Imported miniature cameras like A and C above, of high quality, have interchangeable lenses and attachments covering the whole photographic field -- if expertly handled. American miniatures are cheaper but only the Perfex 44, B above, approaches the Europeans in quality and flexibility.

For contact prints cameras of the Speed Graphic or Linhof type, D and F below, are widely used by reporters and professional photographers. Made in several sizes, they use film pack, cut film or plates, and can be fitted with lenses of different focal lengths.
