High ISO Pictures from the Canon 1D Mark IV

[freelanceshots]

I took some sample ISO images using the 5D Mark II today where the details are as follows:


150mm vocal length, Sharpness 5, High ISO speed noise reduction LOW, aperture Priority AE, TV variable, AV 8.0 for all images, Auto white balance, manual focus


Images taken right after the sun had set where there is a wide range from the shadows to highlights


ISO Levels 100, 800, 1600, 6400, 12800, 25600


--In the lower fairing on the bike what looks like noise is the reflection of the concrete in the beginning--

I used the black bike for the ISO test above as black objects in lower light with higher ISO's always produce more noise. Here is the
same image as above but with better lighting where a more pleasing white balance was
used but I still shot it at ISO 12800.[img]/cfs-file.ashx/__key/CommunityServer.Components.UserFiles/00.00.00.32.66/sportbike_2D00_web.jpg[/img]
