This weekend I photographed the supermoon from Australia with a Canon 5D Mark II and a 300mm lens
The last time I shot the moon was in the UK with my old Olympus E-510 and a 300mm equivalent lens.
In both cases I did not resize or re-sample the image. Instead I cropped out the sky until I was left with an 800 pixel wide image for the blog. The Canon has 21 mega pixels and the Olympus has 10 mega pixels so the result was a larger image this time. I was surprised just how much extra detail was captured when compared to the old shot.
