medium format lens help

[fotojen]

I would like to know what lens to use for still life photography with a mamiya 6x7. I usually shoot with large format 4x5 and use a 210 lens.
Does anyone know the equivalent of this in med. format?

Thanks!

I don't know what macro lenses Mamiya offers, but to get the same angle of view as 210mm on 4"x5" on 6cm x7cm it would be around 135mm or 140mm focal length.
