About Taking Pictures

The 50 mm F1.4 AS UMC lens supports a maximum brightness of 1.4. If you take a photo in an outdoor place exposed to sunlight, you may not get a clear image because the subject is too bright. Since the depth of focus becomes too shallow at brightness 1.4, if the subject is not focused correctly you may get an unclear image. Therefore, to get a clear image, focus the subject correctly and then take the photo.
