Do the Kenko AF tubes correct the transmitted aperture value with the extension tube's factor? - otherwise it messes with multisegment metering and it's pretty much useless.
Anyway, for this very reason, the "A" variety of tubes doesn't make any sense and we probably won't see it from Pentax. Instead, they'll come up directly with the FAJ tubes, that is if Pentax ever sees in its FAJ customers a potential market for specialty tools as macro tubes.
