The Canon EF 135mm f/2.8 Softfocus is a short telephoto autofocus prime for Canon's EF mount, designed primarily as a portrait lens. Its distinguishing feature is an adjustable soft-focus control ring that introduces controlled spherical aberration for a diffused rendering, while disengaging for conventional sharp shooting. It fits any Canon EF-mount film or digital SLR body and adapts readily to Canon RF mirrorless cameras.

At recent UK auction, hammer prices for this lens have sat in a narrow £80–£138 band across the last three tracked sales, with £138 repeating as the top result and serving as a working median. That gives a current saleroom value well below its original retail level, and as of 2026 clean, fully functional copies tend to sell for the upper end of that range while examples with cosmetic wear or uncertain softfocus operation price closer to £80. These are UK auction hammer results — wholesale levels rather than dealer retail, so expect trade asking prices to sit higher.
