Yes, the Wein Safesync is designed to do exactly that:


The extra contacts on the Canon hotshoe are to allow the flash to communicate with the camera, in order for the flash to read camera settings (such as the lens focal length to set the zoom factor) as well as access to the camera's light meter to perform automatic TTL (through the lens) flash metering. To simply fire a flash in time with the camera shutter ...


I would use the hot shoe, especially with panormas - I have had contact issues with PC flash connectors (even the screw lock kind) in the past; the connector isn't really mechanically robust. Besides, a missed release confirmation isn't so bad: you might end up with false negatives (duplicate shots that the system repeated because it didn't get the ...


The extra pins are used for proprietary communication between Canon camera bodies and compatible flashes (primarily Canon, but some third parties have backwards engineered the communication). It includes information about through the lens metering and also the ability to control settings on the flash from the camera body. As far as the flash having to be ...


The EOS 5D Mark III and EOS 7D require a firmware upgrade to be compatible with the GPS Receiver GP-E2, which will be available soon To my understanding you can in fact use the GPS unit separately or on the hotshoe. When you use it separately you have to connect it to the camera via usb. As for holding it close to the camera I recommend that pocket ...


Well, if you want to use any of the flashes you purchase on your camera body as well, then getting receivers that are designed for Sony (originally Minolta) hot shoes is a good idea and that may mean needing a Sony mount. However, one thing to consider is that Sony, for reasons I'm try to understand, put an ISO standard hot shoe on the A99. So... If there's ...


I'm not quite sure exactly what you are looking for. There are only a few main things that I commonly see hot shoes being used for these days: Flash Units Flash Cords Bubble levels Video Lights Microphones GPS Units In the past I have seen them used for a few other things, but this is much less common: Special viewfinder type units Light meters Since ...


The circuit will connect the shoe mount to the center pin to fire. It sounds like up to 6 volts is what Canon asks for, but it can apparently vary a lot depending on the flash. Other pins may contain other signals, but that portion is proprietary in most cases so you'd probably want to use the circuit completion and provide your own low voltage signal. ...


It sounds like your connector is loose and the contacts internally occasionally do not connect. This is common occurrence in many, many consumer electronics surrounding connection points. This is evidenced by when you nudge it one way or the other, it working / not working. Either try to get it repaired or replace it.


For camera menu control, you need to have a flash that has that feature in it. All of the flashes with that feature have all five of the pins on the foot to correspond to Canon's five hotshoe contacts so that the flash can electronically communicate with the camera (however, five pins is no guarantee of menu-command capability--e.g., even Canon's own 580EX ...


I was having the exact same problem but wasn't able to get it working, even after doing a ton of research. I think I have your solution if you're having the same problem that I did; the flash will not fire if you have the LCD screen active, the pulse is not emitted to the flash to trigger it unless it is being viewed through the viewfinder. Hope that ...


Step 0) Make sure you're turning the screw the right way. :) I've inadvertently tightened the flash on the shoe while trying to get it off by not doing this. Chances are good that the spring-loaded locking pin is stuck. You can try using a thin piece of metal between the shoe and the foot, to get it to disengage if it's only partially in the hole. But ...


Modern flash units from recognizable manufacturers rarely use camera-damaging trigger voltages, so you don't need to worry about the 580EX. Once upon a time, the flash trigger transformer's primary voltage (several hundred volts) was directly switched by contacts in the shutter in order to generate the 4000 or so volts the flash tube needs to have in order ...


If you want to use your in-camera AF light, you must disable hotshoe flash monitor pin, but this causes TTL to stop working and flash will trigger at minimun power, just usable in flash M mode.


It may or may not help, but: if I turn the AF assist light off on an SB900, my D300 will use the built-in AF assist light, even with the SB900 attached. If your flash has the option to turn off it's AF assist light, that might do it for you.
