Pentax AF100P Flash for Pentax 110 Film Camera

The Pentax AF100P is a dedicated electronic flash unit produced by Pentax, a well-known manufacturer of cameras and camera accessories. The AF100P is designed to be used with Pentax's line of 35mm film SLR cameras, and it may also be compatible with some digital Pentax cameras, depending on the model and flash interface.

Here are some key features and details about the Pentax AF100P flash:

1. Flash Power: The AF100P flash unit provides a decent amount of flash power, which is measured in terms of its guide number (GN). The specific guide number may vary depending on the flash's zoom settings and ISO settings, but it's typically around GN 26 meters (at ISO 100, with a 35mm zoom setting). This means that the flash is capable of providing sufficient illumination for subjects at various distances.

2. Bounce and Swivel: The flash head of the AF100P can be tilted (bounced) and swiveled to allow for more creative control over the lighting. Bouncing the flash off a ceiling or wall can help soften and diffuse the light, reducing harsh shadows and creating a more flattering look for your subjects.

3. Auto and Manual Modes: The AF100P typically features both automatic and manual modes. In automatic mode, the flash will automatically adjust its output based on the camera's metering and the subject's distance. Manual mode allows you to set the flash output manually, giving you greater control over the lighting.

4. TTL (Through-The-Lens) Metering: Many Pentax flashes, including the AF100P, are equipped with TTL metering, which means the flash communicates with the camera's metering system to provide optimal exposure. This feature ensures that the flash output is tailored to the specific lighting conditions and subject distance.

5. Red-Eye Reduction: The flash unit may include a red-eye reduction mode, which involves firing a series of pre-flashes to minimize the appearance of red-eye in your photos.

6. Power Source: The AF100P flash is usually powered by four AA batteries. It's essential to keep spare batteries on hand, especially if you plan to use the flash extensively, as the power source can quickly deplete with frequent use.

7. Compatibility: The Pentax AF100P flash is designed to be compatible with Pentax K-mount cameras and some older Pentax 35mm film SLR cameras that support a dedicated flash interface. The exact compatibility may vary depending on the camera model, so it's a good idea to consult your camera's manual to ensure it works with the AF100P.
