How to use nikon d80 macro

D80 is different from ordinary DC

There is no macro function on the body that can shorten the focus distance and enlarge the image. How big the object can be depends on the lens. Minimum focusing distance and magnification. There are several ways to achieve macro photography

You can buy a macro lens or a lens with a macro function

An ordinary lens with an extension tube or a micro lens A distance lens

Or a reverse lens, etc. Among them, a macro lens has the best effect. A lens with a macro function or a true macro lens

The biggest difference from an ordinary lens It depends on the magnification and the minimum focusing distance. The minimum focusing distance of the general lens is not as close as that of the macro lens. When you find that the object is not big enough and want to get closer, you will find that you cannot focus. Take two Nikon prime lenses with the same focal length. For example. The minimum focusing distance of the 105mm F2D is 0.9m

so its maximum magnification ratio is only 1:7.7, but the minimum focusing distance of the 105mm f2.8 micro can be as short as 0.31m

So The magnification ratio can reach 1:1. 1:1 means how big the real object is

How big its image will be on the finished photosensitive object

For example, the finished photosensitive object is 24 x 16mm

Then a 24mm long object can just fill the length of the photo at 1:1 magnification. But at 1:7.7 magnification, an object as large as 185mm is needed

A 24mm long object can only occupy 1/7.7 of the photo length. In addition, formal macro lenses (not those with macro function) have generally better optical quality

There are more average ones Center-to-edge resolution

Most ordinary lenses have much better center-to-edge resolution. In addition, the design of macro lenses also makes the focus ring longer for manual focus

Today's manual focus More accurate. As for lenses with macro function, the magnification ratio is not as high as 1:1

The optical quality is only the same as that of ordinary lenses. In addition to the price, choosing a macro lens

The most important thing is the focal length that affects the working distance

At maximum magnification, the lens of 50-60mm is only about 2 inches away from the subject

It will scare away subjects such as insects.

Being too close also blocks the natural light source

Long focal lengths do not have this problem

But they are prone to hand shake and the depth of field is very shallow

Focusing requirements are relatively high. As for adding extension tubes

Macro lens or lens reversal have different side effects. If you don’t mind reading in English
