Digital SLR and P-TTL flash guide
I have noticed that my GX20 (K20d equivalent) massively under-exposes PTTL flash shots when I have a split-image focussing screen fitted. Haven't found any elegant solution to this other than to replace the focussing screen with the default one. Wondering if any Pentax users have seen this too...

Digital SLR and P-TTL flash guide
Simon, All metering for P-TTL, as well as for non-flash metering, is performed through electronics housed in the top of the pentaprism. The same 16-segment meter sensor is used to evaluate the preflash as is used for normal exposure (though it appears that for flash exposure the whole frame is used...

Digital SLR and P-TTL flash guide
Just thought I'd add an update to the exposure compensation... :D (When using "Slow" flash mode, fiddling with a K5 + AF360) * The regular +/- adjust affects the ambient light. * The camera's flash +/- affects all flashes controlled by the camera. * The flash's compensation (using "S" bu...

Pentax Bounce Flash AF22OT TTL 645+AF
I searched for ebay for 'Centon'. :wink: Note this doesn't have the controlable power that George rightly points out is a bonus, and I have to say that I have no idea what the guide number is, but would guess 30 from the model number. Oh, just checked back on the ebay page and saw you got it!...

Thoroughly confused about PTTL & wireless
Yes, wireless flash is working. The only thing that doesn't seem right is the lack of adjusting the light output to maintain a proper exposure. Of course, putting the camera in P mode rather than Av seems to make the flash adjust its output. So I'm sort of lost on how exactly wireless PTTL work...

Thoroughly confused about PTTL & wireless
Have you set the flash to W in the function menu on the K10D? Yep.... unfortunately the wireless is working. (i.e. all my settings are correct). It just isn't working correctly. I am probably going to go back to my other issues and see if they get resolved with the 360 on the hotshoe. It is s...

Thoroughly confused about PTTL & wireless
Good idea on the lens issue. Just read another thread on something about that yesterday. Anyway, I was using my old SMC Pentax-FA 1:14 50mm lens. switched to the new kit 18-55mm and have the same results. OK some further observations... When the 360 on camera is in master mode it fully take...

Thoroughly confused about PTTL & wireless
I generally have been shooting the remote flash through a brolly. I thought I had mentioned that in my initial post but I see after all the copy/paste and re-writes that I left that out. (stupid!) Although honestly didn't think the flash needed to "see" the subject for PTTL. Could th...

Samsung flash on order
Apparently (counting no chickens, especially given the postal strike), my Samsung SEF-54PZF at Amazon is in "being prepared for delivery" state, and will be despatched soon. Possibly more of interest to others, however, is that it's currently showing 2 in stock at Amazon, at the same £1...

Hacking a Pentax 4P grip for the AF540-FGZ
You may have seen one of these: http://www.bdimitrov.de/kmp/flashes/misc/grip.jpg It's a 4P, old style grip for the Pentax systems. It's very compact, has a great detachable camera plate and space for 8 x AA batteries inside. However, the hotshoe mount shorts out the extra pin on the AF540 an...

AF540FGZ, K10D, Wireless Flash problem
Slave 2 mode will cause the flash to behave as a dumb flash. In other words the flash will fire on the first light it sees. The pop-up flash and any PTTL aware flash in the hotshoe will fire a pre-flash. This will cause the dumb slaves to fire, but no in sequence with he mirror being up. Thee is...

Studio Flash triggering
I think the message being conveyed her is that, your problem is the exception, not the rule. try to find out what equipment was being used, tell us more detials about how you set about problem solving the issue. I'm betting it is either the hotshoe adaptor, or the pc cables or the polarity issue. ...

Studio Flash triggering
Not sure if this is the same problem but a few weeks back I went to a studio flash workshop where there were several light setups. The setup using a radio trigger worked fine with my K10 but there was another setup using sync cable or IR trigger. Unfortunately having only had the camera a couple...
