PHOTOBLASTER (1997 - 2000) Similar in some ways to the design of the Biflex of 1948, the PhotoBlaster has two lenses and two shutters so that the flipping of the film -- as in the Biflex -- is not necessary. For a submini camera it's a little on the big size -- about the size of a Leica M3 -- but the PhotoBlaster is designed for kids. Perhaps I should say that it appeals to the kid in all of us!
