Fujifilm GF 23mm F4 R LM WR Medium Format Lens (2017)
Product Gallery
Product Overview
Fujifilm GF 23mm F4 R LM WR is an ultra wide-angle prime lens for Fujifilm G-mount. It covers the 44x33 medium format image circle. Introduced by Fujifilm in 2017, it has 15 elements in 12 groups.
For incremental weathers, Fujifilm is kind enough to include weather sealing. On the lens barrel, one can find a physical aperture ring. Those who wish to focus manually can have the best of both worlds (with the usual caveats).
As an ultra wide-angle prime lens that happens to have relatively small maximum aperture, it is best suited for landscape photography. Even though the lens is not stabilized, at this focal range it does not usually matter. In fact, some may be able to get cleaner corners without image stabilization.
