Since these images were obtained (Metz catalogue 94-95), Metz has
updated the SCA 3701 (Nikon) for compatibility with 3-D metering and
made a SCA 3000 for the Leica R8 (SCA 3501, if I am not mistaken).
I don't know if there were other changes/additions to the range.
SCA 3101 (Canon)
SCA 3301 (Minolta)
SCA 3401 (Nikon)
SCA 3701 (Pentax)
