The Canon 60D is one of the newest cameras of the Canon line and one of the many using the Digic 4 Sensor. There have been several suggestions that ISO performance varies depending on whether the ISO is a multiple of 160 or 100. To put some of these rumors to rest and to judge the noise performance of the Digic 4 Sensor first hand, I conducted a test to demonstrate these effects.
The Test
The test uses a Canon 60D with a 60mm f/2.8 Macro set to f/5.6 for optimum sharpness. The camera was set to aperture priority with standard exposure in a somewhat dimly lit indoor room. The white balance was also set to auto to demonstrate color accuracy. The test was also conducted using both Canon’s built in noise reduction set to ‘standard’, and also with the setting disabled.
The Results
I really had a difficult time distinguishing differences between multiples of 160 and multiples of 100. For the most part, as the ISO increased, so did the grain. I did notice a lack of sharpness at ISO 640 VS. ISO 800. Though there was more grain at ISO 800, the photograph seemed to lack some sharpness in the details when viewed at 100%. Feel free to comment and let me know your opinions of the test and the results.
