EF 17-35mm f/2,8L USM - 1/45s at f/2,8 Frame As You Please, Even With Flash FE lock is the flash version of AE lock. You can lock the flash exposure at the desired spot. With FE lock, the EX Speedlites obtain a natural-looking flash exposure wherever the subject may be in the picture. Compose the picture so that the subject is centered in the picture frame. Then, press the FE lock button to fire the preflash to meter the subject. The suitable flash output for the subject is then calculated and locked. The subject can then be positioned anywhere in the viewfinder while the correct flash exposure setting is retained. Even if there is a bright object in the background, the subject will still be exposed correctly. FE lock for effective subject lighting and flexible framing. In the left photo, the subject is the swordfish on the bow of the boat. Since the sky and the land beyond the sparkling ocean also had to be in the picture, the fish was focused at the center and FE lock was set. Then the framing was changed to position the twilight at the center before taking the picture. The sparkling ocean surface did Dot affect the exposure, and the fish and sea came out well.
