the yellowish is jst few dots or wat? sorry i cant view your photo

can view it rite now. As u mention u tried on another lens it wont have same problem rite? ur 50mm shoot on other image still occurring same issue? then I would suggest bring back to nikon centre or the shop to see what goes wrong wif that lens since it is not the body issue.

Is your white balance set to auto? Try setting your white balance to other settings besides auto or maybe at manual to see whether is it the auto white balance causing the problem?

I think it has something to do with the flickering of lights.

Try to shoot at different shutter speed to see if there's any difference.

for example take 1 shot at 1/200 and another one at 1/30.

Its caused by fluorescent lights. Keep your shutter speed below 1/50s and you'll be fine. The frequency of our power grid is 50hz, so keeping the shutter below that rate will make sure your image is exposed for the entire period of the light cycle.

you can start from around 1/100.

not all fluorescent lights are equal, so if 1/100 is fine then you can try to go higher until banding appears.  if 1/100 is not fine then lower to 1/80.

yes, because you use burst mode.

once for it fires a few so the banding captured is different.

confirm not lens problem. if it's lens problem then it will be consistent.

ever other newbie photographer will discover this sooner or later, that's why you realize "Faster shutter speed" isn't always the best.

Use shutter mode, manually adjust it to 1/50 or 1/100 or higher until you don't see the flickering issues as per your first post.

This is why some newer cameras has anti-flickering feature on the camera, ie.. 7D Mark II

I think it could be dust on your DSLR image sensor. It is important to change your lenses in calm and non dusty place. Unlike old film camera, the dust goes with the film but for the DSLR, the image sensor is always there. Our country is humid and the dust tend to stick and hard to remove. 

It could be a short strand of fiber. Good luck
