ISO impact on sensor performance

Each of us has our own criteria we use when selecting which camera to buy. Sensor performance, handling, ergonomics, auto-focus, lens selection and other factors can all play a part. Many photographers are very interested in the sensor performance of their cameras, and this short article discusses ISO impact on sensor performance.

Often when we start out as photographers we hear more experienced folks talk about the importance of not stopping a lens down too far as to avoid the effects of diffraction.

We may find this confusing because from a composition standpoint we often want to achieve deep depth-of-field, especially with landscape photography. Stopping a lens down to achieve this degree of depth-of-field seems quite logical.

This begs the question whether we really need to care about diffraction. Continue reading Diffraction
