The Blackstone model, which is made of metal and costs $650, is a reasonably priced full-frame lens. The lens has a fast maximum aperture of f/2.4, allowing for shooting indoors, achieving out-of-focus backgrounds, or shooting in low light conditions.

Vignetting is noticeable at wider apertures, and the lens exhibits average flaring and coma. The bokeh, however, is neatly rendered and not distracting.
