Ah another Sony RX10 IV convert. I also traded my Canon equipment for this wonderful camera. I too own a Iphone 13 and similarly use it but when I am serious I pick up my Sony. My only regret is the RX's limited low light capabilities but Wallah welcome Topaz DeNoise. Now it is truly perfect. Here are a few examples of my photo shoot at the Revs car museum in Naples FL. The museum is beautifully lit to enhance the cars but terrible for hand hold photography. I am now going through all my images and taking the noise (grain) out of them. If you don't have DeNoise ya gotta try it
I had a similar experience where my iMac could not be upgraded to accept the new software versions so I had to abandon what is not a large paperweight. My alternative was a M2 MacBook Pro and 27" LG UHD monitor that is excellent for what my needs are. So far so Good
