I don't know if anyone can offer up any explanations for this but I am baffled.
Myself and my son  Connor went out this afternoon to shoot some moving stuff just to see what we could achieve.
Anyway it was a bright day but a little overcast.
We wanted to use as fast a shutter speed as we could get away with in order to freeze the motion.
This is where a dicrepancy between our two cameras came in to play.
Connor was able to run his D70 with Sigma 70-300mm at ISO400 F5.6 at 1/8000s with just great exposure.
Whereas my D200 with 18-200mm set to ISO1600 F5.6 was slightly under exposing at 1/3200s
Neither of us were using exposure compensation, so I am totally baffled.
Oh yes and of course his pics were just great and mine were simply shocking, a fact that seemed to amuse him.
Anyone have any idea what could be going on here?

| Could be that you cameras were metering diffrently, or on different areas. |

| What metering mode were you each shooting with? |

Connor was using Matrix and I was using Spot, although we were both in manual mode so this shoul dmake no difference should it?

That is the difference. Spot metering has a vastly different effect than matrix. Try the experiment again and both use the same type metering.

I will for sure many thanks Peter, I have no idea why I was in Spot Metering mode mind you lol.
Will this have any impact though if I was in full manual mode? |

It depends on how you arrived at the settings you ended up using. If you had the identical exposure and iso settings in both cameras, both set in manual, yet one gave under-exposed results but not the other, then you still have a puzzle to solve as the metering method would be irrelevant. Is that what happened?

No, if you were in manual mode the metering would suggest to you if you were over/under exposed with the display in the viewfinder but the metering would have no impact on the exposure if you were making all of the exposure decisions for the camera. I would see if you can duplicate the issue - point both cameras at a wall, set the exposures to be identical and see if the images are approximately the same brightness. If they're off by a lot there may be a problem with one of them.
