As a Sony photographer, the new Sony 100-400mm G Master OSS looks like an incredible piece of kit. The constant f/4.5 aperture is an attractive spec, and one that would serve me particularly well as an adventure photographer who loves juxtaposing hikers against towering natural features like mountains and waterfalls.
However, nipping any idea of trading in the predecessor model — the Sony FE 100-400mm f/4.5-5.6 G Master OSS, a lens which I currently own and use regularly — for the new model is the eye-watering price tag of $4,298 / £4,399 / AU$7,399.95.
