It should be close to that infinity mark.įor lenses without a focus scale (and infinity symbol), switch to Live View, zoom in on very distant object, and manually focus the lens. While out shooting during the day, auto-focus on a very distant object and then note the reading on the focus scale (if your lens has one). Really get to know how each of your lenses works with the camera body that you have. So how is one to find where infinity focus is on a particular lens? As with most other things in photography, this is going to be much easier if you are intimately familiar with your gear. To muddy the waters even more, most kit or lower-end lenses don't even have a focus scale or an infinity symbol. OK, we've already established that infinity focus on many lenses isn't actually on the infinity symbol on the lens. A full moon made focusing on this landscape a breeze. If you are shooting something very far away, and depth of field isn't a concern, focusing to infinity is the best approach. ![]() Infinity focus will help you to achieve that sharpness. The problem with using hyperfocal distance is some situations is that the background isn't as sharp as it should be (or as sharp as we would like). That distance varies, depending on focal length, aperture, distance to subject, and even sensor size. ![]() In that situation, we typically want everything from that foreground to the background (infinity) to be sharp. This is important in landscape photography, particularly when there is a foreground element relatively close to the camera. Simply put, hyperfocal distance is the closest distance at which a lens can be focused while keeping objects at infinity ‘acceptably sharp'. This discussion could quickly go down a deep, dark ‘rabbit hole'. Furthermore, infinity focus is often not actually right on the infinity symbol, but is rather somewhere just before reaching that mark on the lens. The problem is that the focus rings on most modern lenses don't stop turning when they reach the infinity mark. Some lenses have a focus scale and even an infinity symbol (∞). Finding infinity focus is a little different on each lens. That is essentially what infinity focus of a lens is, where very far subjects are sharp. Depth-of-field isn't really a concern here, but knowing that those far away things are in critical focus is. Things such as the Milky Way, stars, the moon, or other astronomical objects are far away. It is important to note that these tips are primarily aimed at nighttime shooting where infinity focus is desired. Turn off auto-focus and manually focus the lens.Set the flashlight in the scene some distance from the camera and auto-focus on that.Use a flashlight to illuminate an object and auto-focus on it.Auto-focus on the moon or a light on the horizon, then turn off auto-focus on the lens or camera.Auto-focus on a distant object during the day, then turn off auto-focus and lock the focus ring until the night shoot. ![]() The following techniques have proven to be effective, depending on the situation, and are discussed in greater detail in this article: It just takes a little bit of practice to learn and perfect the techniques that work best. However, there are ways to overcome these obstacles and come away with some fantastic night photos.įinding focus at night isn't as difficult as it may seem. Depending on how dark it actually is, and the availability of distant light sources, the auto-focus function of your camera may become very difficult if not impossible to use. Our cameras have a much more difficult time ‘seeing' when it is dark, just like we do. The reason is really pretty simple and should come as no surprise. One of the biggest challenges when photographing at night is capturing images that are in sharp focus. ![]()
