Released in 2019, the a7R IV was the first full-frame mirrorless camera to reach 61 megapixels — a genuine resolution milestone at the time, and a figure high enough that Sony's later a7R V simply reused the same sensor rather than pushing resolution any further, focusing its own upgrades on autofocus and processing speed instead.

Its pixel-shift multi-shooting mode, combining several sensor-shifted exposures into one composite file, could push resolution to roughly 240 megapixels for genuinely static studio and product subjects — a specialized capability built specifically around the sensor's already-high native resolution rather than a separate feature. It also introduced a new anti-flicker shooting mode and improved weather sealing over the a7R III, real refinements Sony carried forward into subsequent bodies across the full-frame lineup.
Sony also gave the a7R IV a genuinely redesigned grip shape over the a7R III, addressing handling feedback from photographers using larger telephoto lenses with the high-resolution body. A genuine handling improvement photographers specifically noticed.

Frequently Asked Questions
Is the a7R IV's sensor the same as the a7R V's?
Yes, identical 61-megapixel sensor — Sony reused it directly in the a7R V rather than pushing resolution further, putting that generation's real engineering effort into autofocus processing instead. A real engineering-focus shift toward processing over pure resolution.
