Shutter Speed

[belladeutsch]

Hi,

I have the Canon RF 24-70, f2.8 L IS USM lens.

I shoot in manual, but I find I cannot go higher than 250 on the shutter speed. Any ideas why this is so?

Hey there!

Which camera are you using?

Canon R5

There are  two possibilities:-

• You have a Speedlite on the hotshoe and it is switched on. This limits the shutter speed to the camera's sync speed which is 1/250, unless you use high speed sync mode.
• You have configured the custom function for Set shutter speed range - it's on the C.Fn2 menu page. If there is a blue star next to the entry on the menu there's some limitation set.

Thank you, I will check. 
I have a trigger on my camera for a strobe. Can that be it?

Yes the maximum flash sync is 1/250th. So to use flash with higher shutter speeds you need to use HSS/ FP flash. But at the cost of less power because the flash now has to pulse to avoid the shutter curtains from being visible.
