The Pentax AF540FGZ II Flash

Complete your durable, rugged All Weather camera setup with the P-TTL capable AF540FGZ II Flash from Pentax which features 28 seals, including the hot shoe, that enable a reliable weather-resistant digital imaging system. This unit has a guide number of 177' at ISO 100 and 85mm along with a 35mm equivalent zoom range of 24-85mm, though the auto zoom function is compatible with smaller format Q-series mirrorless cameras, APS-C DSLRs, and medium format 645-series digital cameras. Also, with the use of a built-in diffusion panel the coverage can be extended to 20mm. Another benefit of this flash is tilt from -10 to 90° and rotation 135° to the left and 180° to the right for complete bounce functionality.

The AF540FGZ II has wireless master and slave TTL capabilities with access to 4 channels. It utilizes an optical pulse to transmit information and trigger flash units up to 13.1' away. Also, this unit can be set as a master, control, or slave unit and has access to a contrast control sync setting that enables the adjustment of the output of multiple flashes from a single unit.

An added feature for this flash is a constant LED light with 5 output settings for use during video, as an AF assist light, or as simply another light for your subject. Other settings include a multi-flash mode for stroboscopic photography as well as slow, high-speed, first and second curtain sync. Additionally, the AF540FGZ II runs on 4 AA batteries with a recycle time of 2.6-26.2 seconds and it comes with a case and stand.

Are we out of stock?

If you don't see exactly what you're looking for and that makes you sad, please give us a shout. We might have good news for you. Here's a link to our contact form.

We offer a 3-day inspection period on all sales, during which time you may return the item for a refund of the purchase price, not including shipping.

On this item, we include a LensAuthority 90-day limited warranty. This warranty covers damage that arises from normal use of the item. It does NOT cover accidental or intentional damage. More details are available in our FAQ section.

In addition to the standard 90-day warranty, you may have the option to purchase an extended warranty. If we're able to offer an extended warranty on this item, you'll see a checkbox to add that warranty - see the area just above the "Add to Cart" button.

If you select the extended warranty, you'll get additional protection from Consumer Priority Service ("CPS"). The CPS warranty will take effect after our 90-day warranty ends. However, the CPS warranty term would begin on the date of purchase. For example, if you buy an item with a 2-year extended warranty today, your coverage would end two years from today.
