本人新手入门，无奈人傻钱少，入手了A7R3+FE55 1.8+24-105 F4之后。缺手痒不止，垂涎腹肌的胶片模式，固在某鱼淘了二手的XT20  XC15-45套机。可是无奈XC15-45手感做工实在令人叹息，又忍不住入了XF23 F2。然后有了下记的无聊测试，参数以图片显示为准，仅供娱乐

确实，俺的232大光圈也不锐，收点光圈会改善点

哈哈，真逗

我有23 2.0 所以你骗不了我。

价格倒是不算，要不是标的这么高的价格也就是R3的套头而已，说实话用了XF18-55以后已经想把它出掉了，太大太重。拍照片也不是为了数毛的。

矮油，是马甲就是马甲嘛！无忌论坛规则也允许注册多个笔名，我就有N多个马甲啊，用不着这么神经质吧？

另外，大法的FE24-105 F4不属于低端变焦头吧？

又不干鸡鸣狗盗之事，要马甲何用。一个是手机端微信认证的ID，一个是电脑端。都是自己的相机，随便娱乐大众，你这么问的意图又是什么？ 本帖最后由 solution_tm 于 2019-3-5 13:29 编辑

这位不知道是常道ID是你的马甲？

那就对了啊，锐度到了F4这颗镜头有了很大的变化，可惜把适马的S30 1.4出了，不然可以比较一下，拼印象同样适马1.4的锐度可以优于XF23的F2。
大法的变焦我是说24-105 F4,但是xf23是残幅所以F2的光圈转换成全画幅是有个折算的=F3.5,因此这样比较的话中心锐度肯定是有差距的。

请问，不敌大法的哪个低端变焦头？下图是lenstip.com测试的XF23 F2镜头分辨率：



The situation in the frame centre is very nice indeed. What’s important, images are useful already from the maximum relative aperture with MTFs reaching over 48 lpmm. The highest results the lens produces by f/4.0 – f/5.6 with resolution values hovering near 73-74 lpmm. It is a level worth a good fixed focus device and, what’s interesting, higher than that of its faster 1.4/23 brother which was able to exceed just 70 lpmm.

Still small dimensions of the lens influenced its performance on the edge of the frame and here the slower Fujinon is definitely weaker than the faster one. The maximum MTF values of the tested model barely exceeded 51 lpmm; those of the faster lens reached 55 lpmm. Still the overall situation is not bad at all. The quality of the image can be criticized only at the maximum relative aperture; on stopping down the aperture to f/2.8 the image becomes completely useful.

At the end of that chapter traditionally we present crops taken from photos of our resolution testing chart which were saved as JPEG files along with RAW files used for our analysis above.

下面的是Sony Carl Zeiss Sonnar T* FE 35 mm f/2.8 ZA测试结果：



You shouldn’t expect any record-breaking values from a lens constructed with preserving small dimensions in mind, and, accordingly, there are no records here. Still it is important that already at the maximum relative aperture the Sonnar provides useful images, with the MTFs exceeding 50 lpmm. The maximum of its possibilities it reaches by f/4.0, getting to 62 lpmm. That result is several lpmm short of the best primes but, overall, you can’t have any reservations whatsoever concerning the image quality in the frame centre.

The physical dimensions of elements amounting to just more than a dozen millimeters along with a significant distance from a large, full frame sensor, made us worry about the image quality on the edge of the frame. The measurements show those fears were more than justified. The image quality on the edge of the APS-C sensor is barely on the borderline of the decency level; on full frame the lens never reaches that level at all, with results only exceeding 30 lpmm. It wouldn’t be a good result even on the 21-24 megapixel full frame sensors of Canon or Nikon cameras, used by us so far for testing full frame lenses…

To sum up the tested lens did its job well in the frame centre but on the edges of full frame it performed a bit weaker than expected.

At the end of this chapter traditionally we present crops of our resolution testing chart, taken from JPEG files which were saved along RAW files used for the analysis above. 本帖最后由 来者犹可追 于 2019-3-5 11:26 编辑

富士这两张照片明显过曝了！同场景对比，请设置同样的曝光参数来对比，否则没有说服力

232不适合大光圈近拍，可以百度一下

让我受刺激的是xf23全开2.0锐度居然崩了，虽然对一个等效35㎜的镜头来说也无碍。但是画质居然不敌大法的低端变焦头，也有点说不过去。套头15-45倒是有惊喜。
