小弟是Tamron 17-50 f2.8 的镜头,配nikon D90.常常会出现foucus不到的问题,就算是关电再开电也是一样,一定要把镜头拆开再装回才可以再foucus.请问这是镜头还是机身出了问题? |

換個角度與距離也focus不到 ?
那麼可以試試manual focus嗎 ?
如果manual focus能。。。。auto focus不能 ~
應該要去check一下了 |

Tamron 出事了
Interesting issue with Tamron Lenses
I received this information a while back, I didn’t post it until there was some kind of response from Tamron.
The following is a direct quote from the folks that found the problem. Tamron’s response is at the bottom.
i am a member of the german dslr-forum (www.dslr-forum.de), which is probably the biggest german speaking community regarding all DSLR-topics (not only Canon). We observed a phenomenon where the followings lenses won’t use the outer cross-type sensors of EOS 40/50/60/7D cameras right.
The lenses that show this problem are (all Tamron):
17-50 f/2.8 VC 60 f/2 Macro 70-200 f/2.8 10-24 f/3.5-4.5 To get a bit more into the detail of the problem – on the 40/50/60D cameras the outer cross-type sensors only work as line-type sensors. To be a bit more correct, they actually work in the same direction as they would work on cams like the 30D or like the 400/450/500/550D. When it comes to the 7D the outer sensors are also only working as line-type sensors (but it seems, that the EF 50 1.2L also has problems to use them correct).
The center cross-type sensor does work at least as a single-cross type sensor (infact we don’t now how to test if the center sensor is working as a dual-cross-type sensor like it’s supposed to work with those f/2.8 and better lenses).
Tamron seems to not know about this behaviour so far. Well – at least, they didn’t confirmed the problem and only said, that they will investigate this.
Maybe a small addition – the Tamron 17-50 VC uses the same lens-ID as the EF 35-80 – maybe you’ll have the chance to check whether this Canon-lens performs correctly or not.
The link to the thread is: http://www.dslr-forum.de/showthread.php?t=732360
Tamron Europe’s Official Response
Dear Mr. S.,
we were able to reproduce the situation where the Tamron 17-50 VC (B005) and the Tamron 60 Macro (G005) won’t use the Canon EOS 50D cross-type sensors correctly.
We have given this information to Tamron in Japan and we are expect an answer very soon.
Best regards
Tamron Europe GmbH
Thanks Joerg |

对啊,在 auto focus 的时后才会出现的问题 ,当你出现这样的问题时你怎样解决的呢?你知道是哪里出问题吗? |

是換角度與距離也focus不到咧(在发生那状况时),刚要试试manual focus可是auto focus不到的状况没出现,通常在紧急要拍是才出状况的,哈哈.谢谢您的解答 |

你是nikon lens 也会出现这样的问题,应该是不关tamron lens的问题囖 |

你是不是距離太近了 ? 所以focus不到 ?還是object太暗了 ?(就像晚上在路邊在拍黑人那樣 ~ 很難focus )
還是對著天空拍 ?(有時會focus不到的。。。有時對比不是太強因為相機不知道要focus那裡) |

明白你的意识,比如说头发或是云,也是focus不到的.我所focus的是一些亮的物体或脸部,我的应该不是技术的问题. |

这个就不清楚是不是相机或者 lens 的问题
最近因为比较忙,差不多3个星期多左右没使用
前几天拿来拍照,发现不能 focus 和不能拍
重新开机那些也没用
最后把 lens 拆开再装回去就可以了 |
