Sigma 600mm F8 Mirror [143/144?]	prod ID, test results
prod ID: [143] (source: Sigma USA lens chart), [144] (source: Martin Trautmann) ... Trautmann's list is older than Sigma's chart but the number is higher - thus reference to an older version can be excluded

Probably Missing or Missing Models:
Sigma 28-70mm F3.5-4.5 UC [620] 1990-1995

A Note about Sigma FAP (Focus Aid & Programmable):
There is almost no information about these lenses available online. They were made for AF bajonets, but MF only, at the time of 1985 - 1987 (note: Canon EOS cameras were produced since 1987). These lenses exist for Minolta infact, for other mounts I could not find any samples until now. My conclusion is, that they were not made for other mounts. FAP Lenses available: FAP Zoom Lens II 21-35mm F3.5-4.2 - If produced for Canon it can't be [516] (prod. '84-'87, but for Minolta only) nor [517] (prod. '89-?, AF). FAP Fisheye 16mm f2.8 Filtermatic - Afaik/definitly not produced for Canon EF, but found for Minolta. - The front lens group including the lens hood and part of the corpus is removable in one piece (has an internal lens bayonet) to change filters. Comes with normal, yellow, orange and red filters. FAP Super Wide II 24mm f2.8 - Found for Minolta. These were mentioned in some vintage Sigma FAP prospect (without any mount information again). More possible candidates by guess: Sigma 5.6/400 [169] and 8/600 [144] were produced 1987, but are both mirror lenses, the only other 1987s lens in question so far would be the 35-135 [705].
