In reply to MeMeMe:
No need to spend much to get perfectly ok results, especially for a youngster. Looking at makes and models it is a minefield of information to sift through and many of the functions irrelevant, at this stage.
My first camera about 3 years ago was a Bushnell, about £200, sent 2 back as faulty and current one never been right (now drains batteries down fast). Have used cheap ones at about £70 supplied by wildlife trust - absolutely fine and currently a Browning (a more expensive model) from them, also very good and simple to operate.
You pay more for slightly faster shutter speeds, image quality etc. none of which a child needs. Sometimes in Lidl/Aldi and believe these work well, I would look for a cheaper camera, certainly no more than £70 and possibly much less. You will have plenty of fun with it, last couple of nights I've had a polecat in the garden.
