Summilux M 28mm f1.4 quirks

I'm looking for some feedback. My one year old Summilux M 28mm f1.4 has 2 quirks and I am curious if they are simply characteristics?

1. The front portion of the lens, the FLE section, has some very very slight up & down movement that is barely audible, but audible if I move the camera/lens in a up & down motion.

2. The focus ring is much stiffer than my other M lenses (50mm & 75mm)

The lens functions and focuses perfectly.

Does any one have a similar situation or advice?

Thanks.

The floating element is toward the rear of the optical system.

That’s not good, send it in

My 28/1.4 focusing is also slightly stiffer than my other M lenses but its still fine for my taste.

I took the lens to my local Leica Store. It was sent to N.J. for a CLA. I should have it back in 4 to 6 weeks.  Leica always handles things very professionally.

i realized that focus stiffness can vary depending on environmental temperature, especially on the brass lenses
