Erratic autofocus is often caused by dirty contacts in the lens or body.  You might try cleaning them and see if it helps.

These are the aautofocus settings I used: AFC Wide L Subject Detect Animal AFC, AFS Priority:  Focus Blocked Response 5 Subject Motion  Steady Focus Points All AF Activation Shutter/AF-On Limit AF ...

I have recently upgraded to V2.1,  My focus success with V1.1 was abysmal.  Have not yet tried the new version. Maybe today.  Could you share your settings related to autofocus?  That would help ...

I will just have to struggle along with the 800 F5.6 a while longer.

I have had the Z9 for about 3months, coming from a D810, which I still have.  It has been a tumultuous 3 months due to an injury my wife sustained, taking care of her and her needs.  Not much time ...

This happened to me, also. I conceived the following scenario to explain it. Don't know if it is real. I had used the old, standalone version of Nikon Transfer for years. Then I acquired a Z9, and ...

I have taken many hummingbird photos, mostly with a D810 and several very long lenses, even with a Z9.  I have seen birds completely exit the image area reacting to the noise/motion of the ...

I used close up filters several yearS ago when I could not afford a macro lens.  While I cannot describe in detail, I did not like the effect. I used a couple of brands and strengths.  Check out ...

Another helpful idea would be to post a screen shot or snip showing the focus point used for the original photo

OK, a crazy idea.  TAke a shot of a static shot that evokes the problem, then rotate the camer and lens 99, 180 and 270 degrees.  See where the problem moves.  A tripod may be needed.  This would ...

I have both the D800 and D810.  It would surprise me if either had eye auto focus.     The D810 is definitely a better all round camera, especially in the focus area.   Because the D800 has been ...

MFD is only part of the closeup story. Equally important is the maximum reproduction ratio. For most oof the exotics that ratio is about .2, meaning something one inch in real life will be about ...

I have the F mount 800 and frequently use it with the 1.25 TC.  I bought it in 2014, I believe.  I have yet to see image deterioration due to atmospheric conditions when shooting birds.  The birds ...

I have the Z9 and wonder if having IBIS on would help.  It would eliminate or reduce camera shake which could be contributing to the problem.  So far, my  keeper rate is about the same as with the ...

Thank you for all of the replies.

I just acquired the Z9 and FTZii. I have a few long F lenses:800mm, 500 PF, 80 to 400.  I also have a 20, and 24 to 70(the original).  After looking at all of this and the FTZ, it seems to me that ...

In following discussions about the advantage's/disadvantages of using a TC, I have often wondered if the answer lies in the size of the image of the subject.  So, for example, could it be that the ...

Why not set up a Focus Tune type target.  A good focus target i the center and a ruler o the diagonal on the side.  Focus on the target and look for the point of best focus on the ruler.  Either ...

The first version of this lens was Nikon's first VR lens. It was one of the "screw driver" lenses. where autofocus was driven by a motor in the camera body and sent to the lens by a connector that ...

I have been reading this thread with interest.  I have never heard of the 500 f5 mirror lens.  I have heard of the 500mm f8 lens, both versions.  I have the second version.  While it appeared ...
