p.1 #18 · p.1 #18 · Testing the sharpness of my Nikkor 70-300mm f/4.5-5.6G on my D3200 | |
could it be user error, something i am doing wrong?
Of course it could, and most likely is.
The lens, on the tripod, needs to be perfectly level when testing focus, and particularly front or back focusing. If you are shooting down toward the ground (which is what it looks like), or up, or sideways, or cockeyed - then the result means nothing. I wouldn't dismiss it, but I also would not worry too much about a decentered lens. That would be highly unusual with a basic, fairly bulletproof, 70-300mm VR lens.
What would be helpful is if you could use View NX-D and check your focus point, and also post a picture with all the exif data retained. You can download and then install the software here for free:

You need to have the camera and lens level to whatever target your shooting. Set the lens at 300mm, VR off, single point AF-S in the center. Remote release or timed release. Put a few things in front and in back of the target your shooting to then see if they are in or out of focus rather than what your shooting.
There are tons of YouTube videos out there that will help guide you through this.
