OM System MC-14
Extends the reach of OM SYSTEM's 40-150mm f/2.8, 300mm f/4, and 100-400mm PRO lenses by 1.4x, transforming the 300mm f/4 into a 420mm f/5.6 while preserving full weather sealing. Its compact design adds negligible bulk and keeps the 150mm minimum focus distance, making it a practical field tool for sudden telephoto needs. This teleconverter is best for Micro Four Thirds wildlife and sports photographers seeking a weather-sealed, cost-effective path to longer focal lengths without carrying additional heavy glass.
