This isn't a flash, hopefully obviously. It's the Pentax-compatibility module used with the 5750DX or 5250DX. If you get one of those flashes, you'll need this. This may be an appealing option for people with multiple camera systems: you could share the same flash between Pentax and Canon, Nikon, Sony, or Olympus.

Including an Amazon link on this page is the easiest way to display the current prices, without having to keep track of it manually or write a more-complicated tracking script. And as a bonus, there's a picture of the flash. Obviously, the ad is also an affiliate link. As with all advertising on this site, I hope it's not too obnoxious.
