Sony just announced their next generation of long lens camera in the RX-series, the RX10 Mark IV.

It's uses Sony's latest 20.1MP 1.0-type EXMOR RS CMOS stacked image sensor with BIONZ X image processor and front-end LSI.  It introduces a few firsts for the RX10-lineup, including 315-point phase detect autofocus and a 3.0" 1.44M dot tilting touchscreen LCD on the back.

The RX10 IV features the same excellent 24-600mm equivalent lens as the RX10 III, with a F2.4-4 aperture and 4.5 stops of image stabilization. The lens includes a super ED (extra-low dispersion) glass element and ED aspherical lenses for minimizing chromatic aberrations and a ZEISS T* coating minimizes flare and ghosting.

The combination of the 20.1MP 1.0-inch sensor, BIONZ X image processor and front-end LSI mean the RX10 IV is capable of up to 24 fps continuous shooting with full AF/AE tracking. Like the 315-point phase detect autofocus, this was first found on the RX100 Mark V. The RX10 IV's 0.03s AF response time slightly edges out the RX100 V's 0.05s.

Video goes up to a 4K (3840 x 2160 UHD) resolution and 24/30 frames per second. Slow motion options go up to 960fps at 1080p Full HD. For professional shooters, there's S-Log3/S-Gamut3, Gamma Display Assist, Proxy recording, Time-code as well as a microphone input and headphone output.

The Sony RX10 Mark IV is expected to ship in October with an MSRP of $2,199.99.
