Pentax 67 SMC 45mm f4 with case and caps

The SMC Pentax 6x7 45mm f/4 is a wide-angle lens designed for the Pentax 6x7 and 67 medium format systems. With a field of view equivalent to roughly a 22mm lens on 35mm format, it’s ideal for landscape, architecture, and interior photography—where a wide perspective and spatial depth are essential.

Despite its wide angle, the lens delivers remarkably low distortion, making it well-suited for precise compositions. The f/4 maximum aperture provides sufficient light-gathering ability for most situations, while the SMC (Super-Multi-Coating) ensures high contrast, natural colors, and minimal flare.

The 45mm f/4 is valued for its sharp image quality, solid build, and reliable performance. It’s an excellent choice for photographers looking to fully exploit the expansive 6x7 negative format in wide-angle work.

The serial number of this lens is 8590493.
