42 MP with professional reliability: Alpha 7R III diagnostics

Sony Alpha 7R III (ILCE-7RM3, 2017) is a radically updated, highly detailed Sony flagship. While retaining the 42.4-megapixel BSI CMOS sensor from the Alpha 7R II, Sony has completely redesigned everything else: adding a dual card slot (the most requested by professionals), improving the AF system to 399 phase points with eye detection, increasing the continuous shooting speed to 10 fps and adding 5-axis IBIS. The Alpha 7R III has become the de facto standard for commercial, studio and event photography - and is used by professionals as intensively as possible.

Advertising and catalog photography requires 500–1000 takes per shooting day. An event photographer with 10 fps accumulates mileage rapidly. The 42MP event archive requires a healthy shutter. Check the meter before purchasing this professional tool.

Record resource: 500,000 operations

Sony has set a record shutter life of 500,000 guaranteed operations for the Alpha 7R III - the best indicator in the class of full-frame mirrorless cameras. In practice, this record is confirmed by actual operation. A camera with a mileage of up to 200 thousand is still a “young” professional tool. The electronic shutter does not consume mechanical power during silent shooting.
