Paterson InterFit "E" Flash, Flat Panel on Camera Flash.

Got a couple of these with a package of used stuff and was quite impressed. Light is much softer than with a bare bulb and makes a very noticeable difference.

The hot shoe connectors are a great design and enable one or two to be held in each hot shoe mount. I've had some problem with getting a good pc cord connection, but pc cords do tend to go so I'm not sure if it's the connector or the cord.

Will be perfect for trips to the inlaws with some small light stands. With a 550ex in manual mode on my 1Ds, and the built in slaves, I can meter with FEL through the camera too, so no need to bring a light meter. Just need to adjust the flash to subject distance to change the amount of light.

First-this product is best you can get for the money. The other manufacturers products are extremely pricey and unreasonable.
Second-I had a little problem. I didn't know how to work something so I called customer service and they were GREAT, oppesed to some other companies that make you feel stupid for not knowing how to do something.
Thirdly and most important EXCELLENT PICTURES
