Even though I own a Pentax SV, I have a small uncertainty regarding compatibility with the Super-Takumar 50/1.4. My memory is that the only compatibility issue is the 8-element ST 50/1.4 with later production SVs having an orange "R" on the rewind knob able to accept that lens and all other variants; early production SV with an orange "R" being compatible with the 7-element variants only.
That being said, notes for the SV and several other pre-Spotmatic bodies in the Pentax Forums camera reviews indicate a general incompatibility with both the 7-element and 8-element lenses for bodies having the green "R". Am I in need of correction or has someone in this group actually used a 7-element lens on an early SV? By extension, can anyone say the same regarding the S1, S2, S3, or S1a?
Addendum: Information regarding use with the K, S, and AP models would also be appreciated.
Steve
P.S. The manual for the SV lists the ST 50/1.4 with no notation regarding compatibility.
