Wireless High Speed Sync
so I'm very glad they added that in the firmware update No disagreement there! By the way, did you notice/agree with my fag-packet sums about HSS flashing? Does it really flash 20-odd times as the curtain-gap crosses the sensor?

Wireless High Speed Sync
By the way, did you notice/agree with my fag-packet sums about HSS flashing? Does it really flash 20-odd times as the curtain-gap crosses the sensor? Sorry... didn't notice them & can't find them :? It has to flash multiple times as the curtain gap crosses the CCD - which is why it's not you...

Wireless High Speed Sync
but this lowest power flash duration of 1/20000 would require 5 pulses to cover 1/4000 seconds, correct? A higher power flash from the AF360FGZ would result in a longer flash duration and therefore require even fewer pulses. It's remarkable that it's so easy to forget that a 'shutter speed' 1/4000s...

Soft Diffuser or Softbox Diffuser
If anyone else is looking for diffusers, and has a thyristor sensor on their flash (for non-TTL shots), make sure the diffuser doesn't block the little window.. Lumiquest has two shapes for their mini softbox models. One, a fully rectangular "lens" for strictly TTL, the other is drawn ...

Homebrew AF-assist
Hello Jonathan, First of all thanks for the compliment regarding my flower. I think very fortunate to be abled (and allowed by my department head) to use this energy spectrum for my photography hobby, not many are. Regarding my Metz flash, it isn't PTTL-compatible, but I don't have to use it ...

Question
If you are thinking of buying a wireless flash (like the two you mention), then you don't need a hot shoe adapter and cables. Furthermore, pretty much the only flashguns that work fully with the K10D are wireless anyway. When flashguns have numbers in their names, they usually refer to the pow...

Question
Ah I see I completely understand it now You're the only one then. :D P-TTL seems more efficient to me, personally. Thank heavens. The Pentax design team can sleep easily tonight... ;) Joking apart, P-TTL is thought to result in more accurate metering, but it does suffer from one huge dra...

Question
It's where the flash emits first a small flash, during which it measures the light coming back and then sets the flash output for the main flash, which takes place a very short time later By the way, just to be clear... It's the camera that does the metering based on the pre-flash's reflection th...

taking photos in the dark
K10/Tammy combo failed to lock onto anything in the dark (murk). How do you take pictures in the dark? Surely . . . you need a K9 . . . sorry, couldn't resist. Fact, your camera cannot function properly in the dark, any more than a cat can see in the pitch black, a common myth. Fact, your came...

taking photos in the dark
I have taken photos in pitch black with my K10D and the built in flash. This strobes to light the scene and aid focus. I assume a compatable flash should do the same thing. The red grid I am aware of was I though, infrared, and I believe the K10D can't see infrared though I might be wrong. As f...

taking photos in the dark
Wow! great response guys, thanks. I was just messin' around in order to learn the equipment. the focus issue was with the flash on the camera and I think Mannesty was correct with the green absorbing it., plus the ground dropping away. The metz grid definitely works as I saw it perfectly across my...

taking photos in the dark
<snip>I did my first product shoot at a client's with the Metz 58 today and the wireless light sensor was less than reliable. I am still getting to grips with it, but it seems to need to be pointing right at the camera and quite close, (10 feet) although it may have been something else.</sn...

taking photos in the dark
I wouldn't read too much into my findings, it is probably me doing something wrong. Light sensors are as cheap as chips, I can't imagine Metz ruining a good Flash with a useless sensor. I'll keep you informed as I get to know it. Incidentally, both Pentax and Metz manuals are really poor. That's w...

Flash Help
if they do manual (or have a sensor built-in for Auto..not ttl) and you can find a slave (optical or radio) that connects (some flash units have built in optical slaves) then yes, they will work with any camera. get a couple umbrella stands, and have fun!

Flash Help
Hi Richard, I went through a similar experience and I bought some cheap optical slaves off ebay for 6 quid each. These work fine indoors when the salves can see the flash or an IR transmitter on the top of the K10D but they just don't cut the mustard outside and you sometimes have problems if ...

Problems using AF-360FGZ (again)
In PTTL, you can simply adjust to +1.0 down to -3.0 stops (that is double the normal intensity, down to 1/8th power. Same amount, but in PTTL the metering is controlled by the camera, so flash ISO setting has no bearing on exposure. If you change the flash mode to A you can change to response ba...

Macro Flash
looks kind neat (maybe not for the bush...) But covering up the front of the flash that way... Does the sensor on the flash body not get used at all during P-TTL operation? Just wonderin'

Macro Flash
Does the sensor on the flash body not get used at all during P-TTL operation? Jamie, P-TTL stands for Preflash Through The Lens metering ;) The sensor on the flash is used for A mode and remote slave. I've been trying to find out dimensions of the SB800 and 580EX to see which would fit the AF54...

Soligor 14-S Flash unit
Cleaning out some old boxes, I found a box with a bunch of photography odds and ends - a bunch of Cokin A filters, a dozen or so round filters (all too small for any of my current lenses...not that any would be very useful on digital...), a 50 foot pneumatic shutter release, and a film leader retrie...
