Overview

The Minolta Celtic 135mm f/2.8 MC is an affordable portrait lens with good optical performance. It is sharp in the center wide open and becomes tack sharp across the frame by f/5.6, with smooth bokeh and decent flare control, though vignetting is noticeable at f/2.8. Build quality is a compromise: the focus ring has slippery rubber that may degrade, but it includes a built-in hood and smooth aperture stops. It suits budget-conscious photographers seeking a fast 135mm lens, especially for portraits, despite being less respected than the Rokkor line.
