p.1 #1 · p.1 #1 · Nikon Z9 - Stuttering / Lagging EVF and Monitor while using AF-C in low light | |
Hello,
first I would like to introduce myself. My name is Michael and I love photography. After long time using a Canon Rebel I switched to the Z6 which I used for round about 2 years. Last week I was able to collect my Z9 and I love that camera.
But shortly after picked it up I noticed a stuttering EVF and monitor while using AF-C in low light at certain shutter speeds. I did some testing:
Take Note:
-For ease, I only speak about "stuttering". Some call it lagging, some call it decreased refresh rate
-Tests were done on FW 2.1 on the Z9
-I used the Z 24-70 at 2.8
-Starlight view Mode is off (on made it worse but it is to be expected and is stated in the manual)
-Enabling / Disabling AF subject detection options didnīt make any difference
-Live View Exposure (WYSIWYG) on or off did not make any difference
-120hz or 60hz refresh rate did not make any difference
Testing:
Low light situation, no people, animals or vehicles. Just a boring room
-Auto ISO (starting from 64 going up to Hi 2, depending on the shutter speed)
-AF-C, pressing the AF button: Single Point AF or Dynamic Area AF S or Wide Area AF S
-Panning or tilting the camera while pressing the AFbutton
1. Back-Monitor:
-Shutter speed of 1" until and including 1/200 -> Stuttering
-Shutter speed including 1"1.3 and lower and including 1/250 and faster -> no stuttering
-Even if you go up to 1/32000 and ISO Hi2, there is no stuttering. Even if most of the scene is black on the monitor
2. EVF:
-Shutter speed of 1" until and including at 1/80 -> Stuttering
(note: at 1/80 it is slightly stuttering. At 1/50 and slower it is severly stuttering)
-Shutter speed including 1"1.3 and lower and faster than 1/80 -> no stuttering
"Normal" daylight situation, no people, animals or vehicles. Just a boring room
-Auto ISO (same as above)
-AF-C (same as above)
I canīt notice any stuttering on any ISO at any shutter speed in the EVF or the back-monitor.
I compared the results to my Z6 (AF-C Single-Point, Dynamic and Wide-S, same shutter speeds, auto ISO) and my Fuji S-10. Both of these cameras had zero stuttering while doing the exact same procedure in the exact same scenarios.
I would kindly ask if you find the time that you would try and see if your Z9 behaves the same.
Thank you very much,
Michael
