Yes, the Wein Safesync is designed to do exactly that: http://www.weinproducts.com/safesyncs.htm

In some cases, using a hotshoe cover prevents the internal flash from popping up. Many Canon models had (currently have? I don't know) a microswitch in the hotshoe rails, that sensed the presence of a flash. Of course, the hotshoe cover's geometry looks just like the foot of a flash, so the camera thought an external flash was attached, and would not pop up ...

I've never used a hot shoe cover. I've shot outdoors with various cameras (Mostly Canon since the early 1990s) for several decades and never had an issue with a hot shoe that could be remotely related to not using a hot shoe cover. In fact, the only hot shoe related issue I can remember ever having was due to one of the contact springs on an outer rail ...

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 ...

Yes, the hot shoe is the same across all EOS bodies - and if all you care about is manual control (no eTTL, HSS and the like) it's actually standard across the industry, with the only notable exceptions being some Sony bodies and the Nikon 1 system which use a proprietary hot shoe.

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 hotshoe cover is to protect the contacts in the hotshoe from any dirt or water exposure or damage that might be caused during use of the camera. I've lost the hotshoe covers for all my cameras the first time I've used the flash, and despite using my camera out in the great outdoors a lot (around a lot of children), I've never felt like they added much ...

On any iso-compatible flash or camera hotshoe, the sync signal--the one that fires the flash in sync with the shutter opening on the camera--is communicated by the pin in the center of the "square" of the hotshoe/foot. So, to fire a flash correctly, you can use any ISO-compatible flash. It just has to have that square layout, use the rails as ground, and ...

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. ...


2

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.

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 helps!...

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 ...

The large center pin is the main thing (along with the ground connections at the edges) on a standard hot shoe. The smaller pins are for proprietary communication between a specific camera brand and flashes compatible with that brand's automatic flash protocol. If you are creating a self made flash you only need to be concerned with the center pin and ...

The main signal that you want to know about is at the big contact in the middle, labeled X-Sync in your second image. To trigger the flash, the camera shorts this contact to ground (the sides of the hot shoe). It's not surprising that you didn't see this with a meter -- I believe the flash supplies the voltage, so with no flash connected there's no voltage ...

Assuming your body isn't weather-sealed, the hotshoe contacts don't need much protection as the rest of the camera would suffer before the contacts, which are easily cleaned. I sometimes use a hotshoe cover with a built-in spirit level (neither of my cameras has a level display in the viewfinder). It's handy especially on a tripod, but keeps getting ...

Looking at images of the Olympus Trip 35, the hotshoe is a standard ISO one, with the single sync contact, so any ISO-compatible hotshoe flash (i.e., pretty much all of them) should fire correctly in sync. But they won't do anything else. You'll have to use the flash in Manual mode, and manually dial in the power level you want, or hope you find a flash that ...

To trigger a flash with a basic "fire" only command, the camera does not output any voltage at all. It just closes the circuit between the ground (G in you top photo) and the X-sync pin (D in your top photo). This allows voltage supplied by the flash to flow through the circuit back into the flash and fire the strobe. Your camera can only handle so much ...

If you would mention your concerns, possibly some answer could address some specifics. There are many signals at the Nikon hot shoe. The smaller pins conduct ongoing active communication (Nikon system is named CLS) between the camera and the flash. The flash is told values of f/stop and ISO to display (and the flash can compute and show maximum flash range)...

There are lots of flash choices for your Panasonic Lumix DMC-FZ1000 Digital Camera. If you want TTL auto flash you must use an Olympus or Panasonic compatible flash that will communicate the settings to your camera. For manual flash you can use almost any brand of flash. Here is a link to B&H Photo showing many different Olympus/Panasonic TTL ...

It's the same. The 60D and T3i both came out around roughly the same time and their pop-up flashes and hotshoe have the exact same capabilities. Any strobe that works with and doesn't fry a 60D will work with (and not fry) a T3i. The Canon hotshoe, physically, has been relatively unchanged even from film days. How the electronic communication is ...

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 ...

With remote flash, groups are used to have separate power settings for each group (e.g., Group A shoots at full power, while Group B shoots at 1/2 power, to have 1:2 ratios between your key and fill, etc.), not for separate firing. To switch which lights are firing, you have to manually turn groups on and off between shots. I'd recommend using the YN-560-...

The SB700s have built-in wireless triggers for multiple flash-unit photography. I am assuming all your flashes are SB700/800/900 or compatible. You will not need the Yongnuo RF. The master flash unit on your camera commands the remote units. The flash mode can be set on each flash unit. http://downloadcenter.nikonimglib.com/en/products/245/SB-700.html If ...

I once (this one, I think) tried to stick a gopro onto the same tripod with my dSLR video, but could not contrive a steady enough mount. In this case I did not want them stacked on the same head, so the gopro doesn't move with the main camera panning. My idea was to use it as fallback when the dSLR loses a few seconds between clips, and to replace vibrating ...

In 2011, The New York Times wrote about Doug Mills using such a rig to shoot video with the attached camera while shooting still images with images with main camera. In his interview in December 2013 (at 00:19:49), he shows a Canon 5DmkII mounted on top of a D1x [sic, I guess he meant a Canon 1D x]. Joey Daoud has pushed the idea further to shoot video at ...

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 ...
