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: 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.
Excerpt: The TR Power Pack III does a great job at its intended purpose -- providing fast recycle time, maximum flash power and extended battery life. However, its problems (which lowered my review from 5 to 3) all stem from one thing: the connecting cord. First, the cord is short. I knew this from other reviews, but didn't realize how short it was.
Pros: Consistent Output, Fast Recycling, Powerful Output
Excerpt: looks like this is the one to go for. has all the bells and whistles, fairly good recycle time and provides overall good functionality. Have not had a chance to use the wireless yet, as I could not figure out how to get it setup.
Summary: Worked great and as advertised on my Pentax K10D, *istDl, LX & 645's. Compact, reasonable battery life and excellent output. Looked very promising until the first failure in week 2 when the internal flimsy plastic linkage that retracts the pin locking the flash to the camera hotshoe failed and the flash and camera body became one piece. A second failure occurred just after warranty expiry.
