Sony's 61MP RX1R III fixed-lens compact camera is finally here after a ten-year wait

Sony just surprised the photography world by unveiling the RX1R III, a fixed-lens 35mm full-frame compact camera. Coming nearly ten years after the RX1R II, it has a 61MP Exmor R sensor along with Sony's latest image processing technology that promises low noise and high dynamic range. 

Apart from all the new tech, the RX1R III is smaller and more streamlined than before and considerably lighter at 17 ounces than its main competition, Leica's Q3 and the Fujifilm GFX100RF. With that, it's designed to be a "carrying around" camera for street photographers, serious amateurs and others. 

That small size is due in part to the Zeiss Sonnar T 35mm f2 lens that sits partly inside the body. While more compact than before, it has the same optics as the last model and offers high levels of sharpness and color rendering, according to Sony. It comes with a macro ring that enables users to get as close as 20cm to subjects and feature's Sony's new "Step Crop Shooting" function that allows 35mm, 50mm and 70mm focal lengths by cropping into the sensor, just like the GFX100RF can do with a similar button. 

It has up to 15 stops of dynamic range thanks to the high-res sensor and image processing engine. It also features an anti-reflection coating and no optical low-pass filter to boost image quality, though that can cause some moire and other artifacts. Shooting speeds aren't quick at just 5 fps, though it's obviously not designed to shoot sports.

The EVF is middling with 2.36 million dots and 0.7x magnification, though the rear panel offers a decent 2 million dots of resolution. However, unlike the one on the previous model that tilted out and up, it's fixed in order to save weight and size. It also lacks any in-body or optical stabilization, relying solely on electronic stablization. 

With Sony's latest Bionz XR and AI processors, it promises accurate tracking of "subjects, human bodies, heads and the position of eyes," Sony said, even if their faces aren't visible. It uses 693 phase-detection AF points covering around 78 percent of the image, just like Sony's A7R V. 

It's not nearly as powerful as the A7R V for video, but can still handle 4K 30 fps video with 10-bit 4:2:2 color sampling, along with 1080p video at up to 120 fps. No log mode is available, but you do get the log-like S-Cinetone that boosts dynamic range a bit. Other features include a single SDXC UHS II slot, a mic input (but not headphone jack), a microHDMI port and a USB-C input. 

As you might expect, the RX1R II is not cheap. It'll go on pre-order soon for $5,100, with shipping set to start on July 31st. Sony is also offering a handful of accessories (also expensive), including the $300 (!) thumb grip, $250 body case and $200 lens hood (!!).
