Web site: AF540FGZ Flash
Key Features: tilt/swivel/zoom reflector, wireless, HSS, rear-curtain sync, manual and thyristor modes.
Reasons to Buy: Good feature set. Most raw power of any hot shoe P-TTL flash.
Notable Drawbacks: Forgets settings on power-save.
The AF540FGZ is Pentax's top-of-the-line model, and has the power to match. It lacks a few of the small fancy features (e.g. automatic flash bracketing) found on many Metz models and doesn't have as much manual control. Additionally, many settings go back to their defaults when the flash turns off, even via automatic power-save mode, which could be quite annoying for someone who often uses manual settings or on-flash exposure compensation. Unlike the AF360FGZ, auto-off can be disabled, making that less painful. It'd also be nice to have a little more solidly-built weather-sealed top-end model (like Canon's Speedlite 580EX II). Despite these gripes, the AF540FGZ is generally quite well regarded.

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.
