Official effective megapixelsThe official effective stills pixel count, expressed in megapixels. When a Japanese official table publishes the figure in 万画素 (units of 10,000 pixels), we convert it to megapixels and label that unit conversion computed. 61 MP 60.3 MP 30%
Official maximum continuous shootingThe official maximum continuous-shooting rate in frames per second, including official high-speed electronic or custom modes when the table lists them. Official rates above 120 fps are clamped at the reference best so one limited custom mode does not dominate the ranking. Restrictions printed on the official table appear as extra wording. 5 fps 15 fps 25%
Official native stills ISO maximumThe official standard or native stills ISO range maximum, not extended or video-only figures when the table separates them. Official maxima above ISO 102,400 are clamped at the reference best. This is a published sensitivity ceiling, not a noise test. 32000 100000 25%
Official in-camera stabilizationOfficial in-camera stills stabilization (in-body, lens-shift or optical), recorded as yes or no when the official table states it. Official CIPA stop ratings, when published, are shown as extra details and are not scored.
