Quantaray 28-90mm f/3.5-5.6 Aspherical Autofocus Lens for Pentax K-Mount, Black Review

The Quantaray 28-90mm f/3.5-5.6 is a budget autofocus zoom lens designed for Pentax K-mount cameras. With a versatile 28-90mm range, it covers wide-angle to short telephoto focal lengths, making it a practical all-purpose option for everyday shooting. The aspherical element helps control distortion, and the 55mm filter thread keeps accessory costs reasonable.

At $31, this used lens targets photographers looking for an inexpensive way to extend their Pentax kit without breaking the bank. Quantaray lenses were often rebranded third-party optics sold through retailers like Ritz Camera, so build quality and optical performance tend to be modest but functional. The variable f/3.5-5.6 aperture is typical for consumer zooms of this era, meaning low-light performance will be limited. This lens fits best as a backup zoom or an entry point for hobbyists experimenting with interchangeable lenses on a tight budget.
