All of a sudden when I went to mount my beloved Panasonic Leica 25mm f1.4 to my Panasonic GH3 it wasn't the smooth clicking I was used to feeling, rather a gritty and grinding feel and the GH3 tells me the lens is not on all the way. When the lens is on all the way it feels almost like I forced it a little bit and is a tiny (only a little bit) loose. I do not want to damage the camera's mount but I never have had this problem before with the lens so it is weird. I did just get a new lens and mount it on to the camera (Olympus 40-150mm) if that affects anything. Pictures are attached of the camera's mount and lens mount if anything can be detected. Do you think it is a problem with the lens mount, because other m4/3 lens mouth smoothly? It is funny because this lens worked fine yesterday and nothing has happened to it in between.
