24mm · f/2.5
The Tamron 24mm f/2.5 Adaptall model CW-24 is a compact, lightweight manual-focus lens with good build quality. Optically, it offers decent sharpness in the center but soft corners, especially wide open, with noticeable distortion and chromatic aberration. It handles flare reasonably well but has some vignetting. Best suited for photographers comfortable with manual focus who need a wide-angle lens for general use on a budget.
