Nikon SB28 and SB28DX Flash

The SB28 will not do ttl on the D1. Only the 28DX does ttl on the D1.

Wally, you need to shop around, especially with the mail order firms. I
paid around $90 less for my SB-28 through a New York mail order firm.
While Ritz is convenient - being a local store - their prices are normally
much higher than competing photo stores.

I have a problem with your explanation.

As I understand TTL flash metering it is the camera and not the flash that is
doing the metering. The camera can then just compensate for the reflectivity
of the CCD. Further the SB-28DX can be used on all film based Nikon cameras
(with an ISO shue). It would have to know if the camera was film based or
digital.

As I see it the difference between the two the SB-28DX can sync at 1/500
(normal sync) where the SB-28 can only sync at 1/250.

Very true. The only difference between the two flashes is the ability for the
28DX model to properly meter with the D1. Recall that a TTL flash (like the
SB-28) relies upon literally reading reflectivity off the film while it is
being exposed. While the BACKINGS of various films are quite unique, the
emulsion side is remarkedly quite similar. Thus, a normal TTL flash expects a
very predictible reflection off emulsion. The D1 camera, however, is quite
different,--no emulsion! When you put a D1 on Bulb and spend a little time
looking inside with the lens removed, you see a wholly different thing,--the
CCD imager. That imager has a blue-greenish tinge to it and is clearly
different than any film emulsion you've ever seen. Thus, a convensional SB-28
would misread that reflected imager,--usually toward overexposing. The SB-28DX
has been modeled to expect both film emulsion and/or a CCD imager reflectivity
and adjust accordingly.
hope that helps! I've had both models (currently have the DX) and you won't
essentially see any feature differences. The DX model does have a slightly
different display as i recall for that added capability with the D1.
