发帖数: 5617 | 1 For Photokina in September Sigma is rumored to announce the previously
rumored 24mm f/1.4 Art lens and a new 14-24mm f/4 with OS. The 24mm lens
will be priced at $1,099 and the 14-24mm will be $1,199. The 14-24mm will
have an 82mm filter ring.
After the success of the 35mm f/1.4 and 50mm f/1.4 Art versions, a new 24mm
lens would be the next logical step. There were also rumors for a new 85mm f
/1.4 lens, but I have not heard anything on that model. Sigma may also
announce the future development ... 阅读全帖 |

发帖数: 13752 | 3 你后面说的，不就是我说过的意思吗？DxOMark Score和Sharpness是两回事。
不同的f值下，DxOMark Score最好的时候，Sharpness不一定最好，反之亦然。
你给的图表数据，说的是24mm在f/2.8时DxO评分最佳（DxOMark Score best at f-24mm
& f/2.8），分数为26，差于24L，但sharpness是17p-Mpix；24L在f/2.0时DxO评分最
佳，为28，但sharpness是16-p-Mpix，差于24mm。你因此就说24mm的“分辨率很牛啊，
比24L都强”（你的原话），忽略了一个是f/2.8时的sharpness，一个是f/2.0时的
sharpness。F值差这么大，比sharpness没什么意义。
24L最好的sharpness是在f/2.8，不是f/2.0。

全幅相机建议：24mm和85mm
24mm，是非常必要的。人文、出游都离不开。
35mm，完全没必要。
50mm与85mm之间，情愿选择85mm。拍人像、静物时，勉强可以虚化一下。
四支头，四选一，24mm。四选二，24mm、85mm。四选三，24mm、50mm、85mm。 |

发帖数: 1941 | 11 入手5D2以后，先玩了几天17-40，后来这个头卖了，手头没什么好的广角头了，就想起
来把放在箱子底的Olympus Zuiko OM 24mm/2.0手动头拿出来接上5D2。原来对这个头的
印象不太好。用在500D上，38mm的等效焦段比较尴尬，而且500D的白平衡跟这个头不太
搭配，照出来的照片颜色发粉色。用5d2照了几张后，发现这个头的表现真是牛啊。根据我的
实测，中心分辨率秒杀17-40(据说17-40的中心分辨率还是很牛，但是我的实测证明还
是不如，也许是不同测试距离)。边角就更不用提了。
没有同一场景OM 24mm/2.0和17-40mm L的直接PK (17-40卖的早，没有正名的机会了，
但是有这个头的xdjm可以做个测试，看看分辨率能否达到我这个OM头的测试结果）。
Lightroom用的不熟练，简单crop了一下，可能照片还有损失。参数在原尺寸图的下面有介

lens, I am not sure the IQ will be better than prime. and I have 35, 50, 85
primes.
2. 24mm f/3.5L TSE, the is a great lens, for both architecture and landscape

Sorry cannot type Chinese on this computer.
I have a T2i, and saw a 24mm f/1.4L for sale at $980 on CL. But it is
generation 1, not the II.
Is it worth it? What is the difference between 24mm f/1.4L USM and 24mm f/1.
4L II USM?
Right now I am exchanging text with this guy... Need to make a decision to
buy it or not. He said excellent condition with UV filter and two caps.
Thanks in advance!! |

The Nikon 24mm f/2.8 AF-D is an excellent performer, and a fraction of the
size, weight and price of any zoom. It can replace both the 14-24mm and 24-
70mm zooms, saving you over $3,000 (and almost four pounds of baggage) with
improved performance. |
