Thanks for all your replys,
Just been on the back garden with the photon to double check in not being a div....
Took the lense cap off with the built in it on and nothing is in focus not even my car and van 50m away. But with the cap on its sound.
I've had it a few months and had plenty of rabbits and rats with it but might take it back to the shop and see what they say.
I'm pretty sure the spotting range is reduced a lot with the cap on.
Cheers John
