Most of my cooking shots are taken using my Canon IXUS 850IS. I'm a huge fan of Canon point-and-shoot digital cameras, and this has the added bonus of a relatively large amount of control over manual settings.
The rest of my shots are taken with the camera in my mobile phone, which is a Sony Ericsson C902. It takes pretty decent shots for a mobile phone.
As times goes on, I hope to remember to carry my proper camera more regularly, and avoid using my phone except in desperate circumstances.
And eventually I'll get myself a digital SLR, and use that for the majority of my photos. Time to start saving!
