Bellows are too awkward for words.... If the lens is put at nearest focus, the floating element design is optimized for close-focus, and should be
good enough even on long tubes at smaller stops. The TC14A and TC201 also work well enough (not the best I have seen, though), as do the TC14B and
TC301 with tubes to provide glass clearance. The 4T achromat is also
worth a try, as is the Sigma achromat made for their 90 macro (can be combined with tubes/converters at f11-16).
