Pentax 18-250mm f/3.5-6.3 SMC PENTAX-DA ED AL IF Autofocus APS-C Lens for K-Mount Review

The Pentax 18-250mm f/3.5-6.3 SMC DA is an all-in-one zoom designed for Pentax K-mount APS-C cameras. With a 27-375mm equivalent focal range, it covers wide-angle to telephoto in a single package, making it a convenient option for travel and general shooting when you want to minimize lens swaps. The lens features Extra-low Dispersion (ED) and aspherical elements to help control aberrations across the zoom range, plus an internal focusing mechanism that keeps the barrel length consistent during use.

At 168 dollars for a used copy in excellent condition, this lens sits in budget superzoom territory. It's a practical choice if you already own a Pentax APS-C body and need maximum versatility without carrying multiple lenses. The variable maximum aperture (f/3.5 to f/6.3) is typical for this class, meaning you'll see reduced light-gathering ability and shallower depth of field control at the long end, especially in dim conditions. The 62mm filter thread is standard and affordable. For Pentax shooters prioritizing range and portability over optical refinement, this lens delivers functional flexibility at an accessible price.
