I love my Z8 and Z9 for sure!
But comparing these with my sony a1 , I can assure you that the focus acquisition in fast and far wildlife subjects is much better with the sony cameras.This is clearly seen already for BIF.
This what all impartial reviewers are saying, Nikon is still lagging.
Maybe you should also watch the part of the video that is about video autofocus. And perhaps stop by the part about video stabilization as well.
Maybe it’s a case of cognitive dissonance, and that’s why nobody’s talking about it, but Nikon appears to be the better choice for video.
First of all, Jan's video is Nikon vs. Canon, not Sony.
Second, Orsonneke seems to talking about stills performance, not video.
Third, starbase218 refers to Nikon as "the better choice for video." This is largely confirmed by Jan's video, but I think the topic is stills AF.
Now, in Jan's video, at 9:00, he shows Nikon's struggle with BIF against a waves background.
Again, this is about stills.
From the transcript:
…when it
comes to action photography this is
where we see the biggest differences
between these cameras especially against
busier backgrounds or water backgrounds
the Nikon cameras struggle with Canon
seems to be able to identify the subject
and just stick to the subject without
being distracted by like waves in a
background for instance
bird didn't fill a large portion of your
frame it seemed like both the Z8 and the
z9 just couldn't identify what's the
water what's the subject what do you
actually want me to focus on then that
would just jump off from the seagull
onto the water back onto the bird and
back onto the water so it was quite
difficult to focus on anything with the
water background the further away in the
background the
it was for the cameras to nail the focus
and I still got some amazing shots but
overall it was a little bit of a
struggle I wasn't quite sure how the R5
would perform in a similar setting but I
took it there the other day and the
differences were quite dramatic there's
an example of this gannet here for
instance it's tiny in my frame but the
R5 picked it up without any issues and
tracked it a long time against the wave
never once jumping onto the wave and
back to the bird it just just stick to
the bird without problems at all this is
definitely a trend I saw with the R5 at
that Cliff this is the biggest
difference for me between the Nikon and
the Canon autofocus at the moment the
Canon over the focus just seems to know
this is the subject so it just tracks it
and it doesn't get distracted by
anything else coming into your frame or
the waist behind the bird where's the
Nikon autofocus doesn't quite seem to
know what you actually want from it and
jumps on and off a lot more so while the
Canon autofocus seems to still have a
little bit of an edge in subject
recognition and being sort of certain
what to track both of these autofocus
systems deliver fantastic results in the
field and I wouldn't have any hesitation
using the Nikon autofocusing system but
at the same time in direct comparison
Canon definitely stands out at still
having a bit of an edge also because
it's so much easier to set up and to use
Nikon definitely has one advantage
though when it comes to action
photography and that is the blackout
free shooting in the viewfinder with
Canon it's a bit more of a slideshow
whereas with the Nikon cameras you get
nice and clear views and it's much
easier to track to birds…
