Canon 6D flash sync speed

I know for a fact that my Canon 6D has a limitation to sync flash speed at 180 maximum, but when I try to adjust the shutter speed to match that the camera allows me to set it at 160 or 200 only!
Anyone knows how to set the shutter speed at 180?

Hmm, I don't think you can.  1/180 is an in between shutterspeed.  In 1/3 steps you go from 1/200 to 1/160.  Does your Exif data report a TV of 1/180?  I don't own a 6D so I really don't know, maybe in full auto or when using HSS, the 6D forces an odd ball shutterspeed of 1/180.  Otherwise it's got to be a typo in the their specs.

Re: Canon 6D flash sync speed

Hi Samhark. I just played with mine and figured out your problem. I believe you have your HSS enabled like I did. (High speed sync).
Disable it and your camera will actually max out at 1/180th (when your flash is turned on.)

Does that fix it?

Re: Canon 6D flash sync speed

ScottyP,

 

Just for my own curiosity (I don't own a 6D), does the LCD display 1/180 and can you dial in 1/180 when flash is enabled or is it just the exif data that reports it used a TV of 1/180?

 

Thanks

Hi, 7d5d,

You can dial in 1/180th when the flash is mounted and turned on as long as you don't have HSS enabled. As you try to dial up the shutter speed in Tv or M mode, it goes up to 1/180 and just stops going any higher.

Gotcha, thank for the clarification.

Re: Canon 6D flash sync speed

I guess he sorted it out, or sold the camera?

If your exposure increment setting is 1/2 stop (under custom function), then you can dial 1/125, 1/180, 1/250.
If your exposure increment setting is 1/3 stop, then you can only dial 1/125, 1/160, 1/200, and 1/250.
It has nothing to do with the flash, and all Canon camera if you use the 1/3 setting you cannot dial in 1/180 regardless. And if you mount the flash on, like Scotty said, it will stop at the highest speed sync.

Ahh, that makes sense. I've always used 1/3 steps.

Re: Canon 6D flash sync speed

But it won't stop at 1/180 on a 6d if you have HSS enabled, not even if the flash is in the shoe and turned on. It rolls on past that to faster shutter speeds and does not stop at 1/180. I think the OP question was about max sync speed cap on the 6d and why he wasn't hitting the ceiling.
