Please help me with the EF-X20
8 months ago

Hi,

I just got the EF-X20 and I don't get it to give me reliable exposure on my Fuji X-Pro1. It overexposes most of the time.

best results so far I got with -1 stop flash compensation, Auto-ISO3200, f2.8 and 1/125s plus turned on built in diffusor to further weaken the flash. It is far from being fool proof like the built in flash in my X100.

Any ideas how to improve things? Thank you!

Take it off auto ISO. Try shooting it at ISO 400 and see how it performs.

Make sure it really has connection to the camera. I had the same problems but then noticed that the flash was no recognized by the camera, i.e., didn't show up as icon on the info screen.

I think startup works most reliable by switching off camera and flash, then turn On the flash and only then the camera. Once it shows up on the info screen, exposure is very good. Nevertheless I often dial it down by -2/3 EV.

BTW, you website is excellent. Astonished how you can maintain it in parallel to your busy professional life.

ISO 400 or 800 instead of AutoISO.

Turn flash on before camera.  This is more difficult than it seems because turning the camera off turns the flash off, but then turning the camera back on doesn't turn the flash back on, so it's easy to respond to this situation by turning the flash back on after the camera is already on.  The flash must be on first for the camera to recognize it and do appropriate TTL exposure.

Thank you. I tried but with higher ISOs because I want to have some balance in-between subject and background. I suspect the the flash might be too powerful compared to the X100 flash which his a guide number of 4,5.

Thank you. That's a strange behavior. Now I know the reason the flash disappeared from the menu sometimes.

Thank you. It's not always easy but we all need to work to be able to afford our gadgets.

How far are you from your subject, f/2.8 might be too much for the ISO that the camera is setting when on Auto ISO. I would set the ISO manually to give you the ambient and flash balance for f/2.8 and 1/125 if that is what you want to use. Auto ISO was it's place, but IMHO not when using flash or when shooting manual with or without flash.

I've explored this a bit with my X-E2.

My conclusion is that your problems are completely a result of either: 1) the flash was not powered up before the camera (in which case all of your exposures will be off, or  2) you are shooting something very close to the camera in a fairly dark room, which causes the camera to select ISO 3200 requiring a flash (at f2.8) that is less than the minimum your X20 can generate.

Auto ISO is not a problem in and of itself.  I can set my X-E2 to AISO3200, F to 2.8, and SS to 1/125 and shoot a variety of shots of subjects varying distance from the camera.  The exposure is always spot on.  If I leave Auto ISO the same, and change the camera to F4.0 and 1/180s and shoot the same variety of shots, I get the same results.  It is only when the flash is turned on after the camera or when I shoot something very close to the camera at ISO 3200 in a fairly dark setting that the flash cannot give the correct exposure.

I hope this is helpful.

Does a manual come with the flash? I'm ordering one.

Yes, but it's primitive. Not much info.

Thank you. That was it. Much more reliable now. It is still not perfect but it is good. I shoot with ISO set at 800 and 1/125@f2.0. Works very well as long as the subject isn't too close.

Thank you it clearly was the flash on first thing. It's a little annoying that the camera turn off the flash and that I have to remember to turn the flash on again before I turn on camera but I think I can manage it.

Again> Thank you. Problem solved. Where can I mark SOLVED to your thread?
