I dont shoot landscapes. I mainly shoot portraits and Group shots .
I use f5.6-f8 I cant seem to find the Differences between them. Thank you

Outdoor portraits with studio flash would benefit from leaf shutters, but what lens do you refer to as non d ?

There is the older Mamiya 55 mm f 2.8, which predates the silver ring LS version.
It has no AF clutch, and cannot/should not be focused manually on on XF.

Ty Anwarp. Yes. the Mamiya 55 2.8 is the Older version and was told to go with the D version.
