瑞典《摄影》杂志镜头测试报告精选
瑞典摄影杂志“FOTO”（其前身名为“Aktuell
Fotografi”）的镜头测试报告系列是比较著名的，它是于哈苏的一个光学实验室内进行的。它的测试结果采用图表式说明，这里我们将其整理并转换为数字形式。
这些数值代表被测镜头分辨率为20lp/mm时的MTF百分比数值。MTF数值测试用投影黑白线条的标板进行，测量其反差对比值。如果影像的反差对比度完全等同于标板，则测试数值为100%，但这是理论值，事实上是不可能达到的。当反差对比值降为一半时，测试数值为50%。测试数值为零代表反差对比完全损失，标板上的黑白线条被还原为一片纯灰色。测试数值高于80表明像质极佳，低于30则在普通扩印的小幅照片下仍能察觉像质较差。
测试分为径向光线和切向光线两个方向进行，“/”符号两边的数值分别代表它们的测试数值，如果两边的数值相差较大，表明镜头的像散现象较严重。
镜头名称后扩号内的数值分别表示测量的实际焦长和影像边缘的畸变程度，负值代表桶型畸变，正值代表枕型畸变。从影像中心到最边缘的距离为21.6mm，如果畸变为-5%，可理解为影像最上部的水平线条向内弯曲，在边缘部的弯曲度为1.08mm。
每一行列有三对MTF数值，分别取自中心，离中心9mm，离中心18mm处。例：
Canon EF 28-105/3.5-4.5 USM (29-102mm/ -4.7%,
+2.5%, +4.3%)
28mm, f/3.5: 56/58, 51/43, 32/21
28mm, f/8: 80/82, 82/62, 74/40
50mm, f/4: 63/67, 63/64, 47/19
50mm, f/8: 81/83, 81/77, 79/65
105mm, f/4.5: 72/72, 69/61, 62/38
105mm, f/8: 80/83, 80/74, 72/35
该镜头实际焦长范围比标定的小，28mm处有明显的桶型畸变而105mm处有明显的枕型畸变（变焦镜头的畸变通常比定焦镜头大）。28mm处全开光圈时，边缘成像水平比中央低。50mm处全开光圈时，边缘像散严重（47和19相差悬殊）。而总体上讲，这是一支很不错的镜头。
