advice for cheap lighting stands & optical triggers
Have a look on ebay, loads of stuff there. Search for sky4 slave. Are you using normal battery flashguns? If you are, remember that they are much lighter than studio flash and you can improvise a lot more. Microphone stands are cheap, got a couple of boom mike stands in Lidl supermarket, I thi...

flash batteries
Not perhaps what you mean, but older flash units of any power will use C cells or larger, even further back the batteries are simply enormous. I've just thrown away, I mean disposed of, our last supplies of flash powder....Seriously. I was shocked to find it at the bottom of a box in a container ...

Slave triggers.
What I really wish to do is, use a flash unit on a bracket to the side of the camera and a lead to the hot shoe and an independent slave flash to back light or whatever. I do not subscribe to the school that blasts the macro subject fully frontal. I will be using manual flash. Thanks for the prompt...

Pentax K200d and Metz AF36-4
I can't seem to get my head round p-ttl. The built in flash pre-flashes and I can visibly see it. When I fit the Metz it will not do the pre-flash no matter what setting I do on the camera. The flash is virtually new and unused, shall I take it back to the shop?? I would appreciate some advice-tha...

Inside a Church
I have to ask why do they want to put pictures of high value items on a website? It is a nice catalogue for thieves to choose from ! Why not try to enhance the light level in the church - get a couple of tripod mounted site lights, such as: http://www.screwfix.com/prods/14558/Lighti...

K7 Flash Issue?
Just back from a Bank Holiday shoot. Used my K7 with the 360 flashgun. Images burnt out? Even on program? Same gun on *istD and K10 no bother. Is this me missing something or have others had any flash issues? Regards:(

NI-Mh 2500 vs. 2450 batteries .. which can I use?
The number of mAh refers to the capacity in milli-Amp hours, not the voltage, so the only difference between cells of 2450 and 2500 mAh (all other things being equal) would be an approximately 2% difference in the number of flashes (or pictures) you'd get out of them. I doubt you'd notice the dif...

PTTL-HSS mode
Correct. And possibly the Metz as well. G How is this done ? the camera won't let me set less than 1/180, so how is this acheived ? If you have a Suitable Flashgun then First Switch The Camera on and set it to either Manual or TV (Shutter Priority) it works in some of the other modes too but th...

Pentax AF240Z on K20D
It just came today off ebay :) I tried few things and generally I'm quite happy with, but... I know it's not TTL, so far so good - it wouldn't work on K20D anyway. But it has 3 modes: P (Program) A (Auto) M (Manual) Now I've read the manual and looked at some archival posts, but still canno...

Pentax AF240Z on K20D
The reason why the flash "knows" about the diffuser in A mode, is that the sensor on the flash is registering the amount of light which hits it (and which will also hit the sensor or film in the camera). Clearly, a diffuser will reduce the amount of light coming back to the flash sensor, so it wi...

Pentax AF240Z on K20D
Being able to do trailing curtain sync is a function of the flash unit itself, not the camera ;) The interaction with a basic flash unit works like this: * Leading curtain falls * Flash contacts are shorted * Timer * Flash contacts are released * Trailing curtain falls Normally the flashgun ...

Again, thanks very much for the comments. Best thing for me to do is give it a try! Yup! Report back, of course. G

Cobra 700AF – is it safe?
Thanks George. Back to the drawing board and unfortunately the bank account. Shame really as it has a fully rotating head and a thing for firing it remotely, still no good wishing I think it will have to go.

Hanimex PZ4200
I used to have one of these, it dates back to the early 80's. The dediciation is simply shutter speed synchronisation, not TTL. I used it with a ME Super. It was a pretty high specification flash at the time; 3 auto settings as well as manual, with push/pull zoom, tilt and swivel head and second...

Hanimex PZ4200
Follow up : Got it and it works fine ! quite a beast :) Voltage wise gives 11V on Pentax setting but 6V on Standard ! not sure why !? As a comparison my af200Sa gives 7.7V and my af200afg gives 3.1V. More useless info. ;-) Now back to playing :)

In a Dilema: Which Flash should I go for?
Just bought my Metz 58 AF-i instead of the lower end as I wanted to use for future events. Will be trying it out and will post pics that I use with flash over here soon. It cost me SGD$600.00 but i think it will be worth the investment. The price of the 48 was $499.00 so for a $100 more I will ...

AF160 C Ringflash
Same issue as the 50-135mm. Who has one, is it any good and is it justified? Bought the 100mm Macro a couple of weeks back so I'm thinking I need a light for the end of it.... Regards

Looking for a flash with an iluminated set up screen
Or, to put it another way, Distance = GN / f-number, right? So at ISO 100, a Guide Number of 48 at f8 would give a range of 6 Metres? Yes that is it, shutter speed isn't important in this matter. And if you use ISO 200 you will have a GN of 96 so you will have 12 metres. Sorry it's still no...
