When doing the mount swap you will need a clean environment and a stable flat surface.
All the parts and tools you will need are provided in the conversion kit.
Its important to take your time when doing this conversion to minimalise any risk of damaging the lens
Even when going slowly the process is fairly quick to carry out & should take approximately 15 minutes to do.
You can keep the mount in the packaging at this stage to protect the anodised rear of the mount from marks.
Place the Fujinon MK lens with the front of the lens (with the lens cap on) facing your work surface.
You can then use one hand to support the lens and the other to remove the screws.
The tolerances are very tight, so it has to be aligned perfectly perpendicular for the mount to fit.
Make sure that the optic tension shim sits correctly inside the DSMC > Fujinon MK Mount.
Take your time with this section as the rear element of the lens is exposed.
Apply a small amount of pressure onto the mount, so that it seats with the lens correctly.
If the macro adjustment is not easy to move, check the rear optic tension shim has seated correctly
If not seated undo step 1, re-seat the optic tension shim and redo step 1.
