Yeah, you'd have to brace your arm against something, hold your breath, freeze your body, tap the shutter and wait 2 seconds for the shot to be taken. Then you'd have to take a look at the shot and see if it's blurry or not. And it would be a lot darker and have a lot more noise than your Pixel 2 XL shot.
As a person that is currently still using his 3 year old Droid Turbo 1, I am extremely interested in your impressions of the Pixel 2 XL. Maybe start a separate thread, "Coming from a Droid Turbo" and post a review?
