I make it a rule never to borrow my wife's wig.

Pentax cameras tend to be very forgiving of high flash voltages, and Canon very unforgiving.

So it's safer to put a Canon flash on a Pentax camera than vice-versa.

Put a voltmeter across the terminals of the flash when it is charged. I bet you'll find the voltage is under 10 volts. If so, you should be fine.

I confess I'm not a pretty sight at any time!

Actually, Chris, I was being a little mischievous. I think the Slingshot is great.

I don't actually have a Slingshot, I have a Trekker, and I find it a real pain if I want to get something out of it whilst on the move.

I hate the prices these people charge for something that costs about a pound to make in Zengzhou, but I am seriously considering a Pentax Crossover instead of my present bag. It sounds ideal for cyclists.

You want a cross-over bag at a decent price, preferably one that's waterproof, and that doesn't invite attention from muggers.

And if there is some connection with the manufacturer we know and love, all the better.

This post has been going on and on, and nobody has answered the original poster's question.

So I shall.

No.

Great picture.

They are clearly fluorescent lamps, colour-balanced either for daylight or for tungsten, so that in the latter case they can be used to augment ambient interior lighting.

I suspect they are also very expensive, though no doubt very good.

But do you have practical experience of the lamps I referred to, and in what way are they inferior to Kinos (apart from being much cheaper )?

G

They look very much like powerful fluorescent lights to me. Are they not?

G

Yes. Your effective shutter speed (or duration of exposure) is the duration of the flash, which is usually at most 1/1000 second, and often much less.

You will almost never have a problem freezing movement in a studio. The only time it might happen is if you have a lot of ambient light. Solution - switch off the overhead lights, or draw the curtains.

PS: There is an alternative to tungsten. Very powerful fluorescent bulbs are now available, colour-balanced to daylight. Unlike tungsten, they run cool(ish), and don't draw much power. They have an American ES fitting. I'm planning to try a couple.
