I just got a new 4x5 with GG and fresnel. Are there considerations with focusing due to the fresnel?

The optical grooves on any Fresnel lens affect the ability to use any magnifier. This and a long list of reasons is why any Fresnel "brightness" improver can work against the photographer.
Stopped using any fresnel decades ago for that long list of reasons. IMO, best is very fine grade ground glass precisely matched to the film holder's film location.
