We're usually on the same page, and without viewing this video the following points are obvious:
- Either you spend more on the body (Z8) that accepts third party lenses or you spend more on (quirky for a Nikon user) RF lenses. (Z8)
- The smaller size, weight (.4 lb lighter,) and fully articulating screen on the R5 are significant. (R5)
- The R5 is now rather dated and this isn't really a fair comparison. I can't stand MARK. Just label them with the year already. R5'20, Z8'23, DONE! (Z8)
- What camera fits into your digital work flow better? (R5 if you use Lightroom)
- What camera is more likely to improve with firmware updates? (Z8 landslide)
- The Canon has a better EVF and AF tracking implementation, but I had no trouble with the Z8's even with adapted e-mount glass. SORRY, the R5 Canon has instant eye-tracking that can be programmed to the *. This is invaluable!
- Canon/Sony let you remap the dial-pad to four buttons with just about any setting you want. (R5)
One of these has a much more professional vibe to it, and that goes beyond the size.

Jan's presentation was fairly balanced and it appeared to be addressing, though not exclusively, current Canon users. As a afficionado of both systems, Jan I differ on a few accounts (mainly buttons and programmability). As he observed, the only reason one would consider switching from Canon is because of Nikon's glass. That we agree upon. Canon does offer a wider array of bodies to choose from, though for me, it's all about the lenses and that's what we should be talking about. Canon has ignored mid-range, cost competitive, innovative, long lenses. Sure, they have the 600 and 800 f/11 though for serious WL photographers they simply are not practical except in very limited circumstances. Rather, Canon appears to have focused on entry level (R7 + these lenses) or on the high-end glass such as the RF 100-300 f/2.8, RF 200-500 f/4, & RF 600 f/4. All of these lenses will cost you your first born.
In contrast, Nikon has many exciting, relatively affordable WL lenses including the 800 f/6.3 PF, 180-600 f/5.6-6.3, 400 f/4.5, etc. (not including 3rd party). While some claim that Jan's comparison isn't fair because the R5 is "dated", that is precisely the issue. The R5 is a great camera, and it performs marvelously, though I find that the glass is the bigger factor for consideration. Sure, I can slap an older big white on the R5 with an adapter and it is going to perform well, though it is likely to be heavy, may have some limitations in FPS, AF field size, etc. Additionally, the Nikon VR is so amazing and impressive that my Nikon images are comparatively sharper than my Canon ones, shot in real word conditions.
Overall, the Canon AF is easier to navigate than Nikon, and as Jan indicated it does tend to identify and track better overall. Overall, the differences between the AF are relatively small and are, for the most part negated by the lens offerings and VR. It is likely that the R5II will likely offer some improvements at a price tag approaching the Z8 though Canon doesn't have an answer regarding the lenses.
