Mu-43 Regular
The pixel pitch of higher sensor formats has finally reached M43 (see: 90D and A7Riv sensors), which might mean that we'll soon get some technology scraps from the big boys.
The A7riv sensor is a lot more interesting as an example, since the 90D's pixels are roughly equivalent in quality to the 20MP M43 sensor.
With the A7riv, you can just take a M43 sized crop out of the middle, and get better image quality than the 16MP M43 sensor. What are the chances that Panasonic/Olympus would use a M43 size version of this sensor? Would you be interested in a camera that has this?
Looking at DXOmark for A7riii (the iv is supposed to maintain parity at the pixel level)
DR: 13.5 stop vs 12.8
Base ISO: 100 vs 200
Advantages:
- Easier 4K processing with less subsampling. The pixels are less noisy, which would compensate for higher noise from less subsampling.
- ISO 100 is more convenient in some shooting situations (e.g. less need for ND, capture wider tonal range in some scenes)
Possible issues are:
- Reduction in megapixel count. Hard to sell (though Nikon pulled this off with no issues with the D500)
- High ISO performance is a regression for Olympus cameras; the FF sensor corresponds to 825 ISO with a M43 crop, which matches Panasonic but is lower than Olympus's 1300
