The Pentax LX is a remarkable, professional-use 35mm SLR camera. Introduced in 1980, production of this fine instrument apparently ceased only recently, in the late 1990's (although even now it is still available new).

Rather than duplicating information available elsewhere, these pages largely provide information about some of the nuances of LX operation which I was only able to determine through experimenting with mine, and which may be useful to other LX (or Pentax) users.

• LX metering pattern
• Function of the LX flash contacts
• Sync speed with dedicated flash
• Defeating flash dedication
  (i.e. using flash at your choice of shutter speed)
• TTL flash accuracy with dedication defeated
  (i.e. effect of dedication on TTL sensor pre-flash LED)
