I got a Sony DCR-DVD201E camcorder for Christmas. Being a novice I would like a wide angle lense but have no idea what I`m looking for. What thread size do I need? Do I need an adapter for some of them? I`m thinking sub 100 GBP sterling. What do you recommend. I also need a reasonable microphone and would welcome your suggestions but keep it sub 100 GBP also please.
