How to shoot macro themes without macro lenses?

Using near-loop (extension tube)

Near-loop is one of the inexpensive options, its principle is simple, that is, the distance between the lens and focal plane, creating a magnifying effect. The different thickness of the close-loop has different amplification effect, many times to see the near-loop is a group of three of the way to sell. Because the close loop is actually just a cylindrical ring, there is no optical structure inside, so ... Buy a deputy factory can be (but the more expensive OEM near the ring will have AF function). Because the way into the light is different, the amount of light will fall, so in the filming of the need to compensate for exposure, the shutter will naturally slow, so when the close to the camera ring, it is best to match the tripod.

　　

　　

　　

　　

Proximity filter (Close-up filter)

The effect is similar to a near-loop, but one is placed in the filter position, one behind the lens. However, because the proximity filter has additional lenses, the quality of the optics varies with the lens.

Turn the lens upside down.

You can buy a reverse link (reverse ring adapter), turn the lens upside down and plug in the camera. Generally speaking, we will use standard mirror as the benchmark, because usually in 50mm standard lens, out of the magnification will be 1:1, and shorter focal length of the lens (such as 35mm/28mm, etc.) will have greater magnification.

But this kind of shooting way has the same bad place, is because the lens design reverses the relation, therefore the edge picture quality will have a certain degree to drop.

Buy a small DC

(laughter) Want to use the method other than macro lens, in order to achieve the goal of macro shooting, should not be very fond of making macro friends. All of the above three methods can achieve the goal of shooting macro, but not much will have a certain degree of problems, such as the amount of light to reduce the need for exposure compensation (shutter slowing), or because the optical structure reversed or with additional optical lenses, so that the quality drop. So want to picture good, and do not want to shoot trouble the best is to come to a small DC good (laugh).
