Pentax SMC wide-angle zoom from 24-35mm with constant f/3.5, ultra-wide coverage for landscapes and architecture.
The Pentax SMC 24-35mm f/3.5 is a wide-angle zoom for the Pentax K-mount covering ultra-wide through to standard wide-angle perspectives with a constant f/3.5 aperture. The 24mm starting point provides significantly wider coverage than standard zooms, and the constant aperture simplifies exposure.
The focal range covers from ultra-wide 24mm through to moderate wide-angle 35mm, staying entirely within the wide-angle spectrum. The SMC coating ensures excellent contrast and flare resistance, and the constant f/3.5 maintains consistent brightness and depth of field throughout the zoom range.
Build quality is quality Pentax K-mount with all-metal construction and smooth mechanical operation. The compact dimensions maintain K-mount portability, and the lens provides wide-angle zoom capability that standard zooms starting at 28mm or 35mm cannot match.
The SMC 24-35mm f/3.5 offers specialised wide-angle zoom capability at moderate used prices for K-mount photographers. The 24mm ultra-wide start and constant aperture make it a practical choice for landscape and architectural photographers who need consistently wide coverage.
