Hello,
I'm in need of an external flash gun for my Pentax K-x. I need it for party photography, with a bouncer etc. I've narrowed it down to three options.
Having been photographing intensively for two years, I know my way around, however flash photography is one field where I'm relatively novice.
The Sigma EF-530 Super

The Metz 48 AF-1P

and the Dörr/Soligor DAF42/480 Ultra.
I've been comparing the three and they seem equivalent spec-wise except that the Dörr is significantly cheaper.
Any current users who could weigh in? What should I think about?
Maybe if the price is right think about the Promaster 7500EDF.
I had the Pentax AF360 and its plastic foot broke after a few weeks of use in my tripod adapter. Lucky for me Ritz Camera had a 30 day return policy and I could return it.
Understand my thinking... my Kodak P20 ($120) external flash (made in 2005 for Kodak's prosumers) and my Quantaray (from Ritz camera) $30 external flash (I used for macro work on tripods) never broke after a year of use in the same adapter! For sure the Pentax flash foot is weak, this is good because it saves your camera. But not if you don't have it in the camera.
Many manufacturers use metal for the flash foot. At the time (a couple years ago) Nikon used metal and Canon was starting to use more and more metal flash feet. When I saw the Promaster 7500EDF had a metal foot as a feature I looked into it; because of that incident with the Pentax unit. I latter found manufacturers use metal feet for improved durability (really!) but had a weak break point further up the unit or where the foot is attached to help save your camera in a accident. The metal foot as now used by Metz is simply to prevent the chipping and other durability problems the
often occurs with plastic feet.
The Promaster 7500EDF is a big flash. Its not quite as powerful as the Pentax AF560 but is as large. The 7500EDF is more powerful than the Pentax AF360 and larger. The head can tilt in any direction including facing you! Its has dual reflectors that does have its use and is not a novelty. Using bounce flash ofter leaves you at the mercy of the color of the rooms walls and you can have strange results at times. With the small direct reflector it adds just a touch of sparkle in people eyes and some direct light along with primarily reflected light.
The 7500EDF works well all, features just work, including exposure with the Pentax K10D and K20D, no problems. The unit is built very solid (really) its thick plastic gives confidence. I have dropped it 3' onto carpet with no damage. The flash recharge times at less the full power is really fast, instant at power levels less than half. It lacks two features the Pentax units give. One is high speed sycn. But do realize the faster the speed you shoot the less flash power is available with this feature. I was dead set on a Pentax until I realized the high-speed sync would be useless for subjects over say 60' and apertures high enough for daylight. Its good for running kids. Wireless flash, this is handy especially for macro indoors. But I have a PTTL cord for my 7500EDF which gives me 100% reliable communication, since the wireless flash on the Pentax units use very high speed bursts of light to communicate there is range, angle and many other limitations (and some problems). However the units your looking at don't have this as well AFAIK. Also the 7500EDF has strong clicks you can use any flash accessory with it and the head won't fall. Again a fairly powerful, largish, strong, nice unit.
Now price. I got it for $230 (about) I see they have raised the price! At the time it was just a bit more than the AF360 so it was a no brainier for me as nothing else offered a metal foot. If I was going to spend over $300 than the Metz units would be high on my list. Sigma had problem back a couple years ago. And the Pentax units had tons of problems two years ago. The Pentax units where known to get stuck on your camera and have the battery door break; Pentax your over-due for new flash units! The Promaster like all Promaster flashes despite the second tier name is a quality unit IMHO and worthy of consideration if it meets your needs.
