Sony RX10 Mark IV

The RX10 line has already welcomed three popular models, but with a sky-high asking price, this latest iteration must impress.

- 

Almost a doppelgänger of its Mark III forebear on the outside, Sony’s latest RX10 Mark IV builds on the success of that model with an updated BIONZ X processor, a tilting touchscreen, 24fps burst shooting and an AF system that features 315 phase-detect AF points covering around 65 per cent of the frame.

It maintains the 20.1MP one-inch sensor from before, and also carries over the same ZEISS Vario-Sonnar T* 24-600mm (equiv) f2.4-4 optic. Naturally, we also get 4K video recording and an assortment of video-specific controls, such as zebra and Log profiles.

That massive lens is furnished with three lens rings, one each for zoom, focus and aperture, something that will no doubt please traditionalists after a decent level of physical control. There’s only a touch of delay between turning the aperture ring and the camera registering this, although its proximity to the zoom ring means it’s easy to inadvertently knock the latter out of position.
