Overview

The Carenar 28mm f/3.5 is a compact, classic wide-angle lens with high resolution and low to moderate contrast, typical of early Canon RF designs. Its main weakness is soft corners at wider apertures, which sharpen up when stopped down. Build quality is solid, though many examples require a CLA due to age. It suits photographers who appreciate vintage rendering and don't mind manual operation, particularly those seeking a 28mm option for Leica Thread Mount cameras.
