The Sony Cyber-shot DSC-RX10 IV camera is an excellent companion for any birdwatchers especially travelling birders and despite having its weaknesses, it delivers decent photos in good light conditions. Last June I posted some results and thoughts on the capability of this camera and now I add some more below.
The Sony RX10 IV is the first compact camera using High-density Tracking AF Technology which activates AF points only around the subject for higher focusing accuracy and consistency. A stunning 65% of the image area of the sensor is covered by autofocus points. It has 315 points Phase-detection AF coverage and 25 points Contrast-detection AF coverage.
A series of photos above shows the tracking perfection of the Sony RX10 IV camera. The Greylag Goose took off from the lake for the feeding grounds just in front of me. The continuous autofocus locked on the goose and kept the focus on even if it was flying behind the trees. This is one of the impressive features of the Sony cameras.
ISO sensitivity and sharpness
In low lights at high ISO settings, images are losing quite a bit of detail and sharpness but up to ISO 400, it creates acceptable images (e.g. Pied Avocet or Audouin’s Gull images above). In perfect lights at ISO 100, the outcome is a crisp and sharp image (see the Black-headed Gull below).
The powerful BIONZ X image processing engine (same as in the Sony a9!) makes ‘High’ Continuous shooting with accurate tracking possible at 24 frames per second (RAW) and at 249 fps if fine JPEGs is selected. Amazingly, most of the photos in any burst are keepers unless I make some mistakes.
Bokeh and reach
The Sony RX10 IV camera sports a stunning 24-600mm equivalent ED lens with 2.4-4.0 aperture and optical stabilisation. The 600mm alone is an ideal focal length for bird photography but the 20.1 megapixel allows plenty of cropping possibilities if the 600mm is not quite enough.
The bokeh is wonderfully creamy if the background is far enough from the subject. I took some pleasant looking shots to show the bokeh performance of the Sony RX10 IV.
All in all this camera is a superb tool for documenting wildlife and in some cases, it can be more than that. In the social media era, 99% of the images are published in postcard-sized digital format for what purposes, the Sony RX10 mark IV bridge camera can produce wonderful images. I might test how professional prints would look like.
