Hello

I recently purchased a nikon d7100 and a vivitar sf-3000 flash.

when i press the test button on the flash it works but when I try to take a photo i get nothing.

Is there something I have to change in the menu? or buy a better one?

Please help I need to use it very soon.

Thanks

Hello

New problem.

I bought a triopo speedlight tr 980n.

First use was no problem.
But now everytime I put on new battery it just runs out when I power on.

Please help my holiday will be ruined
 

You need to use a Nikon speedlight. They are designed for Nikon cameras and contain circuitry to make the two compatible.

The power switch has 3 settings: "Off", "Normal", and "Slave On".
If you click it all the way to 'slave on' it may not work in the hot-shoe (it waits for the on-board lash to go off... and the on-board flash isn't activated). Make sure that you only click as far as 'Normal' mode.

just pick the cheapest flash thinking they don't have compatibility issues
