A quick plug for Nikon...

Sadly, I recently lost my Nikon D300 in a burglary, so have replaced it with a D7000. Lighter, quieter and with 16.2 megapixels rather than the 12 of the D3000, it's a very nice body, and the HD movie facility is marvellous for recording young children. It's also possible to shoot at 1600 and (at a pinch) 3200 ISO without too much noise or loss of quality, which is at least one stop (if not two) better than the D300. I do miss the weight of the D300 however, and the feel of a body that fits comfortably into my rather big hands.  But in all other respects I can heartily recommend the D7000.

If you're into Nikon equipment two sites of constant interest are...

Nikon Rumors (for rumours about new Nikon equipment)

and Ken Rockwell's site (although, to be fair, he also covers Canon and Leica) which has reviews of equipment - including old lenses and bodies - and good advice on photography generally.

Find either of them through the search box above.
