I've tried hunting for info, but some of the existing threads were hijacked and went off the rails... I hate to re-hijack.
Anyway, I have a K-3 and am comparing it to my K-5. Works great in most cases.
Where it is a HUGE FAIL, is when using flash.
I take what you might call "product shots' on the side. Nothing pro, just products for a local thrift store raising funds for a animal shelter. But I have been doing this for several years with my K5 and have a setup that gives predictable results 99% of the time using the flash in PTTL mode. Naturally, I get the stray excessive specular highlight (P-TTL's Kryptonite) and have to adjust things once in a while.
But with the K3 (firmware updated to 1.03), I have a success rate of about 10% or less!!
I see similar behavior with and without specular highlights.
I have to jack up the exposure compensation 3-4 full stops to get a decent image. Its just crazy!
I have a af540fgz attached. I've used full power as well as -1.5 stops of power (P-TTL mode).
The camera is in AV mode at ISO 100 and f/3.5.
I can't figure out what is going on.
I can see and hear that the flash output is greatly diminished with the K3 so that is the obvious reason for the underexposure, but I can't figure out what the camera thinks it is seeing.
One thing I noticed is that with the K5, the EXIF data shows data values in the 9 - 12 range for "Flash Metering Segments".
The K3 on the other hand is showing all 0's!! WTF?
Is my new K3 broken?

Oh, important info.... the flash head is pinter straight up with a large reflector -- somewhat like the Rouge Flashbender.
I have not shot with the head straight forward yet (I almost never shoot that way but I guess I'll give it a go for testing).
