DxoMark posted their Sony A6600 sensor review and test results – Sony A6600’s 24.2MP full-frame CMOS sensor achieved an excellent overall DxOMark sensor score of 82 points (just 3 point behind the Sony A6500), with a combination of 23.8 bits color depth, 13.4 EV dynamic range, and 1497 ISO low-light score.

Image quality compared:
It’s interesting to compare the A6600 with the Micro-Four-Thirds Olympus OM-D E-M1 Mark II. With the introduction of the Mark III, the price has fallen significantly, though not quite to the level of the Sony. Still, the E-M1 Mark II’s lower-resolution 20.4MP sensor is the best of its type and comes remarkably close, achieving a very good maximum color depth of 23.7 bits, and has both a wide maximum dynamic range of 12.8 EV and a very strong Sports score of 1312 ISO.
Like the Sony, Canon’s mirrorless M models also adopt an APS-C size sensor, though they’re typically slightly smaller than the Sony sensors by a few millimeters. All three in our database—the M100, the M5, and the M56—perform similarly, though the 24.2MP Canon EOS M5 is arguably the closest direct competitor to the Sony A6600. Dating back to 2016, it’s still in range but lags behind the A6600 sensor slightly in all three categories. Maximum dynamic range and color sensitivity of the M5 is 12.4 EV and 23.4 bits, respectively, while its low-light ISO score is just 0.2 EV behind at ISO 1262.
Conclusion from DxOMark:
Sony continues to stay ahead with its 24MP APS-C Exmor sensor, particularly with regard to low-light performance and high ISO dynamic range, though overall image quality is largely unchanged from earlier models. It has also ceded some ground to rivals’ smaller Four-Thirds sensors (albeit most likely Sony-made); as for APS-C, Canon has trumped Sony in resolution with a new 32.5MP sensor.
Nevertheless, the Sony A6600 is capable of producing superb-quality images, and the inclusion of its Real-Time Tracking Autofocus for both stills and video, along with a larger battery over its predecessor, make it an appealing upgrade over the A6500. With a well-rounded feature set, the Sony A6600 is an attractive camera at a relatively affordable price.
