This is the most versatile Canon EF-mount version, which is highly adaptable—not just for Canon cameras, but also for any mirrorless camera system, including Sony E, Nikon Z, Fujifilm GFX (Medium Format), Fuji XF, L-Mount Alliance (Leica/Sigma/Panasonic), and Micro Four Thirds with the right adapter.
With this lens, you can even add a shift adapter to make it an expensive tilt-shift lens, allowing some impossible shots for real estate/architecture, etc.
Whether you're shooting landscapes, real estate, interiors, architecture, or astrophotography — elevate your wide-angle shots with this one-of-a-kind gem!
