which 645 to adapt?

[BIGOAK]

hello

anyone have any input for which kind of adapter would be best to invest in given the follow wants (+) and want to avoids (-)?

+a good macro

+fast lenses (<2.8)

+good character

+autofocus (ideal, not a dealbreaker)

+good selection of focal lengths

+options wider than 30mm

-excessively high cost

-vignetting

-zooms not required

 

been considering the mamiya and the CZ adapters, but am open to ideas for FF systems if you can recommend some with UWAs that don't vignette.
