FUJIFILM Fujinon GF 250mm f/4 R LM OIS WR Autofocus Lens for G-Mount, Black {82} with Tripod Collar

Fujifilm GF 250mm f/4: the telephoto standard for GFX shooters

At 250mm on a G-Mount body, you're working with roughly a 198mm equivalent field of view, tight enough for subject isolation, long enough for event and wildlife work where you can't get close. The optical formula runs 16 elements across 10 groups, with one Super ED element and two standard ED elements doing the heavy lifting against chromatic aberration. That Super ED glass specifically addresses the way chromatic fringing shifts with shooting distance, which matters when you're pulling focus across a range of working distances than locked onto a single plane.

The 5-stop OIS (CIPA-rated) is the practical engine behind this lens for handheld telephoto work on a medium format system. Combined with the linear motor autofocus, which is both fast and quiet enough for fieldwork without mechanical noise intrusion, you get a telephoto that doesn't demand a tripod for every frame. A focus limiter and focus preset function round out the control set for shooters who need quick repositioning between targets. The 9-blade aperture produces clean circular out-of-focus rendering at f/4, and the tripod collar ships in the box for when you do mount up. Attach the GF 1.4X TC WR teleconverter and reach extends to 350mm (about 277mm equivalent) with minimal optical penalty.

Who It's For

Wildlife and nature photographers working the GFX system get a lens with real reach, fast-enough AF through the linear motor, and weather sealing rated to -10°C with 18 sealed points across the barrel. Portrait photographers shooting at distance, think editorial or environmental work where compression and subject separation matter, benefit from the f/4 maximum aperture and 9-blade diaphragm on a 44x33mm sensor. Documentary and press shooters gain from the 5-stop OIS for handheld work in available light. Macro-adjacent shooters can also work at the 1.4m minimum focus distance for a 0.22x magnification ratio with telephoto compression.

FAQ

What's the actual field of view on a GFX body?

250mm on medium format (44x33mm) gives you roughly 198mm equivalent in 35mm terms, which is tight telephoto - perfect for subject isolation in wildlife and event work without the weight penalty of a larger format telephoto.

How does the Super ED element work differently from standard ED glass?

The Super ED element specifically corrects chromatic aberration that shifts with focus distance, which matters when you're pulling focus across varying working distances rather than staying locked on one plane. The two standard ED elements handle residual fringing alongside it.

Will 5 stops of OIS actually let me shoot handheld at 250mm?

Paired with the linear motor autofocus on a GFX body, yes. The CIPA-rated 5-stop stabilization gives you reliable handheld work without demanding a tripod for every frame, though you'll still want one for critical shots.

What happens if I attach the 1.4X teleconverter?

Focal length extends to 350mm (277mm equivalent) with minimal optical penalty - both the lens and converter are designed to work together without MTF degradation. You lose one stop at the aperture, so you're working at f/5.6 maximum.

Does the focus preset function actually save time in the field?

Yes. You can store a focus distance in memory and recall it instantly when switching back to a subject at the same distance, which saves AF hunting time when you're repositioning between targets.

Is this lens weather-sealed enough for harsh conditions?

Sealing at 18 points with fluorine coating on the front element handles dust, water, and temperatures down to -10°C. It's built for professional fieldwork, though not submersible.

How does the 9-blade aperture affect bokeh?

Nine blades produce clean, circular out-of-focus rendering at f/4 - no distracting polygonal bokeh shapes in highlights, which matters when you're isolating subjects at this focal length.
