Pentax LX LX Manual - Page 42

Om • FA -1 F A-2 • 40 LX INTERCHANGEABLE VIEWFINDERS The Pentax LX System includes an array of optional interchangeable viewfinders designed to meet almost any photographic situation. Because the LX Integrated Direct Metering system measures light at the film plane, no exposure compensation is required with any of the LX Finder models. Model FA-1 Eye-Level Pentaprism Finder The standard LX viewfinder, the FA-1 combines bright eye-level pentaprism viewing, built-in diopter correction, full data viewfinder display and a built-in "X" hotshoe. Built-in diopter correction is available for the -1.5 to 0 diopter range. Additional correction is possible with the correction lens adaptor and SMC correction lenses. Check your eye doctor for the diopter range best suited for your needs. Model FA-1W Eye-Level Pentaprism Finder The same features as the FA-1 with an extended built-in diopter correction range from -3 to +1 inclusive. Model FA-2 Eye-Level Pentaprism Finder Similar to the FA-1 standard pentaprism viewfinder without the built-in hotshoe. Available in the -1.5 to 0 diopter range as with the FA-1; no wide range model is available. NOTE: The Pentax FA-1, FA-1W and FA-2 Finder models are fully compatible with all Pentax critical focusing accessories.
