So i just watched a video on fine tuning your focus on a lens. So i figured why not give it a try! Now i just got my D750 back from the flare fix a few weeks ago and so i dont have results of before vs now. Anyways so i printed out the focus chart, layed it flat on a table and shot in the center as described at 1.8 while shooting at a 45 degree angle. I find that for this lens i need to push the focus up all the way to 20 in order to get proper center focus with this lens. Now mind you i just got in a tamron 70-200 2.8 and that only needed a +9 adjustment. I then tried the nikon 24-85 3.5 (which isnt as good to compare i know because its at 3.5 but i wanted to compare anyways) so then tried at and it seemed to need +7.
So my question from what i see is:
A) since there isnt much of a change in fine tuning for the rest of the lens i am to assume that the 50mm is more of the problem then the camera is?
Has anyone else had this problem at 1.8 on their 50 or is this super out of spec?
C) Suggestions as to what to do
Thank you all so much for your time!
