Sb-600 and d80 sync, connecting, off camera..

The best flash for YOUR D80 is the one that best suits YOUR needs. Both the SB-800 and SB-900 are compatible with the D80. So is the SB-600, which is lighter and smaller.

It's the Inverse Square Law. Light drops off as the square of the distance. If an object is twice as far from the light source it only receives a quarter as much light. So, if the subject is lit properly then the background will be dark.

This is a law of physics. However, there are several things you can do about this. One is to move the light source. Another is to have more than one. The D80 can control other flashes, so you can use the D80's pop-up flash to light the subject and the SB-600 (or more than one of them) to light the background. Another possibility is to bounce the flash off a white ceiling or wall to soften and diffuse the light. Another is to use slow-sync, leaving the shutter open longer to let the background illuminate. You can read more about this in the manual.

It sounds like you're trying to use the SB-600 off camera, as a slave flash. While the SB-600 does indeed have slave capability, the D40 does not have the ability to function as a commander. Thus, the SB-600 is being triggered by the D40's pre-flash.

As stated above, the D40 does not function in commander mode. You can mount an SB-800 or SB-900 flash unit, which will function as a commander as well as a flash. Or you can mount an SU-800 commander unit.

Alternatively, you can switch the D40 to manual flash mode so as to eliminiate the preflash. However, you will then have to calculate the proper exposure yourself.

Definately a settings problem. The camera will only syncronize on one specific speed. Youe best bet is to use auto. For manual, you'll have to set the shutter speed at the sync speed.

Flash Sync Speed

up to 1/250 X-Sync Speed

up to 1/8000 FP High Speed Sync

Red-eye reduction
Red-eye reduction with slow sync
Rear-curtain sync
Slow sync
Front-curtain sync (normal) Flash Sync Modes

1) i-TTL: TTL flash control by 1,005-pixel RGB sensor, built-in flash, SB-800, SB-600, SB-400: i-TTL balanced fill-flash and standard i-TTL flash
2) AA (Auto Aperture-type) flash: Available with SB-800 used with CPU lens
3) Non-TTL Auto: Available with Speedlights such as SB-800, 28, 27, and 22S
4) Range-priority manual flash; available with SB-800 Flash Control

ok,
try to set the menu item for Auto FP to ON (it works in P,S, A, and M modes only) that will activate the Highspeed Sync when you are using the SB-600 flash unit, set the flash mode so the indicator shows the off position (the line thru the lightning bolt symbol) on the top inidcator menu in the its next to the red eye redution icon that will keep the built-in flash off even if you need it in low light. hope that works for you.

I also purchased a Bower 724AFN to use with my D80, and experience the same problems. Received confirmation from Nikon that this flash unit is not compatible with the camera. I then purchased an SB-600 flash, and haven't looked back. It's worth the extra money for this high quality unit; fully compatible, and compliments the TTL features of the D80. I'll never deviate from original Nikon accessories again.

In whacky situations like this it is always best to re-set your camera and flash settings. Somewhere on your D80 you will find two function buttons with small green dots next to them. These are the resets. Push both in at the same time until the display LCD flashes.. The camera is now reset to default settings.You will now have to re-set your FV button to the custom setting you had it at before.

Also, reset you flash by turning on the power and removing the batteries and re-install them.

sb-600/800 make a distinct motor-spinning noise when zooming, this is normal. Any grinding/clicking noises are not normal.

This can be that the flash sync speed of the camera is not correct. There may not be enough exposure from the flash to the subject during the opened curtain (shutter) sequence.

The 60CT-4 was not made for digital cameras.
It does TTL on film not on CMOS or CCD sensor.
