Hello, I am a beginner to serious photography (currently I have Sony compact, previously a good old Olympus OM10). I am on holiday soon on safari, and would appreciate any thoughts as to a suitable beginners camera? Ideally I would prefer a compact, rather than SLR, for size reasons but I would rather get something right for the holiday. The requirements are something simple to use, ideally including a good all-round lens (for fast moving animals and potentially mixed light), and less than £500. I am happy buying second hand, if that keeps the cost down. Thanks.
