The Yashica DF-10 or Kyocera J-Tele is a 1988 budget compact camera with two focal lengths: 35 and 55 mm. A switch extends the lens from its retracted 35 mm position while inserting to extra elements to achieve a greater focal length. Unlike the Yashica DF-100 and most competitors in its segment, the DF-10 is a fix-focus camera. The DF-10S adds a self-timer.
