My latest acquisition is a AFS 400 2.8D
When processing my first batch of photos, I noticed that all of them were a bit blurry. My buddy suggested using the calibration function of my D500. The auto cal didn't work so I Had to go to trial by combat.After nearly a day of shooting and adjusting I found it to work best at a setting of +20 which is the maximum setting. Is there a better way with this lens & camera. Can I send the combo in to Nikon for a lens and camera tune up & calibration???

If it is new, under warranty, then send it to Nikon to recalibrate. Otherwise, it will cost some bucks to do out of warranty. 

 

What manual methods did you try?

 

What I might do is, set a ruler about ten ft away (a few ft outside the closest focal distance), and turn it there. Then set the ruler 20 ft away and compare the results. You will need to shoot and then look at the image, like in LR, where you can zoom in. Use a tripod.


Thanks, Dennis.

Being stuck at home with the FLU I had some time to play with the lens a bit more. I discovered that the lens is much better suited to my D750 or at least it seems a bit more forgiving than my D500. There also is a learning curve for me and the Bazooka. I am so used to my Sigma 150-600 Contemp that I have to rethink my settings frequently.

On the D750 I am only at +7 on my calibration and I am really close. Also experimenting with different focus modes and layouts.

Now that I have a new $8.00 hood it even looks stylish

It really is a back breaker for hand held shots but I have learned a few tricks. I also just got a new gimbal mount for my tripod so I have that to test also.

I think I will be ok with the Crusher.
