I have acquired a Voigtlander +2 diopter eyesight correction 'disk' for my M240, which I believe will fit. This belief is based on the fact that I am told it fits the old film Nikon viewfinders, and from memory I believe the Nikon ones fit Leica. From memory I think I have to remove the original one and replace it. Can anybody confirm that:
1. I am correct; and
2. Is there an easy way to remove the original one short of taking a pair of pliers to it.
Thanks,
Gerry
