发帖数: 275 | 7 2010年9月底买于亚马逊，当时是全新的。如果需要我可以提供当时的Invoice
http://www.amazon.com/Tamron-17-50mm-2-8-Aspherical-Lens/dp/B00
我的40D shutter count 是16289， 在这之前用50MM 1.8 和 Sigma 50MM 1.4
定焦，学生时拍的比较多，后来比较懒，出了定焦换了这个镜头，工作后拍的比较少，
所以这个镜头
应该拍了不超过8000次。由于搬家两次，镜头一直装在相机上。镜头后面的盖子丢了，
我从eBay上买了个代替。有人认为这个镜头有跑焦问题，我用了觉得还好。
出售原因：升级了6D + 24-70MM F2.8L
定价400刀 加邮费。 |

What are the advantages of the PGM aspherical lens compared with the
precision-ground aspherical lens and the hybrid lens?
Sakuma:
Since plastic is used in the hybrid lens, it is subject to environmental
changes such as temperature and humidity fluctuations. However, such changes
have a negligible affect on molded glass lenses. As for a precision-ground
lens, the process of directly grinding the glass takes time and is therefore
not suited for mass production. Since a molded glass lens ... 阅读全帖 |

We posted the filed patent of a 24-70 f/2.8L II way back in October. However
it has now been published as of April 21, 2011. The big omission appears to
be IS. I think it’s safe to say the lens is coming soon.
Other Lenses in the Patent
A couple of other lenses appear in the patent. A 70-300 f/4-5.6L IS, which
has been released. Also appearing is a 55-250 IS lens. This could be a
version II of the current lens. It could also shrink to 200mm at the long

呵呵，只能说是“准牛头”，毕竟用料，做工，手感是不一样的，用18-55比17-55，我
觉得没必要，毕
竟面向人群都不一样。18-55（1 ED and 1 aspherical glass element）对于大部分用
nikon
半幅摄影爱好者是完全够用了，成像质量，锐度自然是同档次中佼佼者。17-55（3 ED
and 3
aspherical glass elements）针对还是用nikon半幅的进阶爱好者，或者部分半专业人
群，还有
弱光条件下要求比较高的用户。毕竟价格都要贵上十倍呢。用来跟18-55比，有点以大
欺小的感觉。真
正要比，用18-55跟同类半幅头（18-105之类）比比就行了，效果自然是不言而喻。。。
要我来选，半幅机身的话，不拿来干活的话，我宁愿选个18-200之类的全功能头，出去
旅游，完全够
了，配上几个定焦（35， 85， 135），人像也不愁了。 |
