have a great camera (Lumix G3) http://www.panasonic.co.uk/html/en_GB/Products/LUMIX+Digital+Cameras/Overview/LUMIX+G+Micro+System+Cameras/4855154/index.html
and have taken some great photos with it, even in lowlight- BUT..
I came seriously unstuck at last Sunday's One Love festival of Jamaican Music at Wembley Arena. I'm too embarassed to post the pictures I took... they are all blurred.
I have though long and hard about this, and there are, I think, mitigating factors-
1. It was very hot, very crowded, with a lost of dancing jostling, so it was difficult to hold the camera steady.
2. The stage lights varied in intensity, while the Arena itself was mainly dark.
3. The performers on stage were moving a lot! I was about 10 people from the front of the stage.
4. I'd had a few cans of Red Stripe Lol!
5. The camera is relatively new, and I've sort of jumped straight in rather than read the manual..
So all that points to a fine camera in the hands of a poor photographer. I think I've learnt my lesson and need to swot up on lowlight action photography, while trying to hold the camera steady!
I think the next gig will be a more low-key affair, so I can experiment with different settings rather than be desparate to snap at eveything on stage!
