Digital Camera World Verdict

If you’re after an ultra-wide-angle zoom for a medium format camera, there’s not much to choose from. The GF 20-35mm for Fujifilm GFX cameras stands out as a seriously strong option, with an ‘effective’ 16-28mm zoom range in full-frame terms, coupled with a constant f/4 aperture. It’s surprisingly compact and lightweight for a medium format lens but has a robust, weather-sealed build, refined handling, fast and virtually silent autofocus and delivers exquisite image quality. It’s undeniably pricey but you get what you pay for and more besides, making it very good value and a lens to treasure.

The Fujinon GF 20-35mm F4 R WR takes medium format photography into the ultra-wide dimension. It gives the same range of viewing angles as using a 16-28mm zoom on a full-frame camera, taking the much larger image sensor of a medium format camera into account. And it’s not just size that matters. The Fujifilm GFX100 and GFX100 II have a monster megapixel count of 102Mp, demanding the utmost in resolving power from companion Fujinon GF lenses. That can be a tall order for a zoom lens that gives extra-large viewing angles of up to 108 degrees.
