If you buy a camera in a shop, the first accessory they will try to sell you is a UV filter "to protect your lens". What does it actually do, and do you really need one?
What's the best camera for beginners? - someone wants to know this every day. I've avoided naming names until now, because all digital cameras nowadays are great. But a few makes and models keep cropping up as the best-loved in my online courses and in person workshops, so I now feel that I have enough hands-on experience to make some recommendations.
