In this video, we’ll reveal everything you need to know about the Nikon FTZ adapters, as well as answer questions like:
Does the FTZ adapter slow down F-mount lenses? (This is a shocker)
Does the FTZ adapter hurt image quality?
Can you use Z-mount TCs with the FTZ adapter?
Why is the FTZ adapter so thick?
Is there any difference between the original FTZ and the new one?
And so much more! If you’re a Nikon mirrorless shooter, you owe it to yourself to watch this quick 8-minute video!
Quick follow-up.
There have been a few comments here and elsewhere wondering about the AF speed of the gripped D850 + ENEL18 battery and un-gripped D850 + the normal battery and how that affects speed.
I've been saying that I believe the speed is the same, but it was bugging me since I haven't actually tested it. So, I just grabbed the 600E and tested with D850 with and without the grip (all batteries in question fully charged).
Yup, both are the same. 1/2 second (15 frames @ 30FPS).
I still contend that the speeds we're seeing both from the Z9 and and the D850 are simply the fastest speeds the AF motor can get the lens from minimum focus to infinity.
Another quick update. I knew I had tested the D6 and 600mm like this (no TC) and I finally found the clip and checked the time (I
KNEW I had done that test at one point). The D6 speed for the 600mm from minimum focus to infinity
is also 1/2 second, just like the D850 and just like the Z9. Again, I'm pretty sure the 600 F/4 tops out at 1/2 second from minimum focus distance to infinity no matter what camera is attached.
