索尼50mm f1.2的凭空出世实在是让人震惊,一举打破索尼FE卡口做不出1.2超大光圈镜头的传闻,也让索尼用户坚定了对这个系统的信心!这枚镜头的素质非常了得,根据镜头曲线来看,即使1.2全开就已经达到了极高标准,缩光圈后更是近乎直线,最为难能可贵的是,这款产品体积重量却并没有像其他家那么索大。它的滤镜直径为72mm,重量仅为778g,这对于原先是难以想象的。不过作为一款梦幻镜头,它的价格也不平易近人,来到了近15000元。
虽然很想要但这个价格确实难以下手,望了一眼手上的索尼55mm f1.8感觉还能再战几年。这枚镜头虽然不如50mm f1.2这枚强大,光圈仅有1.8但锐度也不遑多让,全开下就已经非常不错。它的滤镜直径是49mm,重量281g,使用与携带上完全没有负担。当然它也不是除了f1.8光圈不够大外全没有缺点,最近对焦距离过远,50GM的最近对焦距离0.4m,而55却到了0.5m。这使得它难以胜任近距离拍摄,也局限了使用场景,像拍摄一些美食什么的就很难受。另外,55的紫边效应非常严重,光圈全开下边缘部分容易出现紫色或是绿色的杂色,虽然在软件里可以方便的去处,但也容易造成出现灰色杂色线条。除此以外,我觉得55这款镜头除了没有绝佳的虚化外,真的可以算得上50GM的平替产品了!
人像拍摄方面这款镜头还是可圈可点的,虽然不如85 f1.4及50 f1.2那样有唯美的虚化,但它在半身人像或是肖像特写上还是拥有一定的虚化能力,当然全身人像的话就需要离背景远一些了。用这个镜头拍摄人像可以在一个适中的距离给出模特指示,适合需要带入一定场景的拍摄。
风景、小品拍摄的话比较考验构图能力,这款镜头属于标准视角要出彩比较困难,特别是拍摄一些室内的图像时,我个人建议采用竖构图能够带来更好的效果。

卢王咸3979拍摄风景用多大的光圈效果最好 -
褚杜呢17747887927 ______ 远近都清晰的大范围景观,一般多用8到11,长焦拍摄梯田等压缩效果的景观,用最大光圈,或缩一两档.
卢王咸3979拍摄人像时最好用什么光 -
褚杜呢17747887927 ______ 拍摄人像最常用的就逆光和侧光
卢王咸3979拍人像最好用多大光圈? 是越大越好吗? -
褚杜呢17747887927 ______ 光圈大,景深浅,容易得到虚化效果,突出重点.但也不是越大越好.要照顾镜头的性能,光线,拍摄对象,背景,还有焦距,快门,相机性能等.
卢王咸3979风光摄影与人像摄影在光圈设置上有何不同 -
褚杜呢17747887927 ______ 风光摄影使用镜头的最佳光圈,不同镜头不一样,一般是f/8-f/16之间的某一档. 人像摄影一般使用大光圈,在对质量要求不苛刻时使用最大光圈,质量要求较高时收缩1-2档.
卢王咸3979拍人像时用大光圈合适吗 -
褚杜呢17747887927 ______ 景深取决于三个因素:光圈、距离和焦距,三个因素都会影响景深.只有在很近的距离上,光圈才会对景深有效果,如果拍摄几十米以外的东西,F1.2和F16景深效果都是一样的.一般来说F1.2用来拍摄人像是有点过了,如果在5米之内,一定会是眼睛清楚但是鼻子模糊的这种效果.实用的人像光圈 在F2.8~F8之间,都可以取得满意的效果.如果兼顾背景的,那F11也可以用
卢王咸3979广角照人像,光圈多大合适? -
褚杜呢17747887927 ______ 广角拍人像不能离的太近,避免变形,所以人周围会留有空间,这个空间不如用景物来填充,拍成带景物的人像;一般f5.6左右即可,广角镜头大光圈时岐变比较严重建议不用.具体用多少光圈根据现场光.
卢王咸3979佳能的85mm f/1.8能拍大景深的风景照片吗? -
褚杜呢17747887927 ______ 85/1.8是极优秀的人像头,焦内锐利、焦外油润,被誉为没有红圈的L头.不要嫌定焦头麻烦,定焦头的成像质量是变焦头比不上的!烧到一定程度的色友都只烧定焦头.85/1.8当然也能用来拍风景,缩小光圈就行,F8以下景深就很大了,一般拍风景用F11左右清晰度就非常好了.此时快门会比较慢,最好上三脚架.不过要注意的是光圈也不是越小越好,太小的光圈会导致光的衍射现象加重,影响成像质量. 此外,中、长焦头不适合拍风景的说法其实是个误区,拍风景不一定非要广角头,广角、超广角由于构图范围太大其实并不容易驾驭.象城市风景、雪山顶峰、坝上风光等等很多都是中长焦镜头的杰作,你可以到色影无忌看看.
卢王咸3979光圈有什么用法和技巧 -
褚杜呢17747887927 ______ 1、光圈的主要作用不仅仅是控制曝光量,事实上,光圈最大的作用是控制景深:光圈越大,则景深越小,光圈越小,则景深越大. 2、最佳光圈(中等光圈)能够获得最好的锐度和分辨率,对定焦镜头再说,最佳光圈值一般为F4或F5.6;对变焦头来说,最佳光圈一般为F5.6或者F8;该类光圈值较适合人物、花卉特写、旅游纪念照等; 3、使用大光圈一般是在光线较弱时,例如傍晚或者室内;另外当需要把背景进行虚化和模糊时,比如人像、花卉摄影时光圈是越大越好; 4、使用小光圈主要是用于风景摄影,F11或者F16是常用的,它能使远近所有的景物都清晰的成像.
卢王咸3979拍风景和人像用什么镜头 -
褚杜呢17747887927 ______ 风景通常考虑用广角镜头,也就是焦段在35mm以下的,可以将更多的静物纳入镜头中;人像镜头通常考虑选大光圈、中长焦段的镜头,焦段以50mm、85mm、135mm最为经典.
卢王咸3979人像拍摄时光圈越大越好吗? -
褚杜呢17747887927 ______ 其实人像拍摄,一个简单有效的办法,就是把光圈开大,一方面可以通过虚化背景来突显人物,另一方面也能降低曝光时间,从而防止抖动.理由很简单:虽然大光圈对人像拍摄有利,但是拍摄时,光圈并不是越大越好.所以,对于镜头的光圈...
