Fujifilm has just announced its latest GF lens, the Fujinon GF 100-200mm f/5.6 R LM OIS WR. It’s made for medium-format GFX system. The lens offers 5-stop optical image stabilization. It’s designed particularly with nature and landscape photographers in mind, but I believe portrait photographers could find it useful as well. Let’s dive into specs and see what you can expect from the latest Fujifilm’s telephoto zoom.
