Fujifilm’s new nifty 50 f/1 lens can autofocus in near darkness

Fujifilm just unveiled its brightest aperture lens yet — and unlike most ultra-bright lenses, it doesn’t ditch the autofocus. Announced on Thursday, September 3, the Fujifilm Fujinon XF50 f/1.0 R WR is the first f/1.0 mirrorless lens with autofocus.

Despite the bright aperture, Fujifilm didn’t eliminate the autofocus system. The company says that the lens even allows the X-T4 and X-Pro3 to focus as low as -7EV, near-darkness conditions that are a full stop better than pairing those same bodies with a different lens. The lens works with the camera’s on-sensor Phase Detection system, including face and eye AF.

But, nailing the focus on a lens with such shallow depth of field, when shot wide open, will likely be a challenge. Fujifilm designed the lens with a 120-degree focus ring that, in manual focus mode, the company says is more accurate than any existing XF lens. The lens, Fujifilm says, is also designed to minimize focus shift.

“We’re really excited about the XF50mmF1.0 R WR,” Victor Ha, Fujifilm’s electronics division senior director of marketing and product management, said in the announcement. “Not only is it the fastest interchangeable lens Fujifilm has ever produced, but it’s also an incredible tool for visual storytellers to use in telling their stories because its autofocus can achieve critical focus at very shallow depth of fields.” 

The lens is built from 12 elements in nine groups. An aspherical element and two extra-low dispersion elements are included to help minimize spherical aberration. Weather sealing in 11 locations helps keep out dust and moisture, while it is rated for shooting down to 14 degrees. 

Despite the high-end construction, the Fujinon XF50 f/1.0 R WR weighs 1.86 pounds and measures just over four inches long. Fujifilm had originally teased the development of a 33mm f/1.0 lens, but in a later announcement said that the lens would be too heavy, promising a 50mm instead.

While the lens is the first f/1 autofocus for mirrorless, it’s not the brightest glass out there. Nikon’s Noct lens for full-frame cameras is a f/.95 lens and Leica offers the Noctilux series at f/.95, but both lack an autofocus motor. The fast f/1.2 aperture is more common, and f/1.8 is even easier to access still.

Unsurprisingly, the f/1.0 lens will come at a price — but at one that’s less than options like the Noct and Noctilux. The Fujinon XF50mm f/1.0 R WR lens is expected to retail at about $1,500, with availability sometime in the fall of 2020.

Ricoh shoots for the stars with new high-end Star series lens line
Ricoh Pentax Star series lenses

Coming in 2018, Ricoh will launch the first two lenses in the company’s new Star series, targeting enthusiast and professional photographers looking to squeeze out the most resolution from their Pentax DSLRs. Final specifications and pricing have yet to be announced, but Ricoh has stated that the Star series will offer the highest possible performance of all Pentax K-Mount lenses, so we don’t expect they will come cheap.

What we do know is that Ricoh Star series lenses will be produced for both full-frame and APS-C bodies. The first two models are the full-frame Pentax-D FA 50mm F1.4 SDM AW and the Pentax-DA 11-18mm F2.8 for crop sensor cameras (lens names have not yet been finalized and may change). Beyond offering improved sharpness, the lenses will also be constructed with “exceptional toughness and outstanding operability,” according to the press release, keeping true to Pentax’s reputation of building durable imaging products for use in all manner of conditions.

Sony’s new FE 12-24mm F4 is its widest full-frame E-Mount lens ever
sony 16 35mm 12 24mm announced 35 gmaster 24

Sony on Wednesday unveiled two new wide-angle zooms for its full-frame E-Mount mirrorless cameras. Both are decidedly high-end optics, but the $2,200 FE 16-35mm F2.8 G Master takes the top spot, while the $1,700 FE 12-24mm F4 G offers the widest-ever perspective on a Sony full-frame mirrorless body — and a slightly more affordable option. These lenses help round out the FE ecosystem, which until now had lacked a professional wide-angle option.

As the first wide-angle G Master lens, the FE 16-35mm F2.8 joins the 24-70mm F2.8 GM and 70-200mm F2.8 GM to round out the lineup of high quality, fast-aperture zooms. Sony has crammed as much optical and electronic tech into it as they could. It contains five aspherical elements, including the largest Extreme Aspherical (XA) front element that Sony has ever produced. It also has two Extra-low Dispersion (ED) elements, Nano AR coating, and an 11-blade aperture for circular bokeh at any f-stop.
