This flash for PENTAX digital cameras has a weather-resistant design, LED light and is for taking pictures with a guide number of 54 at ISO 100. Thanks to its robust design the flash can be used even in adverse weather conditions - rain and fog, as well as places where it might be splashed with water or in a dusty environment. The body has a built-in LED light, which you'll appreciate when shooting at close range (such as macro), and better illumination of recorded clips.

The user can customize the operation of nine different flash preset functions. It also offers a wide range of firing modes including P-TTL automatic flash mode, in which a preparatory glimpse is detected by the camera's sensor for precise alignment of the main flash. This ensures correct exposure. Flawless synchronization with very short times and wireless P-TTL auto flash.

yet probably the best thing to buy Pentax, Pentax with K3, setovým 18-135 WR lens and flash that can shoot still in the pouring rain.
Waterproof, battery life, LED přisvětlovací - the possibility of video or modulate illumination light when reflected in flash portrait, exposure accuracy, GN nothing
