The Phase One XF 100MP is a medium format camera with extremely high sensor resolution. It is a modular concept comprised of the Phase One XF camera body, which was introduced in the summer of 2015, and the brand-new IQ3 100MP digital back. The body has a 90-degree prism viewfinder and includes a Schneider-Kreuznach 80mm LS f/2.8 lens. As expected, this does not come cheap: the total price for this kit is $48,990 USD, as of this writing, and is the most expensive camera system we’ve ever tested.

The Sony RX1R II is a high-end compact camera with an integral lens that features a full-frame sensor with a very high resolution of 42MP, comparable in some ways to a classic rangefinder camera or the Leica Q system. The original Sony RX1 was one of the first cameras that offered a full-frame sensor in a compact camera and was sold in two versions: as a “standard” that used a low-pass (anti-aliasing) filter and, as the RX1R, one that was built without a low-pass filter.

The Sony A7R II is a mirrorless, compact system camera with a full-frame sensor and extremely high resolution. The A7R II records images with 7952x5304 pixels and while the more than 42MP resolution is not as high as the sensor resolution of the Canon EOS 5DS, it provides images on the same level as digital backs for medium format cameras.

The new PowerShot G5 X is based on the same sensor system as the G7 X. It uses a 1-inch sensor (BSI technology) with 20MP and a professional 3:2 aspect ratio. Compared to the G7 X, the G5 X has a lot of new and additional features, including a high-resolution electronic viewfinder with 2.36 million RGB dots that is based on OLED technology. By default, the viewfinder offers a frame rate of 30 frames per second, being the most efficient power-saving mode.
