后起之秀,索尼 G 大师镜头 FE 600mm F4 GM OSS 试用

2019-07-12
      一直以来,超远摄镜头都是相机厂商展示其最高光学技术和黑科技的 “舞台”,同时也是衡量一个影像系统是否完善、专业的重要指标之一。今年 6 月 11 日,索尼正式发布了全画幅超远摄定焦 G 大师镜头 FE 600mm F4 GM OSS。
作为索尼重磅级的长焦远摄定焦镜头,G 大师镜头 FE 600mm F4 GM OSS 包含了先进的光学和机械技术,在镜身重量、对焦、操控性及可靠性上都有很大的创新与提升,特别是配合上索尼全画幅微单™A9 及 A7 第三代机身时,可以最大程度发挥出该镜头的优异光学性能。而 105000 元的售价,也标示着它的目标群体是那些追求极致画质的专业级摄影师。
01. 索尼 G 大师镜头 FE 600mm F4 GM OSS
镜头外观
初次上手 FE 600mm F4 GM OSS 镜头,它的重量让人印象深刻,镜身仅重 3040 克,体积约为 163.6×449 毫米,在同规格的产品中,它有绝对的轻量化优势。在实拍的过程中,样片基本都是手持或者搭配独脚架完成拍摄,这也说明了该镜头具备出色的便携性和机动性。
而实现 FE 600mm F4 GM OSS 镜头轻量化的关键是,采用了与 FE 400mm F2.8 GM OSS 镜头类似的重心平衡设计,前端镜片的减少实现了镜头整体重心后移,让该镜头拥有良好的握持感,不会出现头重脚轻的现象,并且镜身还采用了镁合金材质,进一步减少了镜头的重量和体积。
在轻量化做到极致的同时, FE 600mm F4 GM OSS 在镜头可靠性和操控性上依旧延续了 G 大师镜头的优异表现。该镜头采用了坚固的镁合金机身和碳纤维遮光罩,可保证用户在恶劣天气和环境中的可靠拍摄。此外,为了减少镜头表面沾染灰尘和指纹,该镜头前组镜片还采用了氟化物涂层设计。
02. 索尼 G 大师镜头 FE 600mm F4 GM OSS 后端功能键分布
在操控性上,FE 600mm F4 GM OSS 带来了更为专业和便捷的设计,镜身前端有 4 个对焦保持按钮,可自定义部分菜单中的功能,镜身后端则分布了自动/手动对焦切换按钮、全时 DMF 对焦功能键及 3 种不同的光学防抖模式按键等功能。
实拍体验
除了专业的镜身设计外,在实拍的体验中,则让我真正感受到了 FE 600mm F4 GM OSS 镜头的成像魅力。
如图 03,你可以看到这只镜头在最大光圈 F4.0 的情况下,不仅中心区域成像非常锐利,而且画面边缘同样具备出色的分辨率。该镜头包含一枚 XA(超级非球面)镜片和 3 枚萤石镜片,可以最大程度减少画面的像差、色差和色散,从而提高画面的清晰度和对比度。
03. 最大光圈下,画面的边缘同样具备出色的分辨率,f/4.0,1/500 秒,ISO 160
值得一提的是,FE 600mm F4 GM OSS 所搭载的这枚 XA 镜片,是索尼目前开发尺寸最大的 XA 镜片,也是制作难度最高的镜片,在提供超高分辨率的同时也实现了柔美的背景虚化。如图 04,其焦外绿色草地如奶油般散开,色彩渐变自然均匀,并且和对焦主体的红鹮过渡自然,没有明显的硬线条和色块出现。此外,11 枚光圈叶片所营造的圆形光圈也有助于该镜头实现柔美的背景散焦效果。
04. 焦内成像锐利,焦外柔美,f/4.0,1/500 秒,ISO 200
而对于拍摄体育及野生动物等题材的摄影师来说,镜头光有精湛的影像画质是不够的,还需要快速、准确和安静的对焦。FE 600mm F4 GM OSS 配备了两个 XD 线性马达,搭配上索尼全画幅微单™A9 可以实现对拍摄物体快速地实时追踪对焦。
并且索尼还专门为该镜头的马达优化了对焦算法,可以较大限度的减少滞后和震动,基本可以实现无声的对焦操作,这利于摄影师抓拍体育赛事中快速移动的运动员或自然生态环境下的野生动物。
另外,摄影师如果需要用到更长焦段的话,可以开启全画幅微单™A9 的 APS-C/Super 35mm 功能,这样你的焦段就可以扩展至 900 毫米。或者使用索尼原厂的 SEL14TC 和 SEL20TC 增距镜,FE 600mm F4 GM OSS 安装上增倍镜后,焦段最长可扩展至 1200 毫米,并且仍可实现高分辨率的画质及快速、精准和安静的自动对焦性能。
05. 开启 APS-C/Super 35mm 后可获得更长的焦段,f/4.0,1/640 秒,ISO 500
06.f/5.6,1/800 秒,ISO 1000
总体感受  
FE 600mm F4 GM OSS 是第 10 支 G 大师镜头,集合了当前索尼所有的先进技术于一身,无论是在镜身设计,还是光学成像性能上,都给人留下了非常深刻的印象。尤其是在拍摄动态摄影时,用户基本不用担心画面失焦的问题,该镜头不仅拥有强大的对焦能力,还具备 3 种不同的光学防抖模式,可以为用户提供更多的创作可能。
总之,FE 600mm F4 GM OSS 作为 600 毫米焦段的后起之秀,一定会给你带来不一样的拍摄体验。
07.f/4.0,1/500 秒,ISO 600
08. 逆光拍摄样片,纳米 AR 镀膜可以减少逆光拍摄时产生的炫光和鬼影,f/5.6,1/800 秒,ISO 1000
09. 该镜头基本可以实现无声的对焦操作,不会干扰到拍摄对象,f/4,1/800 秒,ISO 320
