Fujifilm XF 70-300mm f/4-5.6 R LM OIS WR.
Compact APS-C super-telephoto with built-in OIS. Equivalent to 105-450mm — the X-system shooter's wildlife and sports kit.

The Verdict.
Gavler Meta-Score
“The X-system's value reach lens: consistently sharp to 300mm, a genuinely useful 5.5-stop OIS, weather sealing, and 1.4x/2x teleconverter support — all at 580g and under $800. The compromises are a plasticky build, a slow f/4-5.6 aperture, and real softness with the 2x TC. Buy it for X-mount wildlife and travel in good light; move up to the 100-400 for demanding action.”

Sharp and Consistent to 300mm
DPReview found sharpness "nice and consistent throughout the zoom range" and strong "all the way out to 300mm" — a 17-element/12-group design (1 aspherical, 2 ED) reaching a 105-450mm full-frame equivalent.
5.5-Stop OIS at 580g
Built-in OIS rated to 5.5 stops let Amateur Photographer get "reliably sharp images at shutter speeds as low as 1/60sec" at 300mm — in a weather-sealed body weighing just 580g.
1.4x and 2x Teleconverter Support
Rare at this price: works with Fuji's XF 1.4x and 2x TCs (retaining phase-detect AF) to reach 900mm-equivalent, though the 2x costs noticeable sharpness.
Technical Specifications
The Scoreboard
Community 88 leads expert 86: owners value the reach-per-dollar, light weight, and effective OIS, while reviewers trim points for the plasticky polycarbonate build, the slow variable aperture, and the sharpness penalty when the 2x teleconverter is fitted.

Global Critique
“Sharpness remains nice and consistent throughout the zoom range. It's very good news that it remains strong all the way out to 300mm, as that's likely where you'll most want it on a telephoto zoom lens.”
“Here I've been impressed by its capabilities; at 300mm, I've been able to get reliably sharp images at shutter speeds as low as 1/60sec.”
“It's also nice and light, tipping the scales at 580g (1.3lb). That's doubtless been achieved in large part thanks to liberal use of plastic in the 70-300mm's design. There's no getting around the fact that it's quite plasticky.”
“With the 2x TC, there's a very noticeable drop in sharpness, while chromatic aberrations are significantly magnified. Color fringing can remain even after corrections with this combination.”
