Manual Focus Lens For Nikon
Some subjects confuse even the most sophisticated autofocusing systems, causing the Nikon’s autofocus motor to spend a long time hunting for its focus point. Animals behind fences, reflective objects, water, and low-contrast subjects are just some of the autofocus troublemakers. Autofocus systems struggle in dim lighting, although that difficulty is often offset by the AF-assist lamp, which shoots out light to help the camera find its focusing target.
When you encounter situations that cause an autofocus hang-up, it’s easier and faster to switch to manual focusing. For the best results, follow these manual-focusing steps:

Though greatly scaled back, production of many manual-focus Nikkor optics has continued in short runs since the advent of AF and AF-S Nikkor lenses, and as a result, Nikon has been able to quickly reboot its manufacturing schedule of a series of classic manual-focus Nikkors including the Nikkor 20mm f/2.8 AI-S, Nikkor 24mm f/2.8 AI-S, Nikkor 28mm f/2.8 AI-S, Nikkor 35mm f/1.4 AI-S, Nikkor 50mm f/1.4 AI-S and Nikkor 50mm f/1.2 AI-S.
Adjust the viewfinder to your eyesight.
If you don’t adjust the viewfinder, scenes that are in focus may appear blurry and vice versa. If you haven’t already done so, look through the viewfinder and rotate the little dial near its upper-right corner. As you do, the viewfinder data and the AF-area brackets become more or less sharp. (Press the shutter button halfway to wake up the meter if you don’t see any data in the viewfinder.)
Set the lens and camera to manual focusing.
First, move the focus-method switch on the lens to the manual position. The setting is usually marked M or MF.
Next, you need to set the camera to manual focusing by setting the Focus mode to MF. (Get the job done via the Information display control strip.) Note, though, that you can skip this step if you’re using the 18–140mm kit lens or certain other compatible lenses, because the camera automatically changes the Focus mode to MF as soon as you set the lens to manual focusing.
Select a focus point.
Use the same technique as when selecting a point during autofocusing: Looking through the viewfinder, press the Multi Selector right, left, up, or down until the point you want to use flashes red.
During autofocusing, the selected focus point tells the camera what part of the frame to use when establishing focus. And technically speaking, you don’t have to choose a focus point for manual focusing—the camera focuses according to the position you set by turning the focusing ring.
However, choosing a focus point is still a good idea, for two reasons: First, even though you’re focusing manually, the camera provides some feedback to let you know whether focus is correct, and that feedback is based on the selected focus point. Second, if you use spot metering, exposure is based on the selected focus point.
Frame the shot so that your subject is under the selected focus point.
Press and hold the shutter button halfway to initiate exposure metering.
Rotate the focusing ring on the lens to bring the subject into focus.
When the camera thinks focus is set on the object under the focus point, the green focus lamp in the lower-left corner of the viewfinder lights, just as it does during autofocusing.
Press the shutter button the rest of the way to take the shot.
When you first start working with an SLR-style camera, focusing manually is intimidating. But if you practice a little, you’ll find that it’s really no big deal and saves you the time and aggravation of trying to bend the autofocus system to your will when it has “issues.”
Set the lens and camera to manual focusing. First, move the focus-method switch on the lens to the manual position. The setting is usually marked M or MF. Next, you need to set the camera to manual focusing by setting the Focus mode to MF. Well then why not try manual focus? All manual focus lenses have a gauge depicting the DOF at small apertures. It will look something like this. Why I’m Going Back to Nikon. Sep 23, 2019. Mar 30, 2019 A “native” lens is one specifically designed for the Nikon Z-mount system, and which allow the following: Full control of autofocus, vibration reduction, iris, zoom and focus control. Electronic metadata like iris, focal length, distortion, fall-off, focus, etc. Continuous auto focus for video.
In addition to the green focus lamp, your camera offers another manual focusing aid: You can swap out the viewfinder’s exposure meter with a rangefinder, which uses a similar, meter-like display, to indicate whether focus is set on the object in the selected focus point.
If bars appear to the left of the 0, focus is set in front of the subject; if the bars are to the right, as in the middle example, focus is slightly behind the subject.
The more bars you see, the greater the focusing error. As you twist the focusing ring, the rangefinder updates to help you get focus on track. When you see a single bar on either side of the 0, you’re good to go.
Here are a couple things to remember about this feature:
You can use the rangefinder in any exposure mode except M (manual exposure). In M mode, the viewfinder always displays the exposure meter.
In the other exposure modes, you can continue to view the exposure meter in the Information display, even with the rangefinder enabled.
Your lens must offer a maximum aperture of f/5.6 or lower.
With subjects that confuse the camera’s autofocus system, the rangefinder may not work well either; it’s based on the same system. If the system can’t find the focusing target, you see the rangefinder display.
The rangefinder is automatically replaced by the normal exposure meter if you switch back to autofocusing, but reappears when you return to manual focus.
You can leave the rangefinder off and just rely on the focus indicator light and your eyes to verify focus. You can also shoot in the S and A exposure modes. It can be a pain to monitor exposure in the Information display rather than in the viewfinder.
But if you want to try the rangefinder, set the Mode dial to any setting but M and then head for Autofocus submenu of the Custom Setting menu. Change the Rangefinder option from Off to On to enable the feature.
Autofocus just keeps getting better. With every new model, more advanced technology allows cameras to quickly pinpoint the subject you're focusing on without missing the moment.
You're probably wondering, then, what this guide is all about.
No matter how good autofocus is, there are still times when manual focus is the better shooting option. When used in the right scenario, it gives a photographer more control over the photo, and in some cases, achieves effects that aren't otherwise possible in autofocus mode.
At first, you're going to feel like manual focusing takes too long. You'll wonder how people ever lived without autofocus. But with just a little practice, manual focusing becomes easier, faster, and the payoff more obvious.
Switching to manual focus
No matter which shooting mode you're in -- from Automatic to Program or Manual -- you can shoot in manual focus mode.
On the side of your lens, look for a switch labeled 'AF - MF,' which is short for Autofocus and Manual Focus, respectively. Happy birthday audio download free. When you're ready to shoot in MF mode, switch your lens to that setting.
At this point, half-pressing the shutter -- what you'd normally do to find focus in AF mode -- is a useless action. Adjusting your focus must be done using the focus ring on your lens. If you have a zoom lens, you should have two rings: a zoom ring closest to the body of the camera, and a focus ring toward the end of the lens.
As you turn the focus ring, you'll see different parts of the shot come into focus. The point at which an object comes into focus correlates with its distance from the lens. In fact, if you look at the top of the lens while turning the ring, you'll see the numbers in the window changing -- the distance in feet or meters that the lens is focused on.
Some advanced or studio photographers actually use these careful measurements to focus on their subjects, literally measuring the distance from the subject to the lens to find the perfect focus. (This is especially useful for photographers shooting product photos in a fixed studio set.)
But in most cases, while you're shooting in 'the field,' precise measurements aren't an option. Instead, you'll need to trust your own eyes to make sure your subject is in focus. Luckily, there are built-in tools to help you do that.
Checking your focus
Here are the basic steps to getting the most precise manual focus:
- Turn the focus ring until your subject sharpens.
- Switch your camera to live view mode (where the LCD is your viewfinder).
- Tap the magnifier button to zoom in on your subject, and use the arrows on your camera to move the area of view. (Alternatively, move your camera to frame the subject, and re-compose.)
- Fine-tune the focus until the subject is crystal-clear.
- Tap the magnifier tool again to exit back to normal view before capturing your photo.
When to use manual focus
Though you can use MF at any time, there are a few specific scenarios that really benefit from it. Often these scenarios are a challenge for autofocus, wherein it either focuses on the wrong subject, or simply can't find focus. Here are a few examples:
Macro. When shooting macro, where the depth of field is so shallow, it's important to have complete control over what exactly is in focus. It's also apparent that autofocus is challenged by macro shots, and spends too much time looking for the focus point.
Crowded settings. If you're trying to shoot a subject in a crowded settings of similar objects, the camera might have a hard time identifying exactly what you're trying to shoot. For example, many blades of grass.
Shooting 'through' an object. You can achieve really striking photos by keeping the object closest to the lens out of focus, and focusing in on a subject further away. In this case, use manual focus to ensure the further-away object is the one in focus.
Low light. If your lens has a smaller aperture, it's going to be difficult to autofocus in dimly lit scenes. So switch to manual focus, and be sure to hold the camera very steady when you get your shot.
Street photography. As Yanidel points out, locking your focus and aperture allows you to shoot continuously without changing either one of those settings. She explains, 'You could spend a whole day without any need to focus your camera by setting the focus ring on 3 meters and the aperture on F11. Then everything between 1.8 and 7 meters would be in focus.'

Landscape. When shooting scenery, autofocus will often find something in the foreground, leaving the rest of the scenery blurred, or at least slightly out of focus. In this case, focus on something far in the distance while you're in autofocus -- this will force your lens to focus on infinity. Then, lock that focus by switching to manual before snapping your photo.
