I cannot use LS above 1/800

Postby jfabal » Fri Sep 06, 2013 12:50 pm

I have a DF with an IQ160 and a 80mm LS lens. When I try to use it with flash the camera uses the LS until 1/800, then it switches to FS until 1/4000. Why I cannot use the LS until 1/1600?

First thing to do is make sure your firmware is at least 1.25 or later on the camera body. Also reset the custom functions.

If the problem continues please pay a visit to your dealer so you can test out a different body with your back and lens and we can see if there is something else going on affecting the compatibility.

Camera firmware is 1.25.
But after resetting the custom functions, now it works!
