I was looking into getting a Canolite D to use with my x100 since it's good flash unit and a perfect stylistic fit. I was wondering if it would be compatible. I read a single comment on another forum that old flashes and new cameras don't mix due to voltage differences. Is this true?

I can't answer that specific flash, I have my dad's old Cobra CX150. I don't know what year it's from, but it works fine with the X100. THough I couldn't say anything about the voltage. There's no controls for power etc, its just flashes. I tried it the ones and that was it.

I tried my Canon Speedlight on it and it worked. I had to take some test shots to get the exposure right. The flash was also very top heavy, as one might expect.

Mattmaber, I like the dual strap arrangement you have going on here. Good idea. I recognize the Gordy's wrist strap, but what neck strap is that? thx

mattmaber

@ducevro thanks. Thats cam-in. Bought on eBay. I can never decide neck or wrist so having both is useful. I used the Gordy on my Nikon D90 over the weekend so am getting another one to go with the sling style strap that attaches to the tripod base

Looks good. Share the photos after the shots using this flash.

Using an old flash on a modern digital camera is a common question. Here's the basics.

Old flashes often have a trigger voltage of several hundred volts. With the old mechanical shutters, that was no problem. Modern cameras with electronic shutter control use a transistor to trigger the flash. Applying several hundred volts across it will destroy the transistor eventually. Just because your old flash fires, doesn't mean it's safe. Your x100's trigger circuit will die eventually if the flash voltage is too high.

To see if you can use the flash safely, place the probes of a voltmeter/digital multimeter (set to DC voltage) on the two contacts on the flash shoe (side and tip) and switch it on. If the voltage is 6V or less, it's safe. If it's more than that, don't risk it.

There is a solution, however, for flashes with high voltage triggers. You can buy a flash adapter for about $45 that includes a protective circuit that drops the flash trigger voltage down to 6V. It slides onto the flash shoe and fits onto the camera. A popular one is called the Wein Safe Sync (http://www.amazon.com/Wein-Products-W990560-SSHSHS-Safe-Sync/dp/B00009UU18/ref=sr_1_1?ie=UTF8&qid=1314638569&sr=8-1). I've used mine for several years with my old Vivitar 283.

@DonC - understood. It isn't really of any practical use as there's NO control over the power, I just wondered if the X100 would fire it - and it did.

mattmaber

I wish Fuji would make a nice retro styled flash to go with the X series. The current 2 options are hideous on the X100.

Mark2000

What I read, though, was that the voltage difference would actually harm the camera. That would make me sad. Possible?

mattmaber

Sounds like thats what @DonC is saying.

Here's a compiled list of flash models and their trigger voltages: http://www.botzilla.com/photo/strobeVolts.html

And this is a good article on using vintage flashes with modern cameras: http://silverbased.org/vintage-flash/

Fuji Support / 40V or less is safe.

This means a Nikon Sb-600 could safely be mounted on the X100... hmmmm... interesting!

mindthemix

Definitely a SB-600 fires on the x100. I'm using it for off-camera.

I contacted Fuji about the trigger voltage an as follows their response:

Dear Federico,
Thank You for your email. The maximum trigger voltage the X-100 can accept is 50Volts. We hope this information helps.

You use it off camera but have you tried on?
Guess it just fires... No TTL information is being pushed or anything right?

mindthemix

yes, it fires on camera as well but only in manual mode.

Has anyone tried a Contax TLA200? I've been thinking of getting one of those for the X100. I hate the look of the Fuji ones, especially considering they charge double the price of the Sunpak flashes they essentially are.
