Using The Built-In Flash - Pentax SLR Operating Manual

Using the Built-in Flash

Using the Built-in Flash

Use the following procedures to take a picture in low light or backlit
conditions or when you want to manually use the built-in flash.
The built-in flash is optimum at about 0.7 m to 4 m. Exposure will not be
properly controlled and vignetting may occur when used at a distance
closer than 0.7 m. (This distance varies slightly depending on the lens
being used and set sensitivity. (p.149))
Compatibility of built-in flash and lens
Vignetting (surrounding portions are blackened due to a lack of light)
may occur depending on the lens being used and the capture
conditions. We recommend taking a test shot to confirm this.
