Hi folks, first post so go easy. I just got a GH2 today (body only - I opted to pick up the Panasonic 14-45mm separately) When I attach / de-attach the lens the friction between the mount and the lens feels a little tougher and 'scratchier' than Nikon / Canon DSLRs I've owned. It takes a little more effort to screw the lens on than I'm used to. The best way to describe it is that Nikon / Canon lenses I've used feel lubricated and very smooth when attaching to the mount. In contrast, the GH2 and lens feels a lot more dry. It still clicks into place fine and works perfectly. I'm just concerned that this friction is not normal and will eventually damage the lens / mount. Has anyone else noticed this? Thanks in advance.
