佳能5D4配镜指南:还不知道怎么最给力?看过来!

<p style="margin-top: 20px; margin-bottom: 20px; height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;; word-break: break-all; color: rgb(0, 0, 0); width: auto !important;">新机的发布每次都让小编热血沸腾,(即便没有买上)也喜欢在预算内进行不同搭配。今年的明星单反佳能EOS 5D Mark IV 相当均衡,为这台相机配镜时,既不需要经历当年5D Mark III推出时的“镜头选择困难症”;也因为新一代“大三元”镜头陆续到来,旧镜头不能发挥机身的全部实力,重置镜头的需求愈加强烈。今天我们将从5D Mark IV的特性开始分析,看怎样配置镜头用得更合适,也更加有效率。</p><p style="margin-top: 20px;

height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;; word-break: break-all; color: rgb(0, 0, 0); width: auto !important;">  佳能5D Mark IV的推出,让佳能的中级全画幅数码单反的性能指标没有一味地跑数据,而是得到了更高层次的均衡,与此同时由于一部分镜头已经完成了升级换代,所以同样需求选择可以更加灵活。但也因为有需求上的差异,造成不同用户对镜头要求有清晰的分层,最终选择大相径庭。</p><p style="margin-top: 20px; margin-bottom: 20px; height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;;

margin-bottom: 20px; height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;; word-break: break-all; color: rgb(0, 0, 0); width: auto !important;">  佳能之前史无前例地在5Ds系列上使用5000万像素的CMOS传感器,让不少顶级135数码单反,甚至中画幅数码后背都感到压力。不过,这样的设定同样让佳能的镜头群倍感压力。因为传感器分辨能力的提升,需要更高的镜头分辨率,而部分定位中低端的镜头,未能完全发挥传感器实力。另外高像素传感器对读写速率要求更高,所以5D Mark IV为了权衡多个因素的需要,决定推出中间方案——也就是那块3040万像素,但这样也足足升级了一档,换来的不只是快。</p><p style="margin-top: 20px; margin-bottom: 20px; height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;; word-break: break-all; color: rgb(0, 0, 0); width: auto !important;"><strong>2、对比佳能5D Mark III:想要完全发挥先进对焦系统,选准镜头很重要</strong></p><p style="margin-top: 20px; margin-bottom: 20px; height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;; word-break: break-all; color: rgb(0, 0, 0);

margin-bottom: 20px; height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;; word-break: break-all; color: rgb(0, 0, 0); width: auto !important;">  回想一下之前的佳能5D Mark II,最让人诟病的是对焦系统,直到Mark III才开始改观。而在新款的5D Mark IV上,佳能非常“慷慨”地使用了顶级机型1D X Mark II的自动对焦系统,针对性地补上了前两代产品的不足,在三代的基础上改进了跟踪对焦的机制。同样的,相比5D Mark III最新一款在传感器像素上并没有非常大的提升,但是3040万像素相对于佳能的镜头来说明可以基本喂饱,正因为5D Mark III对镜头的要求仍然很高,但最近全新升级的镜头也能满足对应的需求。</p><p style="margin-top: 20px; margin-bottom: 20px; height: auto; overflow: visible; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 16px; line-height: 30px; font-family: &quot;Microsoft Yahei&quot;; word-break: break-all; color: rgb(0, 0, 0); width: auto !important;">  佳能5D Mark IV的对焦改进有两方面,光学取景方面,使用了全新的61点对焦系统,实时取景方面,全像素双核CMOS处理器的使用,提供全像素双核CMOS AF技术的相位差对焦。全新的技术让5D Mark IV的对焦性能有了一个全面的提升,这一点不容置疑。</p><p style="margin-top: 20px;
