K-3 flash issue

konraDarnok · 11-06-2013, 04:14 PM

Pretty straight forward test. Take picture, pop up the on board flash and take picture.

What's going on here? EXIF says "flash manual" but it's not on the flash manual setting. It's on the "flash on setting" with 0 compensation, which previously never underexposed like this. I tried "green mode," and it does the same thing. Bug?

Also, just mounted my AF-360, same result.

Just to be sure what I am looking at, the first pic is without pop-up flash and 2nd is with pop-up flash?

I wish I could help, I just got my K3 an hour ago, tried the pop up flash in green and manual mode and all seems normal

Yes, the flash pictures are dark.

Your ISO is 6400 in the first pic and 200 in the second, I doubt the popup flash has enough juice to overcome the 5 stop difference. If the camera was in an auto exposure mode though, I don't know why it chose such bizarre settings.

One thing I avoid with P-ttl is having auto ISO.

My K-5 didn't have a problem with auto ISO and flash. But here is the same test at ISO 200

The flash fires, but it doesn't show up. Like it was in wireless control mode, but it's not. And both the onboard flash and my external flash is doing this. It's busted ain't it? Anyone have any clue what's going on? Is there a menu setting I'm neglecting?

looks like when I forget to put the pop flash as primary and not control.

exactly, but that ain't it. Here's the same test with an AF 360.

Do you see the flash discharge?

Yes. It fires in all modes. But it doesn't show up in the pictures.

Weird. It's like you're only getting the pre-flash.

What about a full camera reset? It's worth a try.

Is there are "harder" reset?
