Leica has announced the Summicron-M 66 F2, which it says is a “reinterpretation” of one of the rarest M-mount lenses ever made: the Elcan 66mm F2, which was specially designed for the US Navy’s use in “covert reconnaissance photography.”

According to Leica’s press release, there were only around 200 copies of the original lens, designed by Dr Walter Mandler of Ernst Leitz Canada in the late 1960s, ever made. Its spy-centered origins also explain the odd focal length; it was designed to balance providing maximum resolution and contrast, without being too big. It’s not hard to imagine why the US Navy and its allies would want that in the midst of the Cold War.

The new lens contains several references to its lineage. Leica says the aperture ring turns in the opposite direction from a typical M-lens – you twist it left to stop down, instead of right – and the distance scale is military-spec. It will also be a limited edition; the company is producing 660 of them, which will have their serial number engraved on the front ring. The first lens, 001, will be auctioned.

Optically, the lens has 6 elements in 5 groups, and can focus on subjects as close as 1m (3′ 3″) away. It has a 9-bladed aperture. Leica says that, at F2, it will have “distinctive rendering” with “soft bokeh and high contrast,” while providing “maximum resolution” when stopped down. You can see some samples taken by Mike Chudley and provided by Leica below, though it’s hard to critically examine a lens’s performance based on JPEGs that have gone through an unknown editing process. Thankfully, Leica has also provided MTF charts.

The lens weighs 456g (16.1oz), and is around 60mm (2.4″) long. It has a 49mm filter thread and, unlike some other premium Leica lenses, has a screw-on hood, rather than an integrated one.

This isn’t the first reinterpretation of the lens that we’ve seen. Leica’s movie-focused sister company, Leitz Cine, sells the Hugo 66mm T2.1, which is also based on the Elcan. However, that lens is designed for PL and L mount, is much larger and has geared focus and aperture rings designed to make life easier on a movie set.

Leica says the Summicron-M 66 F2 will be available starting September 3 for $10,900. While that’s a hefty sum for an F2 lens, even by Leica standards, it’s a pittance for what you’d pay for one of the originals, assuming you were even able to find one (which is apparently no small task). One went up for auction in 2020, with a starting price of €40,000, though it ended up going unsold. Similarly, every listing of the cine version of the lens that I found had a “Contact Us” button instead of a price, essentially saying that if you have to ask, you can’t afford it.

DJI has announced the Osmo 360 II, its second-generation 360-degree action camera. The latest version is an iterative successor rather than a redesign, building on the original model’s dual square-sensor design and 8K panoramic capture, without substantially changing the camera’s core hardware or shooting concept.

One of the most consequential changes is the move to swappable lenses, rather than the fixed ones used by the original Osmo 360. Following in the footsteps of Insta360, DJI now sells a replacement kit for $30, which is substantially more affordable than having to replace the entire camera if you accidentally scratch or crack a protruding lens.

The camera uses two Type 1/1.1 square sensors (one for each lens) with 2.4 μm pixels, matching the sensor specifications of the original Osmo 360. The company says each of its sensors features “an imaging area equivalent to that of a 1-inch CMOS sensor with a 4:3 aspect ratio,” or 123mm² each.

DJI claims 14.5 stops of dynamic range from the camera, which is one additional stop compared to the previous model. As with most dynamic range claims, though, we’d take that number with a grain of salt, and DJI hasn’t specified where that extra stop is coming from. There’s every chance it’s mainly due to noise reduction, although DJI did somewhat quietly switch to a LOFIC sensor in its Osmo Pocket 4P to improve dynamic range.

The camera is capable of up to 8K/60 video, up from the original version’s 8K/50. Slow motion video also gets an increase, with up to 4K/240 possible, compared to a max of 4K/100 previously. Panoramic photo resolution remains at 120MP, though it gets the benefit of HDR this time around. DJI also added a ‘Spotlight Follow’ mode that promises to track your subject, keeping them in the center of the frame, with footage up to 4K/30 possible in this mode. 

DJI has also updated how users connect the camera to its Mimo app. It now supports the ability to tap to connect using NFC. The Osmo 360 II keeps the same 105GB of onboard storage and is waterproof to 10m (33′) without a case.

The DJI Osmo 360 II will be available for purchase outside of Asia starting on September 15. As expected, it will not be officially available in the US. In most EU countries, the new camera will cost 589 EUR.
