Nikon D50 with SU4/SB28, will it work....

[mike_willis1]

I am contemplating using a SU4 to activate a SB28 mounted on a bracket on a

D50. What I am looking for is to extend the flash capabilities of the D50

without spendimg any more money. I know this will work, but I am going to have

the SB28 mounted to the side of the D50, will the lens length track as it does

when the SB28 mounted on my N90s, will it do likewise on the SU-4? Or will it

not because it is basically being slaved off of the internal flash on the D50?

I just recently got the SU-4, so I am no expert with all of it's interactions

with the SB28.

The lens length will not, I believe, track. You will not get full functionality out of either. You

REALLY want at least an SB600 to really enjoy flash photography on the D50.

You will have to use the internal flash in manual mode. Fortunately, the D50 lets you do this, with full control over the power. I'm not

sure what you mean by "will the lens length track", but if you mean,

will the off-camera flash zoom setting (if it has one) change as you change the

focal length of a zoom lens mounted on the camera, then the answer is

"no", since there's no possible way the information could be communicated.

 

If you want to do off-camera flash without spending money on a few SB-800s or SB-600s, you might want to get another flash to go on the D50 that has a non-TTL auto mode. Then you can get things to work automatically while using off-camera flash with the SU-4 or the various Nikon flashes that have the SU-4 cabability built in (like the SB-26 and SB-30).

SU-4 is for remote flash triggering. For flash on a bracket you need an appropriate cord, and not a SU-4. You do not want any pocket flash popper to trigger your SU-4 mode flash - right ?

 

SU-4 is also built into the SB-800, but not in SB-600. SU-4 can be Manual or Auto-TTL.

 

As Peter stated, you need iTTL/CLS compatible flash.

Thanks for the answers. As to the cords I do have a SC-29 cord, but wanted to not use it, since the SB-28 doesn't work fully with the D50, since it's not iTTL capable. I'll probably get a SB600 soon. As to the lens length tracking I mean auto-zooming of the flash in association of moving a zoom lens in or out.

 

Thanks,

 

Mike

Auto zoom for a compatible flash/camera only works if the flash is in the camera hot shoe, the flash head is not tilted or rotated, and the diffusers or domes are not used, and the build-in cards/diffuser is not extended.

 

Try to use the SC-29 cord if you have it, and use flash Auto thyristor (non-TTL) mode, camera in Aperture Priority mode, and turn Off the Auto ISO. If it does not work, use the "mad scientist plan" as described in the post:
