My new to me used Metabones BM1 adapter allows me to mount a Canon EOS lens to a Micro 4/3 Olympus OM D1. First up on the evaluation list is a Sigma 150 f2.8 macro (pictured below). This could be sweet for butterfly photography. It will have more subject distance and softer backgrounds. The kit combination is equal to 300mm on M4/3. Off to the Niagara butterfly conservatory tomorrow.
The combo works.... sweet
