"Auto" setting doesn't work??
I didn't expect a lot from a unit at this price, but this flash is too HOT!! The manual setting is useless for close-up, and the auto setting doesn't seem to make a bit of difference. But, like I said, at this proce, I can us some ND filters.

Piece of junk
This is a complete waste of money since it's a piece of junk. First of all there were broken pieces of plastic in the hotshoe unit/battery compartment that holds the front piece in place and second of all it's all cheap foreign crap. I should have known it was too good to be true for under a c-note for a ring flash unit for my digital camera. Buyer beware! It fires on it's own without depressing the shutter button and it's really cheaply made...

Blew out on third flash.
Everything is cheap about this product. The circuit board fried on the third shot. Warranty non-exsistant, since you have to pay to ship both ways. There was no way I was going to sink more cash into this. That surge when it blew could have taken out my camera and lens. Bite the bullet and go with a real product, or work around it.

Ok product, not for the professional though!
We purchased this product to reduce shadows and glare on items being photographed with close up macro photography for sale at online auctions. It works fairly well, but will need some help from you to be worth it.

The flash is too "hot" at its stock settings. You'll need to adjust your camera to compensate for the overexposure or try to fix it in a photo editing program. The settings are not adjustable on the flash.

The cable from battery pack to flash is short and has too much tension. If you try to use autofocus, it pulls the lens out of focus causing the camera to constantly attempt to readjust. If you then try manual focus, the tension is enough to pull it out of focus if using a sensitive lens. I've tried stretching the cord out, but it hasn't helped much. The construction is also almost entirely thin plastic, from the foot and battery pack to the flash. I'd be very careful not to knock the battery pack against anything too hard or you'll be out a flash.

works even better than expected
This ring flash is wonderful. First thing, it really is a ring flash, not a ring light. That means vastly more light, albeit in a similarly shorter period. It is much more powerful than I thought it would be. Even at 1/250 and f/16, I get a great close-up exposure.

For over a year, I used a Canon S1 IS (Image Stabilization) digital camera. My new Nikon D80 camera is wonderful but Nikon locates their image stabilization not in the camera, but in their VR (Vibration Reduction) lenses. I need extra depth of field so I have to use higher-numbered (smaller-diameter iris) f-stops. That means long exposures. Handheld photos have too much shake with the long exposures. Since I haven't saved enough pennies (and it takes lots and lots of them) to buy a VR lens, my close-up photos are fuzzy unless I put them on a tripod. Tripod is synonymous with heavy, bulky, clunky, cumbersome, and loathed.

More light is a solution but my D80's integral flash casts unwanted deep shadows. The Bower SFDRF Digital MACRO Ring Light Flash doesn't cast those shadows and gives me so much light I can take 1/250th of a second exposures at f/16. That means I can handhold my camera in my shaky paws and take spontaneous sharp close-up photos.

Pentax Cameras History

PENTAX Corporation (before 2000 known as Asahi Optical Joint Stock Co.) was founded in 1919.

asahiflex In 1952 they manufactured first Japanese 35mm SLR camera with a cloth curtain focal plain shutter and shutter speeds range from 1/20 to 1/500 sec. It was called Asahiflex I. But even more revolutionary was their Asahiflex II (1954), having has the world's first instant return mirror system. Before that a photographer had to manually bring down mirror after having taken a picture. This system made rapid shooting possible with a SLR.

In 1957 Asahi Optical Joint Stock Co. carried out another coup - they used of a pentaprism in the viewfinder of the Asahi Pentax SLR. The pentaprism made eye-level viewing possible and provided correct images. It was also the first time that the name Pentax was used on a camera. The very name, as you might have guessed, is derived from “PENTAprism reflex.”

Fancy that Pentax were so popular & successful with their cameras that in More About Pentax Cameras
