Remote flash with K20D and Metz 58-AF1
he, he, Sorry.. should have caught this the first time... The Metz doesn't know about PTTL does it? Yes. The 58-AF1 does PTTL. I've sussed it now. I suddenly noticed where the sensor for reading the control signal flashes is tucked away. It's on the left side (from the rear) of the flash und...

How do I use a flash?
By far the best flash to use, unless you MUST have P-TTL, is the AF500FTZ. It's powerful, has full manual control of output, has a built-in sensor for triggering, and also has strobe flash for those who like to experiment. They appear on Ebay regularly at silly prices, but with patience you sh...

Some quick help (I hope)
In fact postage is £3 so I'll probably go with the Chinese option. I've had stuff from China before and indeed got into mild negotiations with a manufacturer of some excellent cleaning products with a view to importing them. But the up front cost of about 4k put me off, large minimum orders. Mike

Sunpak auto thyristor 24SR on Program A and K10D?
You could use any of the Pentax flash cables and adapters(4p or 5p), or a pc cable. If the latter, you will also need a hotshoe adapter with a pc socket, and something similar for the flash gun if it lacks a pc socket. Simpler by far would be to buy a slave trigger off Ebay, and trigger the flas...

Sunpak auto thyristor 24SR on Program A and K10D?
All flash cables will trigger any flashgun in manual mode, whether the camera is designed for P-TTL or not. PC cables can be used on any camera with a PC-hotshoe adapter. The cheapest route is an Ebay flash sensor, triggered by on-camera flash. Next is PC. Radio triggers can be expensive. ...

AF-540FGZ, Problem with wireless mode on MZ-S & ist D
Have used an AF-360FGZ wirelessly many times in the past with no problems in conjunction with an MZ-S and Duracell nickel metal hydride rechargeables. The only times it failed to fire was when the batteries were running low. 6 months ago I started using an AF-540FGZ with the MZ-S, but only a few...

AF-540FGZ, Problem with wireless mode on MZ-S & ist D
Thanks Matt, I was already aware of the points you make and thanks also to you hefty 1, The situations that I have had problems were firstly; 1) in a shaded forest area on an overcast day with my 100mm Macro lens 3-4 inches away from the subject and the flash head pointed directly at the su...

Pentax AF 400t
Auto mode is where the flashgun itself computes the amount of light needed for a good exposure. There is an sensor on the front of the flashgun to do this. You will need to use the back panel of the flashgun to select the ISO that you are using on the camera. This will show you which apertures you...

Can an AF-360FGZ be calibrated?
Pentax always tends to underexpose also without shooting with flash, might this have something to do with it, since Prieni said it use the sensor of the camera with P-TTL?

HS flash in Tv with K10D and AF360
I think you'll find that high speed synch refers to shutter speed, and it only works with shutter speeds faster than 1/180th. When using shutter speeds up to 1/180th the shutter curtains are fully open (the sensor/film is entirely exposed) at the time the flash is discharged. Faster than that, an...

HS flash in Tv with K10D and AF360
Yes Peter, you are right, sorry for the mistake. :oops: I only wonder why they are still there, they aren't needed so far as I know since you can simply cut off the sensor when the time is over. The Panasonic G1 works without one for sure. Does the K20D also still has them? Glad you found the pr...

HS flash in Tv with K10D and AF360
The Panasonic G1, which is close to a DSLR can do 60 - 1/4000 seconds so don't think that's an excuse to use them. Also mechnical parts are slower then simply stopping the electronic signal. The only thing I can think of is because it's there to protect the sensor, might be handy to keep the du...

HS flash in Tv with K10D and AF360
Rob, You may find it easier if you map the ISO to one of the wheels in Tv mode (and Av mode). This enables instant access to the ISO. Pressing the Green button puts it into Auto ISO and adjusting the wheel puts straight into manual ISO ;) (Alternatively you can access ISO directly by holding down ...

Metz 48 AFI
Is it that the power changes? I believe the power is always the same, but it appears to change as the flash just changes the length of time it's actiavted. Could be wrong though, not really the point either! The flash only fires one time in all modes besides HS flash and strobe mode. You get th...

Sigma Flash Problems
As I understood it, all TTL's pre-flash, it's just that Pentax were the first to bring out a new version that worked properly with dSLRs. Nope :) The original TTL is a single flash, through-the-lens metering. Instead of the flash doing the metering (as in the older "A" style flash) the camera had...

Sigma Flash Problems
Matt has explained it very thoroughly, as always. TTL flashes produce only one flash to make the exposure after the mirror goes up and the shutter is fully open. In TTL mode, an additional light sensor inside the mirror box measures the light reflected from the film/digital sensor surface. When t...

Sigma Flash Problems
Nope :) The original TTL is a single flash, through-the-lens metering. Instead of the flash doing the metering (as in the older "A" style flash) the camera had a separate sensor taking a reflective reading off the film - telling the flash when to stop. (The camera's multi-segment meter is only us...
