Because the D40/x/D60 lacks an on-board focus motor, a lot of owners of these cameras are shooting with lenses that cannot autofocus on their cameras. For some, this is no big deal, for others, it is a deal breaker. For the latter group, the best solution is to either buy only AF-S lenses and third-party equivalents, or else upgrade to a different Nikon body and get autofocus with any AF lens.
For those who are going to be manually focusing much or all of the time, but maybe aren’t naturals, here are some tips:
- Make sure your diopter is set correctly. It’s the slider next to the viewfinder. It’s used to adjust the viewfinders focus making it easier for those who wear glasses to see through it. Use it to make sure the AF brackets look sharp. If the diopter is set wrong, it’s hard to get good manual focus results.
- Use the focus confirmation dot. It’s a green dot in the lower left hand corner. If it’s blinking, your focus is iffy, if it’s solid, your focus should be more or less right on. However, this is in reference to your selected focus point!
- D60 users get an even niftier electronic rangefinder. Using the P,A,S modes the exposure value in the view finder will turn into a focus meter. This is a visual representation of how well you are focusing. If the bar is in the middle, than you are properly focused. This works best when using Single Area focus mode.
- Use good technique. Keep your arms close in, use good posture, control your breathing
- Zoom in to check sharpness. After taking an exposure, zoom in on the LCD to verify the sharpness and than adjust the focusing from there
- Shoot at a higher f-number (but not too high!). This will make the Depth of Field larger so it will be easier to keep your subject in focus. Setting the f/stop to f/8-f/11 in general will produce the sharpest photos and has wide depth of field.
- Try shooting on a tripod. If you’re struggling, try shooting on a tripod for a while, until you get comfortable with how the lens focuses. This allows you to concentrate on focusing. Tripods are also a great way to ensure that you get the sharpest image as there will be no camera shake.
- Get a Split-Prism Focusing Screen. If you can afford to and don’t mind the installation process, a split prism focusing screen will provide more positive confirmation.
- Magnifying eyecup. Some folks find the humble DK-21M magnifying eyecup helps with focusing
- Get an older lens with a better focus ring. The best manual focus experience is had with a lens that has a good focus ring — smooth, well-dampened, etc. This is usually found on older, dedicated MF lenses.
- Control your front-back motion. If your body is drifting forward or backward, this will shift the plane of focus, and this can spoil shots with shallow DOF, even if the drift is only in millimeters. Alternatively, if you’re shooting handheld macro, this is how you adjust the focus — by moving the camera forward or backward.
- Shoot bursts. It may help to shoot bursts, either while holding steady, or while rocking forward/backward, or while tweaking the focus ring.
- Practice, practice, practice
