Excerpt: I replaced a Sigma 610 with this flash and was surprised at the lack of power. Build quality seems ok, except for the battery door which is flat out lame. The lighting was inconsistent and consequently I'm for a very long editing session from a wedding I shot last weekend. I expected better from Pentax.
Excerpt: Wireless, easy to mount, learning curve for the newbie, she will use it mostly for portraits and family photos at events. She bought a cheap one a month ago and it has been sent back. This is the real deal.
Excerpt: I've used this flash for a couple of years, and today I ordered a Canon 580exII to replace it, for one reason: The plastic hotshoe foot. I've snapped two off of this flash by knocking short light stands over (Its companion 580exII has suffered the same fate multiple times without issue due to the metal foot.) Replacing the hotshoe assembly is $, and after a couple of times it becomes not worth it.
Excerpt: This is one of the few pro-level flash options for Pentax. It has the capability to work well, but has a few annoying attributes. The flash head has a button to unlock it to pivot, but, in reality, the button only locks the flash from going to a negative angle - questionable value. The flash often doesn't quite nail the exposure with P-TTL. Recycling times could be better, too.
