Depth of Field
Canon 24-70 L vs Canon 24 f1.4 L vs Sigma 24-70 (Quick note)
All these images are from unedited raw files. They show all these lens depicting as much of the same scene as possible for an accurate as possible comparison. I’ve organised the gallery to show the Sigma lens on one side and the Canon version on the other. At the bottom is the Canon 24mm L images just for comparisons sake.
Focus and recompose is a frequently used technique by many photographers. It is often used when you want to compose their subject in an area of the frame that doesn’t have an autofocus point nearby. On many cameras which have just a few focus points, focus and recompose is sometimes the only strategy that you will have at your disposal. When shooting in bright light with small apertures, this strategy can work just fine. However, when you shoot with wide apertures, focus and recompose can lead to poor results, even failure.
