一些尼康镜头 on D3X 和佳能镜头 on 5DMarkII 的 Resolution 调研 |
|
尼康出了 D4 和 D800/D800E， 佳能出了 1Dx, 很快就要出 5D Mark III (or 5D X). 所以我想调研一下尼康和佳能镜头 Resolution。 这些调研图的所有数据都来 自: http://www.photozone.de/reviews。这些数据几乎全是在全幅上测的数据(尼 康镜头 on D3X 和佳能镜头 on 5DMarkII)。 D3X has 24.5-megapixel FX-format (35.9 x 24.0mm) CMOS sensor. 5DMarkII has 21.1-megapixel full-frame CMOS sensor. 这里 resolution 的单位是用 (LW/PH). LW/PH means "Line widths per picture height" - it's basically a unit for resolution (not sharpness which is a combination of contrast and resolution) limited by the max. resolution of the camera's image sensor. 详细请看 (http://www.photozone.de/lens-test-faq) 。 注意: 这些调研图的数据是"仅"来自一家 (photozone) 的数据. Resolution "仅"是 镜头的一个指标。大家做决定时要多看几家评估和研究一下镜头的其它指标 (Distortions， Vignetting，Chromatic Aberrations， Bokeh， Flare 等)。 注解: 图中 X 轴的单位是 F Stop, Y 轴的单位是 resolution (LW/PH). |

1. Nikon 24 mm F1.4 (Amazon $2400) and Canon 24 mm F1.4 L II ( $1614)

2。 Canon 24 mm TSE (BH $2089) and Canon 17 mm TSE. 转轴镜头被下毒老手给抄热。Canon 的这两镜头都很好，配 5D Mark III (OR II) 应是绝配。我没有找到 Nikon PCE (24mm, 85mm) 的数据。 郁闷的是 (C80也提到 过): The only Nikon camera with which the Nikon 24mm PC-E works properly is the D3 (Also D4). Even though the Nikon D300 is completely compatible electronically, the D300's flash gets in the way of some movements. The D700's flash overhangs even a little bit further than the D300's flash tested here, so the D700 will have the same, or more problems, than the D300. So the D800/D800E may have the same problem，郁闷啊。详细请看 http://www.kenrockwell. com/nikon/24mm-pc-e-compatibility.htm。
