Sony RX10 Mark IV Delivers 24 fps Shooting with AF Tracking

September 12, 2017

Sony has had two over-riding strategies when it comes to digital camera development: put huge sensors into compact cameras, and make them fast.

The new RX10 Mark IV is a beneficiary of both of these trends. It boasts a 1-inch, 20-megapixel sensor and a burst rate of 24 fps with AF and AE tracking engaged. You can snap up to 249 JPEG images at a clip.

The RX10 series is Sony’s ultra-zoom family and, like its predecessor, the Mark IV features a built-in, image-stabilized 24-600mm f/2.4-4 (equivalent) lens. Image stabilization is good for 4.5 stops of correction, even at 600mm, Sony said.

The Mark IV is packed with 315 phase detect AF points and 25 contrast detect points covering 65 percent of the image area. It’s capable of focusing in as little as .03 seconds.

There are several AF options available on the Mark IV, including an AF limiter, an AF-A mode which automatically selects AF-S or AF-C mode based on shooting conditions, and AF-On which enables you to skip the half-press of the shutter to lock focus.

4K video recording is also available with phase detection AF and full pixel readout. The camera can also record super slow motion at 240, 480, 960 fps frame rates for up to 4 or 7 seconds.

The 3-inch display supports touch focusing and you can select focus points by sliding your finger across the display while looking through the EVF.

Additional features include:

  • native ISO range of 100-12,800 (extendable to 64 and 25,600)
  • top mechanical shutter speed of 1/2000 sec.
  • electronic shutter up to 1/32,000 sec.
  • built-in flash
  • Wi-Fi, NFC and Bluetooth
  • 400 shot battery life

The RX10 Mark IV will retail for $1,700 and ships in October.
