Fujinon's New 50mm Lens is Super Fast and Tack Sharp
Fujifilm refreshes its portrait lens for X Series camera.

Fujifilm recently announced the development of its Premista 19-45mm T2.9 cine zoom lens, and now, the company is giving attention to its mirrorless cameras with the release of the Fujinon XF 50mm F1.0 R WR.
You might be thinking, "Doesn't Fujifilm already offer a 50mm R WR lens?" and you would be correct, but that's a F2.0. The selling point here is the extra stop which will give shooters more options when it comes to low-light conditions or dark interiors.
The XF 50mm F1.0 R WR is compatible with all X-Series cameras including the X-T4 and sees a complete redesign. Optically, it's designed from 12 elements in 9 groups and touts one aspherical element and two extra-low dispersion (ED) elements to thwart spherical aberration. Comparing it to the 50mm R WR F2.0, it only has a single ED element, so users should see a difference in image quality right away.

The still lens is capable of covering full-frame sensor and is compatible with X-Series autofocus. When using the X-Pro3 or X-T4, autofocus can be used at -7EV luminance, providing fast and precise autofocus in low-light conditions. The lens also functions with the phase detection autofocus and face/eye AF to track subjects with ease.
Since the lens provides a shallow depth of field, Fujifilm increased the focus throw of the lens to 120° for better accuracy in manual mode or when using focus peaking and focus assist modes. The lens has a weather-resistant design and is sealed in 11 locations to protect it against moisture and dust. Fujfilm says the lens is functional in temperatures down to 14°F (-10°C).
The XF 50mm F1.0 R WR is available now for $1,499 USD.
