Hello, and welcome.
I am a new owner FP5. I am not always satisfied with my pictures but when I checked what the others did with their FP5, FP5 - Pictures Gallery, I realized my skills are quite limited.
So I guess it depends what your expectations and skills are. However, it is hard to expect a fix when something is not broken.
Many people and reviewers reported a significant improvement in terms of camera experience between FP4 and FP5, so again I am not sure why not calling it good.
