It could be lens lost calibration. Try this and tell us. Use f5.6 or greater number like f8 etc... Take a photo of a white text with black background, this will show you ghosting effect in the edges of the letter. If this happens, one of the components of your lenses is out of the center. This can happen due to a hit, etc... Let us know. Regards

You appear to be using your lens (100-400/5-6.3) with the aperture wide open. I would expect the glow in your photos to be significantly reduced or absent stopped down to about F8. Many lenses "glow" when used wide open, especially in bright light with high contrast. It is likely associated with spherical aberration and is typically reduced or completely ...

All lenses are debased by aberrations, two of which deal with color. The lens maker endeavors to mitigate by crafting the lens using multiple lens elements. Most commonly, chromatic aberration displays images with a rainbow colored edge effect. This is caused by the fact that each color has a slightly different focal length. The violet image falls closer to ...

You've got a dirty lens. First, alcohol. IPA, ethanol. Use that with a microfibre cloth. That should dissolve the oils, but you want the cloth to pull it off of the glass and into the cloth. Don't reuse sections of the cloth. Then, a little Deionized water and soap- a tiny tiny tiny smidgen. Again, just enough to be a surfactant. Wipe the lense elements ...

The fact you're seeing this with two very different bodies suggests to me it's in the lens. Long zooms tend to have a bunch of elements (anywhere from a dozen to twenty, in my experience). No lens coating is perfect, and no lens surface is perfect. Every time light passes through an air-glass or glass-glass interface at an element surface, there's a small ...

The D7100 body that this lens works with has a focus motor built into the body that connects to a mechanical coupling on Nikkor AF lenses and third party equivalents to move the focus elements in the lens. Your D3300 does not have a focus motor in the body. To use autofocus your D3300 requires that you use Nikon AF-S or AF-I lenses or the equivalent third ...

Best guess, based on a quick Google*, is that this lens requires that the camera has a physical focus motor & will therefore not work in AF mode on a camera without one - essentially the entire D3xxx and D5xxx range. This issue is not 'fixable' without changing to a camera that does have this mechanism. *Guess based on this Amazon link, but feels ...
