Hi Kurt,
Have you made any headway on this? I am also having the exact same issue you are having with my 800mm5.6 and D6.
I do not have VR on. Its strange because wide open its fine, so even with the 1.25x on, at wide open 7.1, it works fine.
With help of the sales person where I buy my equipment, we found your post. I have logged an issue with Nikon and this sales person is going to ask her nikon rep about it. The latest firmware did not help with this issue.
It sounds like the 800mm or the D6 need a firmware update. Hopefully not the lens as in the past I had to send the affected lens to Nikon for the update to be applied.

I have same problem with my D6 and 800f5.6 fl. Even I have noticed same slow down issue with 600 f4 plus1.4 extender. Also with 180-400 extender engaged.
I have other issues with D6. in continous mode, camera is just refusing to acquire initial focusing in Group or d9 while bird is doing across or coming toward me. Using 3d to initial focus and then switching to d9.
battery is also issue, with 18c getting 1400-2000 per charge while with 18b only 700-1200. Have talked to Nikon Canada, they asked to send battery but will be sending camera also.
One of my friend bought d6 a week before me and he also has problem with focusing, sent camera to Nikon Canada and now camera is with Nikon as they are waiting part from Japan. Issue with focusing unit.His and mine serial # are only two digit apart.
After new firmware update. Mine d6 is much improved. Mostly getting 11-14 with 800, 600 with 1.4 and 180-400 1.4 engaged. I am shooting Raw, continuous with release priority.
Initial focus lock is also improved but still not as my d5 especially d9 and group. Getting better with C1 5x5. Yet has to check if micro focus adjustment after new firmware update will improve initial focus lock
Nikon Canada has replaced my battery 18c(2019) which came with d6 to new 18c (2020). Still has to check if I am getting more shots per battery charge. Osprey are gone south and weather is up and down☹️
With old battery was getting 1200-2000 shots
Hi everybody,
I just registered in this forum to discuss this rather annoying problem. Indeed I have the same problems that you invoke here above.
I am in contact with Nikon Europe to discuss this problem. We are doing tests to determine exactly where this loss of power is in the number of photos taken in one second. The rate decreases as soon as we leave f: 5.6 and beyond that the speed drops to see f: 8 to 7 FPS, f: 11 to 5 FPS.
It was suggested to me to adjust the parameters a1 and a2:
trigger priority and selected for AF priority. To put the VF to off.
I have been asked which XQD card, I use: CFExpress 64 mgo 2X.
According to my tests it has not changed any things I am at the same point.
I await the response from Nikon and return the information to you.
Hi AlainC,
I have given up on this. I am just accepting that if I want to shoot 14fps. I have to be at 5.6 with the VR turned off. When the VR is turned off, it goes down to probably 11fps. Then reduces as you close the aperture. I was testing with another person with this combo and it was exactly the same.
I have found the 600F4 not having these issues.
>> I tested the D6 with the 600mm F4 and this issue does not exist there.
I tested with the 300mm f / 2.8G VRII and did not find the problem.
There is something to do with what the guy from Nikon tells me:
When an E-type lens is used, 14 frames per second are obtained with the aperture reduced to 2 stops from maximum aperture and a shutter speed of 1 / 250s or more in AF-C mode.
I agree, there is definitely an issue, I am getting same results as you are. The other person that I know who has this issue tried to resolve through NPS with no success.
I'm NPS, so that's why we are looking at this problem which in my opinion should be known at Nikon, I just hope that the case will go to Japan to finally have a new firmware ...
I received a response for this problem from Nikon Europe, he replied this:
"Unfortunately we do not comment directly on messages sent on the forums. However, if other users encounter a similar malfunction, I invite you to make them contact our service or the Canadian service to get as much of the case as possible. "
Therefore, I encourage all owners of the same equipment to send an email to their Nikon service. NPS or not, you have to the most people to make things happen.
Thank you in advance for doing what is necessary to make things happen.

i have the lens but not D6 to test/report. Hope the issue gets fixed and Nikon can avoid this with the Z9. Seems the 800FL always gets left behind with new bodies...
>> Seems the 800FL always gets left behind with new bodies...
So I don't know if there is the same problem with the fresnel. I have a friend who has the D6 + the 500mm FL and I didn't notice there was a slowdown at f:8 and more...
I haven't really had any feedback with the other boxes. I used my 800mm with the D4 + D4s without any problems for 3 years.
I had a return to the service after 15 days of work leaving the store, it was the focus ring that got stuck in the cold, impossible to turn ...
Regarding the Z9 we have no info on what it has as electronics, but if the problem Z9 + 800mm 5.6 / E should be the same, you must send an email to Nikon after sales services in your country to escalate the problem.

when D4 was first released, there was AF issues between the 800FL and body. Nikon did release a FW update shortly after. Being the most expensive lens in nikon's lineup, you would think the af mechanism/algorithm be similar among their supertele...

More than that!
When I plugged the D4 to the 800mm I got an ERR message! Cannot use D4.
So the D4 went for repair and from what I heard, Nikon changed the camera's motherboard.
I must say that I was in the first to have this machine and I suffered 7 <=> at Nikon for various problems ...
Yes, the D6 and 800mm slow down somewhat at f/8, but not appreciably.
I conducted tests with & without the TC 1.25 in both Group and Single point AF. The longest it took to capture 14 frames wide open was 993 milliseconds. That works out to 14.1 fps. Stopping down to f/8, the longest sequence was 1019 milliseconds, or 13.74 fps. My battery was at about 75% and I’m at firmware v1.31.
Turning on VR does make some difference in the aggregate frame rate. For my D6 and 800mm..wide open I can shoot 13.9 fps with VR set to 'Normal'.. Stopping down to f/8, that becomes 13.6 fps. I rarely turn on VR, but even if I did, I don't think that negligible impact would concern me at all.
