Can I use a Yongnuo YN-565EX as a second slave flash if my main flash is using HSS?

I’m upgrading from a Nikon D5300 to a D7200 and adding a Yongnuo YN-568EX, which supports high-speed sync (HSS). I already own a Yongnuo YN-565EX, which does not support HSS.

Can the YN-565EX still be used as a second off-camera/slave flash—for example, to light a portrait background—while the D7200 and YN-568EX are being used in HSS mode?

You'll have sync issues with any non-HSS flash when your shutter time is shorter than your camera's flash sync speed. The flash will fire when part, but not all, of the frame is uncovered by the shutter curtains. Only the part of the sensor uncovered by the shutter curtains when the non-HSS flash fires will receive the benefit of the non-HSS flash.

Yes, you can still use the YN-565EX as a second slave flash, but not in HSS.

If your shutter speed is above the camera’s normal flash sync speed, any non-HSS flash like the YN-565EX cannot sync properly. It may either not fire correctly or will illuminate only part of the frame because the shutter curtains are covering part of the sensor when it fires.

So:

  • below normal sync speed: the YN-565EX can be used as a slave normally
  • above sync speed / HSS active: the YN-565EX cannot provide proper full-frame flash exposure

The YN-565EX can still be useful as an optical slave to the YN-568EX, but optical triggering can be unreliable in bright sunlight. If you want radio triggering, you’d need compatible triggers—and for HSS, the camera, trigger system, and flash all must support HSS.

In short: usable as a second flash, yes; usable as an HSS slave, no.
