I'm using a 10yr old Nikon F601 SLR with a 3rd party external flash.
The flash is a Emoblitz Auto Focus Zoom 728AFNi TTL Dedicated.
The flash is confirmed working as it flashes when I press the test button. Also, I used it a month ago and it was working fine.
Wat I noticed is the "Auto Check" indicator is not lighted up, but the ready light is on.
The IR on the flash lights up during focus.
Anybody knows wat is wrong? Help!!!!
