Compact Tamron SP mirror lens at 350mm for OM mount, super-telephoto reach in a pocket-sized catadioptric design.
The Tamron SP 350mm f/5.6 is a mirror (catadioptric) telephoto lens in Olympus OM mount from Tamron's premium SP line, using mirrors to fold the optical path for a compact 350mm super-telephoto. The SP designation indicates Super Performance build quality above Tamron's standard range.
The mirror design achieves 350mm focal length in a barrel roughly one-third the length of a conventional 350mm lens. The fixed f/5.6 aperture cannot be adjusted — exposure is controlled through shutter speed and ISO only. The characteristic doughnut-shaped bokeh is the mirror lens signature.
Build quality is Tamron SP premium with quality construction and the Adaptall mount system configured for Olympus OM. The compact dimensions make 350mm genuinely portable, and the lens handles well on OM bodies despite the significant reach.
The Tamron SP 350mm f/5.6 Mirror offers compact super-telephoto reach at affordable used prices for OM system photographers. The SP build quality and 350mm capability provide genuine telephoto reach in a package small enough for everyday carrying.
