三星5倍变焦摄像头今年到来 但Note10无缘

如果你仔细观察,会发现如今的智能手机拍照朝着越来越奇怪的方向发展了,那就是比谁拍得远。在主摄能够拍得足够出彩的情况下,想要在相机上面再做出一些新意已经非常困难了。但是办法总比问题多,想要继续在相机方面发展,所有的手机厂商都不约而同的选择了增加摄像头。到目前为止,公认最符合需求的多摄像头方案便是主摄+广角+长焦的组合。目前做得最好的除了拍月亮的华为P30 Pro便是OPPO Reno的十倍变焦版了。现在,三星也准备加入超长焦镜头的角逐,发布了5倍潜望式光学变焦手机镜头。

之所以称华为、OPPO、三星这些长焦镜头为超长焦,是因为目前市面上其他旗舰手机的普遍搭载的是2到3倍长焦镜头,而华为P30 Pro、OPPO Reno和三星新发布的这款镜头都达到了5倍变焦。很显然,要达到这样的级别,必须使用潜望式结构,所以上述几款镜头均是采用的潜望式结构。潜望式镜头的特点便是将镜头横放,手机镜头都为矩形而非普通的圆形,模块采用垂直堆叠的方式,主要是为了降低模组的厚度以便放入手机中。

再一个要解释的光学变焦其实也并非真正的变焦,大家其实要知道,手机上都是定焦镜头。手机上说的焦距其实也都是对于相机来说的等效焦距。相机的变焦是真正改变了镜头焦距的机械运动,而手机的变焦其实是在几颗不同焦距的摄像头之间切换而已。并且通常5倍变焦也只是指长焦镜头的等效焦距大约是广角镜头等效焦距的5倍,一般都不能达到主摄像头的5倍。因为广角镜头的等效焦距是最短的,长焦达到广角的5倍会容易一些。厂商宣传5倍变焦都是由于营销需要,至于几十倍的变焦更是营销需要,全都是在长焦镜头拍出来的画面中裁剪下来的,大家请理性看待。

回到此次三星发布的5倍变焦镜头,此技术是来自以色列相机技术公司Corephotonics,最早与OPPO展示5倍无损光学变焦的潜望结构相机解决方案便是来自此公司。大约在今年一月底,三星宣布将收购Corephotonics,现在距离收购大约两个多月,三星电机就发布了5倍变焦潜望式镜头。三星电机是从2003年就开始开发相机模块的,目前的成果是制造了世界上第一款带有图像稳定功能的双摄像头模块以及Galaxy S9首发的可变光圈模块。此次发布的5倍变焦镜头也只有5mm厚度,放进手机也基本不会突出。

从三星给出的样张来看,基本与目前的旗舰表现差不多,画面多倍放大之后画质并没有降低。重要的是以样张看来,三星的多摄像头组合表现还不错,广角、主摄和长焦的白平衡和调色没有特别明显的偏差。由于几颗镜头的素质不一样,要做到切换镜头之后的画面调色差不多,其实是很难的,目前的多摄手机都可以很明显看出换了镜头,三星如果能解决这个问题,其实也算一个提升。

最后便是这个5倍变焦镜头会何时上市的问题,目前的报道表示已经在量产了,将会在2019年下半年上市。并且在数码博主的爆料中来看,三星下半年的旗舰Galaxy Note10并不会搭载此款镜头。此镜头将会在三星下半年最具创意的三星智能手机上搭载。很显然,三星又会将初代的新技术放在中端机上试水,这也是三星一直以来的做风。

而对于市场来说,也许也是一件好事。三星电机做的镜头可并不只是提供给三星使用,三星本身也是非常大的供应链厂商,屏幕和内存颗粒方面已经取得了非常好的成绩,相机部门最近也开始发力,首发了6400万像素的镜头不说,又发布了5倍变焦镜头。要是以后能够大量供货给市场,那么说不定以后的手机只要肯花钱,随随便便都可以来个5倍变焦。届时,智能手机的拍照能力又将全部提高一个档次,我们拭目以待吧。
