Portable flash for medium format HI I have a medium format mamiya 645 and mainly use it with studio flash or ambient light. HOwever I am wanting to take some photos at a friends wedding and wan to invest in a flashgun. I have no idea about how these work, and would appreciate any help anyone can offer. I had been thinking about the sunpak 383 or the vivitar 283. I am confused as to how exposures are calculated with a flashgun, and would like to know if these models offer an option to alter the power of the light given from the flash. I will probably buy a diffuser or softbox also. All comments appreciated! Thanks

Either of the flash models you mention will work fine. However, I would strongly recommend the Vivitar 285 over the 283. The 285 flash can be zoomed to match the focal length of your lens. They can fired in two configurations - manual, which can be incrementally dialed down from full power to about 1/16th power, and Auto Flash. For Auto, there is a light sensor built into the front of the flash. The sensor reads the flashlight when the flash is fired, and cuts off the flash at the appropriate time. Two things you need to remember when using the Auto Flash - your flash sensor MUST be aimed at the subject with nothing blocking the way, and your camera and flash both have to be manually set to the same aperture. There are some older Sunpak 'potatoe mashers' (like the 522, and a couple of others whose model numbers I can't remember) which have optional remote sensors that will mount in your camera's flashshoe. This way, the sensor is always aiming the way your lens is, and allows you to shoot the flash off-camera with more convenience and accuracy.

One thing I failed to mention. There is a cable available to connect the flash to the module.
