I believe the moon photo was taken with my 5MP Nikon 5700 hybrid, they can be had for about £150 or less now. You don't need a big DSLR to take great photos, just a camera with a decent lens - the small compacts cannot produce the same quality of images due to the physical limitations of the small lens area and the way light travels through it, in my opinion anyway.. there will always be a little vignetting or distortion towards the corners. Of course, some compacts come with slightly fatter lenses so they go some way to improving things, but there's no bettering the even fatter lens of a hybrid or SLR!
Where is it? Got a link??
