Having found it difficult to frame a subject using the EVF of the C700UZ when it is dark, I looked for a solution and found what I think to be ideal in the Petzl Zipka LED torch. This is a compact little torch, with a retractable headband which stows away inside a reel. It fits in a camera bag or even hangs off the strap.
