The '''Vivitar 35mm f/2.8 Compatible T System''' lens is a '''[[T mount]]''' preset lens distributed by [[Vivitar|Ponder and Best (later Vivitar)]] in the 1960s. Ponder and Best designated the family to which this lens belongs as the "Compatible T System". With only one exception, the Compatible T System family consisted of prime lenses, including mostly long telephoto lenses. The only non-telephotos were this lens and a [[Vivitar_35mm_f/3.5_Compatible_T_System|35mm f/3.5]] lens. This lens included a screw-on metal lens cap. The lens is marked "Made in Japan". Based on information from Bill Swinyard, the Ponder and Best product manager from 1968-1971, the  manufacturer is believed to be '''Tokyo Optical Equipment Manufacturing''', aka '''Tokyo Koki''', which later became known as [[Tokina|'''Tokina Optical Equipment Co, Ltd.''']]<ref>personal correspondence between Bill Swinyard and Steve Rainwater, 21 Feb, 2012</ref> There is still some doubt and other sources of confirmation of Tokina as the manufacturer are being researched.

The lens can be used on most modern DSLRs with an appropriate T or T2 adapter. Full frame users should be careful that the camera mirror clears the rear element of the lens, which extends quite far out the back of the lens. When set to infinity focus, the rear element can extend beyond the back of the T mount on some mount adapters.
==Variants==
'''Version 1 (early/mid 1960s)''' - The earliest version of the lens had a metal focus ring with alternating flats and longitudinal ridges. It was badged as a '''P&B Vivitar'''. This version is rare.

'''Version 2 (mid 1960s)''' - The second version of the lens retained the metal focus ring with alternating flats and longitudinal ridges but switched to '''Vivitar''' badging, dropping the P&B. This version is rare.

'''Version 3 (late 1960s - mid 1970s)''' - The final version of the lens had a metal focus ring with longitudinal ridges only and a '''Vivitar''' badge (pictured on this page). This is version was distributed for approximately five years and is the version most commonly found today.
