Check the electric contacts on the lens and body, and see if they need cleaning?

Pocket wizards and K20 & AF540

Not at all. The TTL information is transmitted through one of the side contacts in the hotshoe, and the Pocket Wizard is not able to transmit other things than the trigger signal.

As far as I know, newer Pocket Wizards are able to control TTL for Nikon and Canon flashes.

Yes, the hotshoe adapter you are referring to will also do the job.

In the setup I needed to have the flash positioned as low as possible, to light the umbrella in the center, and the hotshoe adapter would add height to the setup.

If you want to connect the Pocket Wizard to the AF 540 FTZ flash, you can do it in 2 ways:

With a lot of hotshoe connectors:


Or with a custom made cable:


and solder a 3.5 mm jack to the center and ground, to plug it directly into the Pocket Wizard.

The first option is very unstable, and I recommend the custom cable.

Internal flash as a flash assist

If you want the flash to fire rapid focus assist but not fire to illuminate the scene, you can set the internal popup flash in wireless controller mode.

Press menu. Go to Custom settings. Find the Flash in wireless mode. Select option 2 - wireless controller.

And also remember to set the flash to wireless.

Then the internal flash will do the focus assist rapid flashes, but no illumination.

Set the popup flash on the camera to wireless controller. Then you will not have the light from the popup flash, but only the control blinks.

The combination of a Pentax-A 2X-S teleconverter and a Sigma 70-200/2.8 HSM works - with respect to exposure.

There are no contacts for transmitting focus power and data in the A 2X-S

So only manual focus.

Remote control of istDS without lens possible?

I once had a problem with the focus trap because the lens I used, had some paint on the flange touching the body.

After scraping of the paint, the contact on the body were all short circuited, allowing the camera to recognise a manual lens was attached.

Before scraping off the paint, I tested the hypothesis with a small piece of aluminium foil to short circuit the contacts on the body. Jammed the foil between the lens and the body.

How is the "Tokina 28-80mm"?

Do you actually know, how an aperture ring looks? If you knew that, you would be convinced that this lens does have the aperture ring.

Do you see the ring with numbers 3.8 8 11 16 22 A ?

That is the aperture ring, and the A indicates it will work in all program modes, not only manual with stop down metering.

Good luck bidding on it.

Help with candle/lighter flame photography?
Posted By Chris.Nielsen
Replies: 23

Will the flame be white because it is burnt out? The contrast between the candle wax and the light of the flame might be too big, and the flame will be washed out.

Another technique is to put a colored filter in front of the flash, if you are using this setup, to make the color temperature of the flash different from the color temperature of the flame.

The different exposures are no difference - it is a matter of not having the flame burning out. So go with ISO 100 and as fast a shutterspeed and small aperture to see the color. Do you also need the blue part of the bottom of the flame?

And it is possible to go to Tv-priority and implicit controlling the aperture. If you want deep depth of field, select a longer shuttertime than if you want shallow depth of field.
