Quantaray Quantaray 135mm f2.8
Minolta MD · 135mm · f/2.8

Overview
The Quantaray 135mm f/2.8 is a third-party portrait telephoto sold under the Quantaray brand, which was a house label of the American retailer Ritz Camera. As noted by community members, Quantaray lenses were re-badged products, most often manufactured by Sigma but sometimes other OEMs, and sold across multiple SLR mounts. Because of this, the exact optical formula behind any given Quantaray 135mm f/2.8 can vary depending on the era and the original manufacturer. The reviews available offer very little history beyond confirming the brand's origins; no unique nickname or cult following is documented. It is best understood as an affordable, generic manual-focus 135mm portrait lens rather than a sought-after collector's piece.
Verdict: The Quantaray 135mm f/2.8 is an inexpensive, re-badged manual-focus portrait telephoto (a Ritz Camera house brand, most likely Sigma-made) with modest but generally positive user ratings. With scant documented information about its rendering, it suits budget-minded shooters looking for an affordable 135mm prime rather than collectors seeking a specific optical signature.
