对应全画幅相机的大光圈定焦镜头,一般分辨率都非常优秀,我们测试了佳能、尼康、索尼三个主流卡口适用的19款镜头,并选出了5个值得特别推荐的型号。全画幅镜头对任何制造商来说都是真正的挑战,对比APS-C画幅相机,全画幅传感器更大的传感器尺寸带来了更广的成像圈,因此就需要更大的镜头口径与之对应,镜头口径增大也同时会带来更严重的成像缺陷。不过好在对于定焦镜头来说,修正这样的缺陷并不是那么困难,因为定焦镜头没有变焦功能,要优化变焦镜头就必须将每个焦段的错误都进行纠正才
Corresponding to the full-frame camera aperture large fixed focus lens, the general resolution is very good, we tested the Canon, Nikon, Sony three mainstream bayonet lens for 19 and selected five models are particularly recommended. The full-frame lens is a real challenge for any manufacturer. Compared to the APS-C format camera, the full-size sensor’s larger sensor size results in a wider imaging circle and thus requires a larger lens diameter to correspond with , The increase of lens diameter will also bring more serious imaging defects. But fortunately for the fixed-focus lens, the correction of such defects is not so difficult, because the fixed-focus lens does not zoom function, to optimize the zoom lens must be corrected for each focal length errors
