I don't know about that. The last version of the Takumar Screwmounts were carried on in the 1st versions of the K Mounts. The first K135/3.5 (52mm filter) is different from the later K135/2.5 (58mm filter). I've never seen a screwmount 135/2.5 Takumar design. There are some sad 135/2.8 bayonet mount 'Takumars', but without SMC coated glass. Regards, Bob S.
