Using macro mode to photograpy distant objects?

Amerature photographer here with a few questions.

1) Is there anything wrong with using Macro mode to photograph distant objects in the autofocus mode (10 ft or beyond)? Specifically for a Nikon 7100.

2) When the focus is set to infinity, what is the minimum practical distance where everything will be in focus if the f-stop is set at 2.8? How about it the F-stop is set at 4.5?

3) When setting focus to infinity when shooting video, what again is the minimum practical disance where objects will be in focus?

For clarity, the term "macro" includes shooting closeups of subjects at 1:1, 1:2, 1:3 and 1:4 image to subject ratios. This requires the camera to be very close to the subject. If you want to shoot closeups of distant objects, then you have to walk to that object and shoot closeup.

It seems that you do not know the basics of photography. To learn those, you can buy books or barrow them from a library, but the fastest way is to take classes in photography.

1) You can't photograph distant objects with macro photography, it's a contradiction in terms. You can use a macro lens to photograph distant objects, but a conventional lens will perform better.

2) Depends on the lens fitted.

3) Depends on the lens fitted.

1) No. Macro lenses often make really nice general-purpose lenses. If you can focus on it, you can shoot it.

2) We need the focal length to answer. I'm going to assume you are using the 60mm lens you discussed in 1. With that combo (60mm, f/2.8) at 10 feet your total in-focus depth of field will be something like 11 inches. If you set the lens to the hyperfocal point (which for 60mm & f/2.8 is 211 feet), your depth of field range will be from 105 feet from the camera to infinity. (Look for a hyperfocal depth of field calculator).

3) same as (2). Depth of field ranges in front of and behind the focus point.So, you wouldn't want to focus at infinity. You'd want to focus at some distance less than infinity, and let the "behind the focus point" handle the far distant parts of your scene. This point is called the "hyperfocal" distance. The lens doesn't care if you're shooting still or video.

1 - macro mode is for closeup shots of small objects (eg flowers, bugs, coins) the camera may not focus on distant objects

2 & 3 depends on the focal length - impossible to generalise. The shorter the focal length the greater the depth of field for any aperture.

1. Yes. Macro is meant to take up close to make the subject large. If you use it at a great distance, it's no longer macro. You need a telephoto lens, one that makes a distant object seem near to you.

2. If you want everything focused from a certain distance to infinity, you don't focus to infinity. Set infinity on one end of the DOF scale and the corresponding distance on the other side will be the minimum focused distance. Most digital lenses do not have DOF markings. You're lucky if you have a distance scale even.

3. I understand there's math to this but I never had the patience to study it. I just rely on my old manual film lenses instead and do what I described above in #2.
