When I first switched to digital a few years back I had waited for SLR cameras to get to a minimum of 5 megapixels. They hit it and I bought a nice expensive SLR camera, wrapped it in an equally expensive housing and off I went underwater to shoot away. Needless to say, it was barely adequate but it did the job. And technology moved ahead at a blindingly rapid pace. Cameras became much cheaper, more versatile, and hosted far more megapixels than I could have ever imagined.
