Nikon flash question

DocFrankenstein · Oct 13, 2006

Some nikon lenses report the distance information back to the camera.

If you have the distance and the aperture, you don't need to have a TTL flash metering. You already know how much light is needed for proper exposure. (You know the ISO too)

Question:
Do any of the nikon flash/body combinations have a mode that does exactly what I'm describing?

Thanks

No, the distance feature doesn't create an exposure mode by itself, it simply provides more information for the computer to use in all the auto exposure modes.

In my experience the TTL mode makes the most accurate exposures and the straight auto mode is in second place with me in manual mode in a distant third - particularly with fill flash which the camera does masterfully.

That's too bad IMO

Canon doesn't have this feature either. I wonder why.

Why is it too bad? What is that TTL flash doesn't do that you think some other electronic automation would do?

Ideally, you'd be able to achieve perfect exposures of your in focus subject ALL the time no matter what the reflectance is.

Fill would be REALLY easy - you'd just have to dial a minus 2 in the FEC
