Now, a lot of friends bought, and many use DC DC
jvc bn-vf714u charger friend, all like take some macro-let to get it. Subject matter But some of the DC macro ability is not so good, I'm here to provide some simple improve the ability of the macro to apply to DC and don't want to buy another macro lens SLR friend. Use
A recruit: use from the mirror
In fact, all use from the mirror the friends all know, connectors, away from the mirror for increasing, cameras
jvc gr-d270u charger can put after things far away to put more of the same, in less time, because use taken away from the mirror, recently camera focus will not change, so the distance also can let the shot of the objects are larger than the original. But the use of this action, there is a limit and two shortcomings.
Limitations:
Is can only be used on macro capability is not strong on the camera
jvc gr-d347u charger , or is used in the telephoto end camera. Because of the strong macro ability too often in the macro, DC wide Angle section, distance to often 1 ~ 2 cm, connectors, away from the mirror for increasing after macro to shoot, may not be able to focus. For SLRS for the focus distance is greater originally, so don't need to care about the problem.
Faults:
1, the mirror after use, from the aperture of the lens become smaller, although the camera shows the aperture of the numerical won't change, according to the results of the metering within the camera
jvc gr-d30u charger photograph, and there is no problem. But in fact, the real numerical aperture, should be multiplied by the aperture of the numerical display from a multiple of the mirror: for example, a lens in the 2 x the shuttle from the mirror after, when use aperture, actual for F2.8 number aperture setting is 2.8 x 2 = 5.6. This time, although according to the results, can still shooting metering, but because real aperture decrescent, longer focal length, this time, the shutter speed will be slow to handheld, maybe because of the slight shaking and fuzzy degree, so, it is best to use a tripod to ensure the clear picture.
2, the mirror is often not light, a little weight, oh. So pick up on the camera, easy top-heavy, even on the tripod and we can't really assure smoothly, the shutter, the vibration of the produce, also can cause the failure of the shooting, had better be to use record himself, or by using the shutter release to shoot. The vibration down to a minimum.
The second recruit: use nearly taken mirror
Nearly perturbation, is actually convex mirror. There are three piece of a group, also the monolithic. Have a
JVC GR-D72US Charger + 1, 2, 3, + + + 4 to wait for a few kinds of specifications, the greater the value, the greater the magnification. Can one piece, also can use more pieces of superposition use, is very flexible.
Advantages:
Investment is not big, is 200 ~ 300 yuan, can buy 3 piece of a group. Flexible and lens, after all, not like away from the mirror of volume increased so. Some pieces of arbitrary combination, flexible degree is high. Use nearly taken when the lens aperture will not be like the use
jvc gr-d750u charger as from mirror, so can reduce the mirror is more bold than from use. Wide Angle lens of additional part of the last lens can be unloaded, as nearly taken mirror used, so with a wide-angle lens and just buy the wide-angle lens friend noticed oh, you buy, whether also with such a useful function, ha ha.
Faults:
This method because about the lens change taken mirror optical structure, so the image quality will have the fall of certain level. But solutions or some. First of all, pack filter, must want to buy adapter ring adapter ring, have generally larger diameter and a narrow-necked two choices. This time, or by larger diameter. And if it is lens front have filter threads, can be directly meet filter the kind of DC SLR is the best buy, or a size larger adapter ring, use a bigger size nearly taken mirror. Diameter of the filter, can make great use of the DC
jvc gr-d396us charger central section of the filter, avoid edge horn imaging imaging quality is poor part, get better imaging.
Secondly, in the use of the mirror when nearly taken, it is best to use the camera's telephoto end, such doing is also make full use of the middle part of the imaging. Third, appropriate contraction, aperture, use small aperture lenses edge part little, can further improve the image quality. Several recruit joint, imaging quality drop will not too obvious.
jvc gr-d350u chargerThree recruit: fall by lens
This method, a lot of people said, is to the SLR lens-is generally use 50 mm header, through the head, then in a fall into DC or SLR is in front of the machine. This method, the largest magnification, the image quality is best.
But relatively difficult to find and head into operation inconvenience, mobility is poor, also have the problem of too much, and now the
JVC Battery Charger magnification of generally use less, so, maybe this is the most wonderful shooting method, but it's not the most practical.
