The 8 element Tak works fine with the MX. I use that combo frequently.
Originally posted by Mikehopton As I understand the 50mm 1.4 8 element M42 lens was not recommended for
use with cameras other than the new Spotmatic which it was launched with. That is,
the earlier M42 mount cameras may interfere with the protruding rear element.
Not quite. The 8 element Takumar was released well before the Spotmatic line, and all Spotmatics are compatible. The compatibility issues are with
some earlier S-series bodies (S2, S3, S1a etc) that had a different design for the aperture push lever. This isn’t model specific (ie. some SVs are fine while some will jam), and the easiest way to tell is the colour of the ‘R’ on the rewind crank. Red R means all is good, green R means it won’t work*.
*Note that all Spotmatics have a green R but all are compatible. The colour only has significance on the S series.
