If this is the lens you've got, then it's 52mm:
Takumar 135mm F2.8 Bayonet Reviews - Non-SMC Pentax Prime Lenses - Pentax Lens Reviews & Lens Database

Otherwise, do a search in our lens database and look at the spec table- the info should be listed there.

Is it a takumar or takumar Bayonette

Note, likely it would be a 58mm in any case because F-stop = focal length / diameter so the front element needs to be 54mm in diameter, and it is unlikely to get the element retention (beauty ring or other) por limit vignetting with a filter, into the last mm before 55mm filter would come into play

If it says Bayonet on the side, 52mm. (All the other 135/2.5s are 58mm.)

Except for a polarizer, if needed, get no filter at all, lack of coatings or poor coatings on older lenses lead to so many reflections that it wil disappoint

Hello,

I called our Used Dept and they confirmed the f/2.5 lens accepts 52mm filters.

The Tiffen 52mm Photo Twin Pack consists of a UV Protection filter and Circular Polarizer.

UV Protection Filters
UVHaze (UV) filters are wise initial investments. They help protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs. If desired they can be left on the lens at all times for protection. Haze filters provide additional benefits of correction for Ultraviolet (UV) light which can register on film and videotape as a bluish cast and can obscure distant details. Ultraviolet filters allow you to correct for the UV effect to varying degrees. Haze-1 filters absorb approximately 71 percent of UV.

Circular Polarizers
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
