My father, who also does a fair bit of railway photography, is looking for a new camera. He is on a budget of £150-£350 (£400 max). Preferably, the camera will be able to take good quality photos and HD video. My camera knowledge is thin on the ground, so rather than rifling through hundreds and hundreds of pages on the internet looking for something suitable I thought I would ask on here instead. Any help will be very much appreciated.
