1.Prepare CA1 and 2″(48mm) Filter.
Back focus distance of CA1 is 44mm (Same to Canon DSLR) and it’s only valid in case of you install a filter (1.8mm~3.0mm thickness glass can be acceptable) in 48mm thread of CA1. If you use CA1 without any filter installation, your lens may not get infinity focus.
