I found a telephoto zoom lens in Canon FD mount that looks promising: the Sigma High Speed Zoom 80-200mm f/3.5-4. It's a variable aperture zoom lens, but the variation is only a half stop difference.

The physical appearance of the lens was in mint, like new, unopened, unused condition. The design is sophisticated and feels like a piece of artwork in your hands. I guess alot of the old Sigma lenses I've handled were like that.




"Perfect!" one might think...

However, one of the middle glass had a stubborn cloudy film covering the surface which was easily removed with toothpaste. The front group of glass however, had 'balsam separation'. It is possible to fix this through extreme heating to melt the balsam, separate the glass, clean it, then replace the balsam.

It's not impossible to fix this, but I would have to find a source for the Canada Balsam and wait over a month for the arrival. I guess it's just best to sell this lens as a paperweight...

The result of shooting in its present condition was cloudy images wide open, but noticeably sharp. Contrast improves alot by f/8 and everything's really in crisp focus by f/22.

The Sigma 80-200mm f/3.5-4 was launched in 1978. This lens may be a variable aperture lens but in my book, it sure beats any zoom lenses that range from f/4-5.6, doesn't it?

The lens only extends a little when zooming/focusing. Lenses made around that era still never had 'macro mode' that spoil us nowadays, and the common Minimum Focusing Distance for telephoto zooms of this range is 7 or 8 feet. Taking this into context, this Sigma lens has a MFD of only 5 feet, and that tells us it's a close focusing lens.
