Excellent condition rare Tamron SP Adaptall 300mm f2.8. Comes with both Nikon AI mount (currently installed) and a Canon FD mount. Adaptall lenses were renowned for excellent quality glass and their ability to swap out lens mounts.  This one has barely been used and very well cared for. Hardly a mark on it, focus is smooth aperture is snappy, glass is haze and fungus free with hardly any dust.  Comes with original case, hood, 1.4x teleconverter, hard to find Tamron 112mm filter thread multi coated UV protector included, as well as drop in "normal" filter with filter holder. Offered with a 14 day return period to make sure you're happy with it.

Thanks!
