Hoya wide-angle for Pentax K with HMC coating and auto aperture, convenient wide-angle shooting at budget pricing.
The Hoya 28mm f/2.8 HMC Wide-Auto is a wide-angle prime in Pentax K-mount with Hoya's premium multi-coating and automatic aperture coupling. The Wide-Auto designation indicates the lens provides automatic diaphragm operation, stopping down only at the moment of exposure for a bright viewfinder during composition.
This is essentially the same optical design as the standard Hoya HMC 28mm f/2.8 but with the automatic aperture mechanism that provides a more convenient shooting experience. The HMC coating technology brings Hoya's world-leading filter expertise to the lens optics for excellent flare and ghosting resistance.
Build quality matches the standard version with all-metal construction and smooth mechanical operation. The automatic aperture mechanism adds convenience for everyday shooting, and the Pentax K-mount provides full compatibility with the extensive K-mount camera range.
The Wide-Auto version offers the same optical quality as the manual-stop-down variant with added convenience. On the used market, both versions provide affordable wide-angle capability with the genuine advantage of Hoya's HMC multi-coating technology.
