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--
