一些尼康鏡頭 on D3X 和佳能鏡頭 on 5DMarkII 的 Resolution 調研

一些尼康鏡頭 on D3X 和佳能鏡頭 on 5DMarkII 的 Resolution 調研

尼康出了 D4 和 D800/D800E， 佳能出了 1Dx, 很快就要出 5D Mark III (or 5D X). 所以我想調研一下尼康和佳能鏡頭 Resolution。 這些調研圖的所有數據都來 自: http://www.photozone.de/reviews。這些數據幾乎全是在全幅上測的數據(尼 康鏡頭 on D3X 和佳能鏡頭 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. 這裏 resolution 的單位是用 (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. 詳細請看 (http://www.photozone.de/lens-test-faq) 。 注意: 這些調研圖的數據是"僅"來自一家 (photozone) 的數據. Resolution "僅"是 鏡頭的一個指標。大家做決定時要多看幾家評估和研究一下鏡頭的其它指標 (Distortions， Vignetting，Chromatic Aberrations， Bokeh， Flare 等)。 注解: 圖中 X 軸的單位是 F Stop, Y 軸的單位是 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. 轉軸鏡頭被下毒老手給抄熱。Canon 的這兩鏡頭都很好，配 5D Mark III (OR II) 應是絕配。我沒有找到 Nikon PCE (24mm, 85mm) 的數據。 鬱悶的是 (C80也提到 過): 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，鬱悶啊。詳細請看 http://www.kenrockwell. com/nikon/24mm-pc-e-compatibility.htm。
