K30 Flash Sync Speed

rp_dxn · 05-18-2014, 07:13 AM

Hello guys, im just wondering, why is that my flash sync speed only get to 1/160 instead of 1/180?
I use external flash Godox TT560 or Yongnuo 560III speedlights to light up my macro shots. Triggers used are Yongnuo RF603.
I really dont, i cannot change the shutter speed above 1/160.. i want to have that faster speed..

Can you help me what's going on?

Don't worry... it's a common question. All you need to do is change EV Steps from 1/2 to 1/3 in the menu system.

Same question here, only with K-50 and YongNuo 460 flash.
If I change EV steps from 1/3 to 1/2, then flash up to 1/180 can be used, but not faster speeds.
As flash duration is 1/800 (Yongnuo YN460 Off-Camera Flash | Speedlights.net), is possible to use more faster exposure speeds?
If I want to shoot sports (motorcycling, ice hockey), then 1/160 or 1/180 exposure time is somewhat slow....:S

It's only possible if you have High Speed Sync available (which isn't on the YN460 I believe). Shooting significantly faster than the sync speed will result in the bottom part of the image being underexposed without HSS. HSS is a protocol to pulse the flash as the shutter slit travels across the image plane.

What Mr. Crane said. My question is why do you need a faster shutter speed? If your aperture and ISO settings require less than full power, the flash fires for a shorter period of time so you can "freeze" fast action even with just the sync speed. This is especially true if there isn't much ambient light and the subject is close.
