Puts my pictures to shame

Link is working for me.
Note he has not just used the phone itself but an add-on lens and binculoars in some of them!
As said they look good but if you viewed them any bigger they would look rubbish!
Plus, in all the indoor shots, it is lit extremely well for the TV cameras, giving excellent photography conditions.
Was it this review?

In which case, yes he would have to go that high to get 1/1000th!
