No. These are the Takumar/Pentax/Asahi f2.5 135mm lenses:
Super-Takumar 1/2.5 135mm - M42 mount, 58mm filter, around 450 grams
Super-Multi-Coated Takumar 1/2.5 135mm f2.5 - M42 mount, 58mm filter, two slightly different optical formulas, 450-470 grams. One optical formula is like the Super-Takumar and one is like the SMC Pentax.
SMC Pentax 1/2.5 135mm - K mount, 58mm filter, 500 grams, two cosmetically different trim rings
Takumar Bayonet 1:2.5 135mm - K mount, 52mm filter, 395 grams, slide-out hood, multi-colored distance and aperture markings.
The Takumar Bayonet 1:2.5 135mm has a slightly shorter minimum focus distance but nothing anyone would call macro, 4 feet vs. 5 for the rest.
