All "neutral" density filters have some shift. These are very minimal. You can see a review comparing these on youtube. They have less color shift than a much more expensive competitor. It is easy to correct if desired using custom white balance or white balance adjustment in software. They are consistent across all of the filters in my experience.

Hi, sorry, what do you means the filter frame ? The filter frame made by aviation aluminum with CNC-non slip design.
