Very confused..
George, With my K100D the AF360 does work as a slave, triggered by the pop-up flash. If you read pages 50-51 in the manual you will see that the AF360 has a built-in sensor for slave work. You will not get the full automatic wireless communication as with the K10D, but still usable, although m...

Terry, I think the point here is that your set-up is not wireless flash, which is the subject of this thread. Wireless flash means that there is communication between the camera and the remote flash in order to ensure correct exposure. As stated, wireless flash works on the better Pentax DS...

Oh dear - if one wants to be pedantic about definitions then my setup is not wireless, at least not as per George's terms. To me it is, because I can trigger my external flash without cables (= wireless). So what if it's not 21st century technology. What is wrong using one's brains to do some cal...

Nobody is being pedantic. "Wireless" is not my term, it is Pentax's, and it has a precise meaning. But you are quite right to say that you can trigger the 360's light sensor with the K100D's pop-up flash. I do the same with my K10D and two remote AF-500FTZs, although I use an AF-240Z ...

P-TTL
So you would have to work totally on manual settings Not quite ;) The K10D supports P-TTL, A and M mode flash guns. I have some very nicely exposed shots using a Metz 50MZ5 set to "A" mode and the K10D set to "Av" (which just happens to be what I use). With the flash set t...

P-TTL
What I meant was not totally manual ;) With Pentax flash guns in the "A" mode you do have to manually set up the camera to match the aperture that the flashgun specifies. Yes, the flash is doing the reading of the light (and not what's on the sensor), but it will take strong ambient lig...

P-TTL
Yes, the flash is doing the reading of the light (and not what's on the sensor), but it will take strong ambient light into consideration in that it is reading a light level and cuts off the flash when the appropriate level is reached. Matt You are right that it will take account of ambient light...

Metz Mecablitz 45 CL-4
I make no apologies for resurrecting this thread but my wife has just bought me a Metz 45 CL3 off e-bay(regular flowers do work) It has no cables or adapters with it. After searching the forum index I realise it's limitations with the K10d. I've also searched the net in an attempt to find out what a...

Metz Mecablitz 45 CL-4
Only wish the PENTAX 's would synchronise at 1.250th sec as does my wife's Nikon FE2 body Just a note for all... the max sync speed is a function of the mechanics of the shutter, and not anything electronic ;) It is the effectively the fastest time where the leading curtain can finish its travel be...

Wireles remote and sync speed on K10D?
Oh, by the way, the dark area is at the bottom of the frame. So that is the top of th sensor. Does the shutter open top to bottom (of the camera) or bottom up? In other words, with the dark area at the bottom of the image, is that an indication of the flash starting too slowly, or the flash fini...

K20D with Sigma EF-500 DG Super
TTL flashes are not supported by either the K10D or K20D. Only the earlier DSLR's, the *istD and (I think) the *istDS supported TTL flash. All of the DSLR's newer than the *istDS support only P-TTL automation as they lack the sensor required to measure the light reflected from the sensor.

pop-up flash diffuser
Thanks for responses. George, the manual flash option does seem like a good budget one if I can find one off ebay in the UK, 3 weeks until the wedding, should manage it. Can you advise or is there a thread on operating a manual flash like this with the K10D, what parts have to be done manually, ...

Help needed please
hs synch is a good suggestion, but there is another way.... in a darkened room with a darker background, your "shutter speed" is controlled by your flash duration. therefore setting your flash to it's lowest setting and your aperture (which controls your exposure with flash) wide, and shutter spe...

Help needed please
Besides, remember 1/4000 second is only 1/4000 per slice as the shutter travels across the sensor plane. It still takes much longer for the entire sensor to be fully exposed, so you will not really get the high speed you want. The af360gz flash at, lets say 1/64th power, is about 1/20000. Plen...

Shooting water splash with K10D and...?
The secret is to use the flash with a minimum of flash power which should get you 1/10000s effective shutter speed. I believe you can get even higher shutter speeds of 1/30,000 with an autoflash by using a piece of paper to feed back the flash directly to the auto sensor. Either use a trigger...

I think I broke my AF360!
It could be a cap problem... but... The P-TTL flsah guns are massively more complex than the older guns! Because the gun has to fire rapidly for the preflash + main flash there is some serious control circuitry in there. And there's the usual problems with fiddling with flashguns - they can be l...

Radio triggers, infrared trigger or long cable
Sorry but that is not an option - that won't work outside - and will have many misfires... Line of sight is true, but not a problem for my specific task (photographing inscriptions on tombstones). Daylight? No problems for me. It has worked every time provided I remember to hold the sensor pointi...

K110D and Three Older Pentax Flashes
Various sources suggest that Pentax DSLRs can handle up to 30v Think you missed a zero ;) I seem to remember it was in the region of 300 to 400V for Pentax DSLRs. EDIT: See : PENTAX: Zvi, Thank you for contacting Pentax USA, Inc. Our technicians indicate the trigger voltage is 300V. This ...

K110D and Three Older Pentax Flashes
Thanks for the correction on the safe trigger voltage. I guess I can use anything in my stable! Re: TTL. It would seem that, if TTL works for the *stD it could work for the others. In film cameras TTL would have to accomodate varying degrees of different films' reflectivity, while with DSLR...
