Ray,
I've got a EF-530 DG Super (vs the 610) and what I've found on my K-x is that having the camera in M (full manual mode) with the flash in P-TTL gives me the most reliably exposed images (particularly when using bounce flash). I found the manual (even for Pentax) to be less than straight-forward. I wrote my own quick reference sheet on the modes. The FP (focal plane / high speed sync) mode for the EF-530 DG Super was only accessible when in P-TTL mode.

Looks like there's still a little light in this thread - so to add my two cents:
I was given a Manfrotto Modo 785B by my father-in-law a couple years ago. Definitely not up to typical Manfrotto standards, but a pretty reasonable and lightweight unit for my K-x. I just have to take care not to load it up too much (I think it's rated for ~2.2lbs).

Any luck P12? I've got a new Sigma 530 Super and have plenty of the same questions. (Perhaps the strangest thing I couldn't figure out was using a simple dumb slave - flash triggered yielded a large underexposure with the 530 and built-in K-x flash and a correct exposure with only the K-x built-in flash... but I think that is a topic for another thread.)
Cheers,
Josh

Rob,
I've just bought one of the Sigma 530 Supers. I'm enjoying so far, but there's so much in it in terms of control I'm at a loss to get it all working correctly. Any tips or experience you've gleaned - PM me if I'm doing too much thread hi-jacking.
Cheers,
Josh

I know this thread is all-but-dead, but I've just received a Sigma EF 530 DG Super and found it to be doing the same. Exposure compensation (rather than flash exposure compensation) seemed to work just as well (since it's a simple one-step operation through my K-x rather than a half-dozen button presses on both body and flash).
This is my concern though - it doesn't seem to have anything to do with the metering mode. Going from multi-segment metering on the K-x (as well as multi-point autofocus) to single spot metering and point focus yields the same result.
The odd thing is that the wireless P/TTL function seems to be about right (more testing needed here - this may be a function of the built-in K-x flash correctly exposing and the Sigma's under-contribution not being noticed).

Well - I think I figured it out.
Color me embarrassed. Apparently I didn't actually _take_ a picture without the filter on (as much as I thought I had).
Clearly (see images below) the reflection is coming from the filter. (Just removed the filter, no hood used.) I'll be interested to try again when I get some decent light to see if I can replicate the very distinct reflections, but for now, I'll be shooting sans filter. (The filter was labeled "Rokinon UV Japan" - I understand Ricoh manufactures(d) the Rokinon line - it doesn't appear that it has any kind of coating on the glass.)
Again - thanks all for pointing me in the right direction. Glad to see that it's not reflection from the sensor itself.

Thanks to everyone for the responses. I've got some things to try now... as soon as I see a bright enough day here in the gray of Minnesota's January.
I'll post back with what I discover.

Hi all,
I hope that I've found the right location for this question - I'm a long time lurker, first time poster. I'm relatively new to Pentax/DSLR's (shot with a film Nikon FE and a Minolta Maxxum when in school).
I recently purchased a used SMC-A 50mm f/1.7. Things looked pretty good - very clean, sharp images, etc. However, I've since found that high contrast back-lit scenes give the K-x body and 50mm lens a fit.
I've attached an example image. In the upper left there are blinds with bright back-lighting coming through. In the lower right there is a ghost of the light and blinds circularly symmetric to the original.
Things I've looked into:
1) Lens seems clean - nothing noticeable on either front or back elements, not much dust internally.
2) Included UV filter has no impact - ghosting/reflection is there whether the filter is on or off.
3) "Hand hood" doesn't change anything - perhaps an actual hood (rectangular or circular) would?
Does anyone have thoughts on this? Is this a normal experience for heavily back-lit images on this lens or with back-lit images in general?
Many thanks for any thoughts that could shed some light on this situation,
Josh

Sweetness - perhaps I can get out of the stone-age with my old 35mm film SLR. :)

I too have used Eneloops - I'm not having much luck with them in any device that is very specific about power requirements. The Canon A570 will alert that I have a low battery after a fresh charge from a Maha C204 charger. I wonder if the charge detection circuitry in both the K-x and my A570 are dependent on the internal resistance of the batteries? After shutting off, the Canon can be turned back on and function fine for a time.
