Hi Doug,

There realy is nothing you can do with the SB-80DX flash. By Nikon's own admission (as well as 90% of working pros out there) it is a piece of garbage as are all of the DX series flashes. There is something in the fill-flash algorithm that does not know what to sample for the exposure so you will get a very wide variety of results. I went through 2 DX flashes, the SB-80DX and the SB-800DX and what I am doing now is using my 8 year old SB-26 flash on Aperature priority and all my exposures are bang on! You have to put the camera in Aperature mode and the flash also and make sure you match the F stop on both. If you want a fill effect you can adjust the F stop on either the flash or camera but this tends ot be a guessetimate at best. The problem exists with all digital flash systems no matter who the manufacturer is. I hope this helps.

I would have to agree that the results with my SB-80DX have been inconsistent as well. Verticals dont work at all.I mean the flash fires but the image is 3-4 stops too dark. Turn the camera sideways and theya re fine. Horizontals can be fine at times.

And from one flash to the next the results go all over the place. Correct exposure, incorrect exp, right on, then who knows what.

But I would love to see where Nikon admits there own product doesnt work.

i would as well... they have "fixed" mine several times. Even replaced it once. It's working really well as ballast in my bag at this point.

I bought a D1x and an SB80DX flash a couple of years ago.

I had two sb28's at the time.

I can't tell you how dissappointed I was with the SB80DX.

My flashed images on D-TTL were all over the place, but mostly underexposed no matter which metering system was set (centerweighted, spot or matrix)

I learned to shoot it either in the A mode where the flash unit itself is doing the monitoring, but mostly shoot it in manual mode.

For "fill flash" outdoors, everything is "overexposed" in D-TTL mode.

However, I have shot probably 40,000 photos at this point, and have no problems with my exposures as I just shoot manual all the time.

Another funny thing, with the D1x, I often shoot at about .7 minus compensation outdoors to avoid blowing out the highlights, and in many cases have the flash dialed down by minus 1 to as much as minus 3 in "flash" compensation.

I found this really strange when switching from film to digital, because outdoors with film, I ususally shot minus .5 .7 or 1 flash compensation for fill flash.

I quit worrying about the numbers and if the image looks good it looks good.

Once I figured out that the SB80DX pretty much doesn't do anything more than my SB28's will, I just as often use my SB28's.

Supposedly, you need the SB80DX to sync with the higher flash sync speed of 1/500th on the D1x, but I haven't had any trouble out of my SB28's being able to fire off at 1/500th of a second. I think they are rated at 1/250th of a second max sync speed.

For that matter, my indoor strobes have no trouble syncing at 1/500 even though they aren't supposed to.

I don't do a lot of "sports" photography or anything where the shooting distance varies quickly from shot to shot, so I haven't found it to be a big problem.

I could see if you were shooting a basketball game or something and the shot distance was varying wildly, that not being able to rely on the camera to TTL the flash could be a problem.

Gee, you don't think Nikon would try to sell a flash and lenses tailored to "digital" that weren't any better than their "film products" do you?

While there are technical justifications that can be made for using special purpose "digital" lenses (like chromatic aberation at the edges) I have yet to see an image shot with a special purpose "digital designed" lens that was any better than with a traditional lens.

I think they get to use smaller glass and charge more to call it a digital lens.

Plus, if they can lock you in to buying a bunch of "digital" lens to go with the smaller sensor, they have no incentive at that point to go with a larger sensor in the future.

Frankly, I'm shocked that they haven't tried to market the digital lenses to film users, because under their theory, the image projected on a piece of 35 MM film, although smaller than the whole frame, should be sharper and better than what you would get with a "film lens". Right?

Mark

Try setting the flash to Auto mode. If your going to shoot in program mode why did you buy a D100? You could shoot in program mode with a much cheaper camera.
