Close-up lens, in fact
is convex lens. There are three piece of a group, also have one piece. A + 1, +
2, + 3, + 4 to wait for a few kinds specification, the greater the value, the
greater the magnification. Can monolithic use, also can chip stack use, very
flexible.Advantages: investment is not big, is 200 ~ 300 yuan, can buy three
pieces of Camera Batteries a group of the. Flexible and lens after all not as
increasing distance mirror so accounted for volume. A piece of arbitrary
combination, flexible degree is high.
Use close-up lens, aperture will not like using the
increasing distance mirror as decreases, and so can increase than from the
mirror more bold use. Part of the wide-angle additional mirror at the end of a
piece of lens can be off, as a close-up lens is used, so with a wide-angle lens
and certainly buy the wide-angle lens pay attention to a friend oh, you buy Camera Equipment
things, whether also comes with such a useful function,
ha ha.
Weakness: this method
due to the close-up lens change lens optical structure, so the imaging quality
will have a certain degree of decline. But still some solutions. First of all,
pack filters, must buy adapter ring, adapter ring usually have large caliber
and a small-bore two choices. This time, or by large caliber. And if it is lens
the front have filter thread, can be directly after the kind of DC filters or
SLR, it's better to buy a bigger size adapter ring, use a bigger size close-up
lens. Large diameter of filter, can let friends attention oh, you buy things,
whether also comes with such a useful function, ha ha. Using the filter at the
centre of imaging, avoid the edge image quality difference part, get better
imaging. Secondly, in the use of close-up lens, it is best to use the camera's
telephoto end, such doing is also make full use of the middle of the image.
Third, appropriate contraction aperture, aperture is small, the use of lens
edges is less, can further improve imaging quality. A few action joint, imaging
quality decline will not be too obvious.
Three recruit: fall
after lens
This method, a lot of
people said, is to the SLR camera - general is the use of 50 mm header, through
the shuangyang head, but meet at a friendly attention oh, you buy things,
whether also comes with such a useful function, ha ha. Or is the front of the
SLR machine. This method, magnification is the largest, best image quality. But
Camera Flash shuangyang head relatively difficult to find, operating
inconvenience, mobility is poor, also have top-heavy problems, and too much
magnification in general use less, so, perhaps this is the most wonderful
shooting method, but not the most practical.
