Overview

The Carl Zeiss Jena Sonnar 300mm f/4 is a large, heavy medium-format lens (4.5 lbs) with all-metal construction and smooth, firm controls. Optically, it delivers outstanding Zeiss quality, especially in the multicoated version, with an image circle that covers Fuji GFX sensors. Weaknesses include its bulk and weight, making it a beast to handle. It suits photographers comfortable with vintage manual lenses on modern digital cameras, seeking classic rendering and build.
