| 1It is unconfirmed whether the Sony a7 III has a low-pass filter. The general (and perhaps surprisng) consensus is that it does not, or if it does, it is a weak horizontal-only AA filter. | ||
| 2Canon only supplied the EOS R1 battery life figures in eco mode, where it is rated for 700 images via the EVF and 1330 in live view. To match the standards of other cameras in this chart, an estimate of 500 shots and 1180 shots are shown here (based on typical LP-E19 battery performance in regular vs eco mode). | ||
| 3The Canon EOS R1’s official dimensions do not include the depth of the protruding viewfinder. To match the typical standards today, 20mm were added to the EOS R3’s depth measurement in this table. | ||
