Lomography Petzval 85mm F2.2 lens


  A reproduction of a a lens designed in 1840 by Joseph Petzval - one of the foremost optical physicists of his day. Previous photographic lenses tended to have very small maximum apertures, and this resulted in extremely long exposure times (especially with the low sensitivity of early photographic processes). Petzval overcame this by designing a lens which used four elements in two couplets, and could be made with the then-impressive maximum aperture of f/3.7, allowing exposure times measured in seconds rather than minutes.
  
  It’s the very imperfections of Petzval’s design [compared toy modern lenses] that have inspired the lens’s resurrection. These flaws, including field curvature and vignetting, give a characteristic look to the images it creates that some photographers value highly, and which really can’t be mimicked in post-processing.

The Last Japanese Mermaids 

For nearly two thousand years, Japanese women living in coastal fishing villages made a remarkable livelihood hunting the ocean for oysters and abalone, a sea snail that produces pearls. They are known as Ama. The few women left still make their living by filling their lungs with air and diving for long periods of time deep into the Pacific ocean, with nothing more than a mask and flippers.

In the mid 20th century, Iwase Yoshiyuki returned to the fishing village where he grew up and photographed these women when the unusual profession was still very much alive. After graduating from law school, Yoshiyuki had been given an early Kodak camera and found himself drawn to the ancient tradition of the ama divers in his hometown. His photographs are thought to be the only comprehensive documentation of the near-extinct tradition in existence
