Rick,

I just checked both of my M7s with a the 35 Summilux, 28 Summicron, and 
90 Elmarit, and none of the possible combinations show this, either in 
the finder or looking inside the body. I would get your rangefinder 
checked. Does it focus to infinity? Or is this a difference between M6 
and M7 (hard to believe...)?
