adds autofocus to both cameras while increasing AF speed and accuracy.
Unfortunately, however, many reviewers have discovered that Sony's autofocus system is within both Nikon and Canon. Sony has a great advantage because it builds its own sensors and electronics and has more expertise in designing autofocus software. It is painfully clear how far behind Canon's sensors and processors are, judging by the lack of full frame 4K, horrible rolling shutter and slow autofocus speed.
Even Nikon, who did its best to match the A7 III and the A7R III feature of the feature, could not build an autofocus system that is close to matching what Sony has. Meanwhile, Sony is keeping innovation as it has shown with the incredible new autofocus system on the APS-C A6400. This system is bound to appear on its next generation A7 IV cameras, which will jump even further in front of its rivals. Sony is also bound to respond to its competitors with its next-generation cameras.
As it stands now, Canon and Nikon have not exceeded Sony with their latest models and risk falling further behind the next generation of A7 cameras. If they can't find a way to keep up with the technical race, they are left to fight over Son's scraper in an ever-shrinking mirrorless camera market.
