Can Sony or someone help please.  I bought this new Xperia 1 IV to replace my older Xperia 5 as it is supposed to have a superior camera function.  I've tried the Basic, Auto and P settings but the telephoto lens options give very disappointing images.  They lack focus and definition.  They appear little better than taking a photo with the 24mm lens and electronically zooming in.  I'm using ISO 100 to 200 in bright light and with a fairly high shutter speed.  I have a Alpha 7R camera so am familiar with P settings.  Is there another setting I'm not getting correct or might there be a fault with the new phone camera?

Thanks

Dave.
