Sony A7 III Review

March 26, 2018 | Mark Goldstein |

Sony A7 III Image Quality

All of the sample images in this review were taken using the 24 megapixel Extra Fine JPEG setting, which gives an average image size of around 12Mb.

The Sony A7 III produced images of outstanding quality during the review period. The A7 III has an extensive and very usable ISO range of 50-204800. ISO 50-6400 is essentially noise-free, while ISO 12800 and 25600 produce more than acceptable results, and even ISO 102400 is OK for emergency use, although we'd hesitate to use the fastest setting of ISO 204800. The RAW samples illustrate just how much processing the camera does by default, though, as they're noisier at the higher ISO values than their JPEG counterparts, with fewer unwanted colour artifacts.

The effective Dynamic Range Optimizer function extracts more detail from the shadow and highlight areas in an image, without introducing any unwanted noise or other artifacts, while The High Dynamic Range mode combines two shots taken at different exposures to produce one image with greater dynamic range than a single image would produce. It only works for JPEGs and for still subjects, but does produce some very effective results.

The various Picture Effects quickly produce special looks that would otherwise require you to spend a lot of time in the digital darkroom, while the Creative Styles provide a quick and easy way to tweak the camera's JPEG images. The night photograph was excellent, with the maximum shutter speed of 30 seconds and the Bulb mode offering lots of scope for creative night photography.

Night

The Sony A7 III's maximum shutter speed is 30 seconds and there's also a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 100.

Image Stabilisation

The Sony A7 III has an in-body 5-axis image stabilization system. Using the FE 55mm f/1.8 lens, we were able to obtain sharp results shooting handheld down to about 1/8th second, 4 stops below the "recommended" shutter speed of 1/50th second.
