SV +1, my favorite pre-spotmatic camera.
Excellent 'shooter' camera from that era (S1a too, which is nearly the same camera).
> Any other lenses from that era I should pick up? <
Super-Takumar 35/2.0
Super-Takumar 24/3.5
Super-Takumar 85/1.9
Super-Takumar 135/2.5
Use hoods with all of these.
If your SV is a green '
R' camera,
DO NOT mount any Takumar 50mm/1.4 on it. Carnage will ensue
If your SV is a red-orange '
R' camera, then no worries about using any Takumar m42 lens.
My favorite, most often used, lenses that I shoot on my SV (not exactly that era, early 1970s vintage):
S-M-C Takumar 28/3.5
S-M-C Takumar 35/3.5
SMC Takumar 55/1.8
Vivitar Series 1 35-85/2.8 [Kiron made] [f/4-f/11 range, too soft wide open]
Vivitar Auto 200/3.5 [Tokina made]
