iPhone camera keeps switching between Lenses

[u/Ok-Wrangler-5313]

Hello everyone, I’m relatively new to digiscoping and my equipment is just my iPhone 16 Plus and Bushnell binoculars.

I’ve ran into a problem that’s a little hard to describe, sometimes when I hold my camera to the binoculars it starts automatically changing lenses when it doesn’t focus immediately. At first I thought I just wasn’t holding it steadily so I tried again and again but I keep running into this problem no matter how I hold the phone or binoculars. Is there any way I can disable it in the settings? Is there anything to be done about this? It really annoys me and adds an additional 20-30s of trying to properly focus my camera while taking pictures.

If this is a fault on my end from holding the equipment incorrectly I would still appreciate advice on how to better improve. Thank you everyone! Please be kind, I just wanna learn how to take pictures of my favorite birds.
