Yes, you lose some quality. There' s no way around it. Introduce any glass not
in the lens' formula, and it's cuts image quality. You have to decide which is
more important. Absolute best performance or protection for the front element.
Nobody says you have to keep it on all the time. I don't use one on my ASPH 35
Summilux, but I do on my 75 Summilux, most of the time. Or a Polarizer on the
75. Or naked (not me! the lens) if I am shooting for absolute best image
quality.
