To know the answer, you have to look at each lens in question, checking the Mamiya spec's for the older AF versions.
There are basically 3 possible versions, besides the much older MF versions.
1. The Mamiya AF version that goes back as much as 12 maybe 15 years in age. This includes the 35mm, 45mm, 55. All of these lenses have been rebadged as D versions over the years.
The 35mm and 45mm both have the same number of elements and groups between the D and non-D versions. Supposedly the D versions have "better" QA and should have possible closer tolerances. Not sure on how much I believe that as I have tried both the 35mm D and 45mm D and own both the 35mm and 45mm non D AF versions. I did not notice any marked differences.
The 55mm (not sure if it has a D version, but for sure has the LS version). The 55 AF is one of the best all round lenses I ever used with my DF. Very sharp but also considerably shallow DOF, even at F11. Wide open very shallow.
The 80mm D added the chuck to allow you to turn AF on or off on the lens, it's a rotating ring. I own this lens and it's an exceptional lens. I also owned the previous AF version and my D version is better.
The 55 LS seems to be a totally different lens as does the 110LS, I have not used either on of these, but all the reports are excellent.
The 28mm AF, D and LS all pretty much are the same, just look up the numbers of elements/grouping. For the price, I am not very keen on this lens, and traded mine in for a 28mm Rodenstock tech lens, and have never regretted this, only wish that Rodenstock had developed this lens around a 90mm IC.
The 75-150, still stands out as my by best, sharpest all round great lens. I have the AF non D version Mamiya branded version. Mine is sharp throughout the zoom range and besides being very heavy, I love it. Sadly I don't use it that much anymore since I have switched over to the Tech solution.
The 240LS appears to be in a class by itself, expectational lens. It's on my wish list.
