Originally posted by Wheatfield Sure, whatever you say. I expect he went from shooing the action to shooting the ref without changing ISO.
He was shooting at an indoor pool lit by whatever lights they use at indoor pools. The light would have been exactly the same as the light for the ISO 6400 shot.
BTW, what does the light level have to do with ISO performance, pray tell?
Brian and I compared files from my K7 to his 7D today, looking specifically at noise reduction.
The Canon is about two stops better than the Pentax.
I was just pointing out the fact that it is a bright scene, but you seem to take it personally....Let me try to answer this with the same tone you are using to communicate..............
Let me quote DPR when they compared RAW noise of the k-7 vs the 7D....." The 50D produces more chroma noise than the EOS 7D at higher ISOs. The Pentax K-7 is still slightly worse than the Nikon and EOS 7D at very high ISOs but the gap is smaller in RAW. At high ISOs the the 7D and its closest rival, the Nikon D300S, are more or less level in terms of chroma noise".............'slightly worse' is a two stop advantage for you and Brain, hah!...what ever you say.....
What difference does a bright vs dark scene make?....Don't you have a camera, and another to boot with your buddy Brian, why don't you take that apparatus and try and see for yourself.....sheesh! If f5.6, iso 6400 and 1/320 is the same light as f4, iso12,800 and 1/500, I don't know what you and Brian will come up with, but it will be fun to see.........so, if you also say two stops, than I guess it is two stops ????
P.S: Do you enjoy reading such tones ? I don't and I sure don't writing it either.
