PMA 2010 cameras, lenses, other new stuff


I visited PMA 2010 as press today, which got me free wireless, coffee and bagels. I also checked out some new cameras and lenses. Here's a quick run-down of the stops I made and what I saw:


Fisheye Lens vs. Wide-Angle Lens


Fisheye Lenses vs. Wide-Angle Lens

By Scott Gietler














What is a fisheye lens?

A fisheye lens is a special type of ultra-wide angle lens. They are small, ultra-wide, and show a distorted, spherical view of the world, most evident in the curved, outer corners of the photo.


Fisheye lenses happen to work very well underwater for a couple different reasons:

  • They focus very closely
  • There are few straight lines underwater
  • Using a very wide lens allows to get very close to your subjects, giving your photograph more sharpness, and better colors when lit with a strobe.
  • Behind a dome port, fisheye lenses perform better optically than regular wide-angle lenses.
