sfxn flash questions
Hi, I know. Sometimes the manuals are not very helpful. The best thing to do is "play". Wait till you have finished the film and then try various settings and lighting conditions with no film. Get to know when it fires and when it doesn't. When you are happy you think you know what is happening, tr...

sfxn flash questions
In response to my earlier post about fill flash on the sfxn, i now have the results of some trial shots which go some way to answering my questions. On a bright sunny day I took advantage of a passing model (my mum!) and positioned her so that the camera was facing into the sun. I was using my n...

Flash Choices iST DS
The AF360 has a dial/enter control which allows you to choose the mode. The flash has five modes: "P-TTL", "TTL", "A", "M", and "SB" (focus assist lamp only). The modes available depend on the body and the currently set camera mode. If you use an older 4pin extension cable you lose the autofocus b...

360FGZ flash test
Yes, the AF360 does have a test. There's a button on the back marked "Test" :D If you put the mode into "A" then pressing the test button will fire, and the "A" should blink if you've got a good exposure. (Check the manual - I haven't had a chance to look it up.) When using TTL or P-TTL the te...

*istD as wireless controller AND fill-flash?
Works a treat :D There's a custom setting "Flash in Wireless Mode" that controls whether the pop-up flash is used. The default is "On" - which means it will fill in for you. Set it to "Off" and the pop up is used merely to trigger the AF360. You can set the exposure compensation on the AF360, ...

AF 500 FTZ and Super A
There are two different forms of TTL command protocol for Pentax Cameras. The Manual focus bodies (LX, Super A) use an analogue comand protocol. The AF cameras use a digital protocol, but can also use the analogue protocol. Flashes designed for the manual bodies (without an F after the number) us...

*ist DL and Xtra Flash
Surely it's not possible for the Xtra flash to fire before the one attached to the camera - unless you're using the anti-redeye preflash! It must therefore be a synchronisation issue. There is a miniscule delay between the light leaving the camera's gun, being detected by the Xtra flash's sens...

Thyristors and How They Work?
Hi Mac, The sensor doesn't measure ambient light but integrates the light bounced back when the flash goes off. Once sufficient light is reflected for the correct exposure, it switches the flash off. The closer you are, the greater the concentration of the "returned" light. If you double the distan...

AF360FGZ max usable distance
Hi Terri1100. Here would be my advice for a school concert at 25m... raw capture. Manual focus. manual exposure. set your shutter speed to the slowest you can handhold, use the widest aperture that'll allow sufficient dof, (spot metering). (Ideally a fast normal to moderate telephoto.) playbac...

Thyristor Flash with Slave(s)
Hi Mac. If your two lights are not aimed in such a way as to cause the light from your small light to hit the sensor on your vivitar, (ie- 45 degree angles on iether side of camera, ) then the vivitar will cut out at the fstop indicated on the scale. It will in fact read the light reflecting back t...

AF400FTZ Power Shutdown
Maybe someone has some ideas. My AF400FTZ shuts down after a few minutes of inactivity, as stated in the manual. What does not happen, though, is when I press the shutter release on my PZ-1P, the flash does not power back up. I have missed numerous flash shots because of this. Any ideas why this...

AF400FTZ Power Shutdown
There is something wrong with either the flashgun or the camera. The 400 definitely should switch itself back on. G

Synchronisation lead.. err.. synchronisation.
Hi Niblue, I don't know if this is useful info for you, but I emailed Link Direct to see, if I bought another kit off them, whether they would work on the same frequency. This is so that I could use more than one receiver with the same transmitter, for multiple flashes. They mailed back, and th...
