![]() You may see a slight shift in color when you pass the point of maximum focus. As you rotate the focus barrel on the lens, the coarser patterns will increase in sharpness and contrast. Start by looking at the patterns representing lower frequencies (exactly which patterns will depend on the resolution of the camera and lens, as well as the size of the pattern relative to the frame). All of these aspects can be observed individually on the chart. in finer features), as well as minimum chromatic artifacts (i.e. where there are larger features in the image), maximum detail in higher frequencies (i.e. Q: In order to see best focus, which areas of the chart should I be looking at when I am focusing the lens on my camera?Ī: When the lens is optimally focused, you will see high contrast in low to medium spatial frequencies (i.e. We have compiled this FAQ to help users get the most out of the charts. ![]() AbelCine has developed our line of Resolution Analysis Charts to allow for accurate, repeatable measurements for any cameras and lenses that resolve 2K, 4K and higher.
