If the alleged pentax ff camera will use the new 42mp bsi sensor from sony with the sensor based phase detect AF, would the transition to mirrorless be easier. Here are the advantages if pentax decides to go mirrorless:
1. Best platform for legacy lenses. If it supports aperture and shutter priority for at least the pentax-a mount.
2. Best platform for 3rd party lenses. Mirrorless camera with access to sigma and tamron lenses. Best platform for samyang and zeiss zk mount, even the zeiss otus and milvus lenses if zeiss decides to manufacture it in k-mount (focus peaking/ stabilized). Manual focusing with the lens aperture wide open like most mirrorless cameras, unlike what we have today in liveview.
3. mirrorless camera with the best ergonomics. Shouldnt be hard for pentax to beat sony in this regard.
4. Mirrorless camera with access to film photography. Film is not yet dead, and i cant afford leica.
4. Better video for Pentax, i hope.
