大家好,想请教各位,我用D7000+SIGMA 18-200MM拍人像的时候脸部模糊,请问是跑焦吗?拍风景就没有问题,要怎么解决?

SIGMA的18-200mm也有3个版本,第一支是普通的,第二支是带有“OS”防抖的,第三支是带“OS”还带“HSM”超声波的,一支比一支好,尤其是第三支带“OS HSM”的.
你用哪一支呢?有多老?你有沒有將其發送回simga維修(對齊alignment)

我的是第三支,有OS HSM的。用了半年左右。之前是和D5100一起用不觉得有这个问题,换了D7000才发觉。不曾送回SIGMA维修,因为不确定是机身问题还是镜头的问题。。

Did you forgot to turn off Manual Focus from your D7000 body?
Choose how the focus point for autofocus is selected.
• Single-point AF: Select the focus point as described on page 96; the camera will focus
on the subject in the selected focus point only. Use with stationary subjects.
• Dynamic-area AF: Select the focus point as described on page 96. In AF-A and AF-C
focus modes, the camera will focus based on information from surrounding focus
points if the subject briefly leaves the selected point. The number of focus points
varies with the mode selected:
- 9-point dynamic-area AF: Choose when there is time to compose the photograph or
when photographing subjects that are moving predictably (e.g., runners or race
cars on a track).
- 21-point dynamic-area AF: Choose when photographing subjects that are moving
unpredictably (e.g., players at a football game).
- 39-point dynamic-area AF: Choose when photographing subjects that are moving
quickly and can not be easily framed in the viewfinder (e.g., birds).
• 3D-tracking: Select the focus point as described on page 96. In AF-A and AF-C focus
modes, the camera will track subjects that leave the selected focus point and select
new focus points as required. Use to quickly compose pictures with subjects that
are moving erratically from side to side (e.g., tennis players). If the subject leaves
viewfinder, remove your finger from the shutter-release button and recompose
the photograph with the subject in the selected focus point.

吾得?试下自己做个跑焦测试卡!你部相机有得调节镜头个参数,至于点调就要睇下说明书!

呢度有教点用张卡!其实如果跑得劲就要返厂搞!
