Overview

The RE Auto-Topcor 135mm f/3.5 is praised for exceptional build quality, with a precision aperture ring and smooth focusing. Optically, it delivers sharp images at medium distances, though infinity focus may be limited by adapter compatibility. Its two-stage collapsible hood is notably effective. The modified EXA mount can cause mounting issues on Canon bodies but works with mirrorless adapters. It suits users who value craftsmanship and are willing to adapt for mirrorless systems.
