Compact Pentax M-series constant f/4 telephoto at 75-150mm, miniaturised SMC zoom at budget pricing.
The Pentax SMC Pentax-M 75-150mm f/4 is a compact constant-aperture telephoto zoom from the M-series in the characteristically miniaturised Pentax form factor. The constant f/4 across 75-150mm provides consistent exposure from portrait through telephoto perspectives.
The M-series compact design keeps the lens remarkably small for a constant-aperture telephoto zoom, maintaining the Pentax portability advantage. The SMC coating provides excellent contrast, and the constant f/4 eliminates exposure shift during zooming.
Build quality is compact Pentax-M with all-metal construction. The K-mount ensures compatibility across the Pentax system, and the constant aperture provides practical advantages for manual exposure film shooting with consistent depth of field.
The SMC Pentax-M 75-150mm f/4 offers compact constant-aperture telephoto at affordable used pricing. The M-series miniaturisation and SMC quality provide a portable quality telephoto zoom in the smallest possible Pentax form.
