  • Abstract:  作为一名新闻纪实摄影师,对于器材的要求非常的高,首先是轻巧便携,其次是要非常快速的反应能力,比如快速开机响应,精准快速的对焦能力,再有就是连拍速度也要够快,这样才能抓住每一个稍纵即逝的精彩瞬间。当我拿到索尼全画幅微单旗舰A9之后,被他强大的性能瞬间折服,这是一台几乎没有任何短板的旗舰级产品,对于拍摄新闻纪实题材来说也是完全可以胜任,我意识到这可能就是我一直在寻找的一台相机。新闻摄影首要是“快”,但我也追求好的“画质”,但以前的相机并不能提供给我们选择空间,在传统意义上“快”与“画质”是有点冲突的。如果能够...

  • ,相信你看完后,心中就会有一个明确的答案了。索尼全画幅微单A9 VS 尼康全画幅单反D5外观设计外型上是一目了然,索尼A9在尼康D5面前简直小鸟依人,轻便机身在长时间拍摄中可让用户减轻很多负担。不过A9虽然身小,但功能齐全,该有的都有,包括只有专业顶级设备才有的LAN接口。A9的双卡槽设计也是微单用户一直所期待的。画质画质方面,索尼A9和尼康D5不愧都是顶级的设备,除了JPG直出的色彩有不同偏向外,画质和解析力上完全不用担心。其实这里索尼A9有个小小的优势,其电子取景器能所见即所得,EVF中显示的画面与你...

  • Abstract:  我是一名美国国家地理杂志的摄影师,为这本杂志拍摄已经超过了30年。作为一位国家地理摄影师,我会拍摄非常广泛的题材,从人物到风光,再到静物等各个题材都会涉及,而这对于相机的要求是很高的,成像质量、反应速度、专业的操控、稳定性等各个方面都要达到行业最高水准才能满足我的需要,这台索尼全画幅微单旗舰A9就是我所需要的全能相机。在几十年的拍摄期间,我去过世界上很多地方,在这些地方里,北京是比较特别的。古香古色的青瓦红墙、安逸宁静的北京胡同,以及北京人开放豁达精神,这些都给我留下了深刻的印象,所以我经常来到北京,这里...

  • JPG高感降噪算法较好, 相位检测点,覆盖范围大,多点追踪性能明显提高, fps无黑屏连拍,能捕捉更为细微的动作, 支持双转盘、摇杆、AF-ON、触控选焦点,操控更为专业, 翻转屏和取景器分辨率更高,取景器延迟更低, 电池续航能力明显提升,优于A列, 支持超清视频、支持ps慢动作视频拍摄, 支持机身五轴防抖,可与镜头防抖协同工作, 电子快门下,果冻现象明显减轻,
  • 障碍物对焦稳定性有待提高
  • 究是有极限的,以佳能为例,每代连拍速度提高一两张已经颇为不易,未来随着濒临极限迟早会放弃发展。索尼的A9给我们看到了未来,依托电子技术显然发展更为迅猛。单就索尼A9这款产品本身,超高速连拍、静音拍摄、机震轻微、对焦覆盖大、区域多点追踪等都是优势,然而之所以说A9只是革命的开端,那是因为目前无反系统还不足以彻底碾压单反,比如障碍追焦稳定性、续航能力、机身可靠性、相机写入时无法操作、电子快门抗光源频闪、续航一般等问题。未来相信经过两三代的改进,这些都可通过技术手段一一解决,直到攻下体育机这座最后的堡垒,才能宣...

  • Abstract:  在胶片相机时代,不论哪一家相机厂商,都不用关心传感材料对相机的影响,更在意的是机械结构、光学结构甚至于操控感受的进步与比拼。但在数码时代,CMOS的集成度越来越高,传感器不仅仅承担着光电转换、捕捉画面的任务,连相位对焦、测光甚至景深合成等功能也被集成在了CMOS上。近年来,数码相机市场中各个品牌的角力结果已经陆现端倪,拥有自研、自产、自销CMOS能力的厂商才有在这个市场中博弈的最大筹码,而如果自己丧失了CMOS设计、研发、生产的能力,数码相机中最重要的传感器部分,就要仰人鼻息,发展受困。索尼在连年破产的谣...

  • Abstract:  这是我第一次采用索尼微单深入非洲进行创作,它就是看参数就让人兴奋不已的索尼全画幅微单™旗舰A9,搭配的则是索尼G大师镜头FE 100-400mm F4.5-5.6 GM OSS。拿到A9的第一印象是在体积和重量上占据极大优势,相比其他单反而言非常轻巧,更加便携带,在拍摄时亦能做到迅速的移动,这是其他单反所无法比拟的。Sony A9;FE 100-400mm F4.5-5.6 GM OSS;1/400s;F4.5;ISO 160索尼全画幅微单旗舰A9的连拍速度非常让人吃惊,凭借内置堆栈式CMOS,达到了20...

  • 总得来说,索尼这次强调A9是微单全画幅旗舰底气是非常踏实的,虽然A7系列已经有了不错的表现,甚至许多人已经把A7RⅡ抬上了135相机旗舰阵营,但是索尼E卡口全画幅机身,真正的旗舰或者说End级机身,还是非A9莫属,当然索尼一贯的把9字头留给A9也是非常简单、明了、直观的信息。综合对焦、连拍、分辨率、动态范围、高感表现、操控手感,A9的均衡性比A7系列的任意一款机身都要高,而且在对焦、连拍、高感表现、动态范围有着非常突出的表现,这也是数码单反End级机身最突出的性能。虽然我本人对体育、新闻等高速摄影不感兴趣...

  • 本文来自色影无忌一直以来体育摄影领域旗舰单反都占据主导地位,然而在今年似乎出现了一点点变化,索尼发布速度旗舰微单A9。A9凭借内置堆栈式CMOS,支持20张1.2L II USM尼康D5+AF 85mm f矩阵测光、自定义白平衡、焦距85mm、光圈fN相比不偏科无短板,未来重点应放在远摄镜头群建设和追焦性能改善上。...

  • 从前文两大测试我们可以看到三款相机都是针对体育摄影优化,长项是高感画质,宽容度放到全幅相机序列中只能算中等偏下的水平。然而文无第一武无第二,高感测试中尼康D5可以说是顶尖之中的顶尖;而在宽容度测试中,虽说是此类机型的短板,但佳能1DX2的表现令人印象深刻,一改以往对佳能的印象,可以说佳能从1DX2、5D4、80D这代开始加强宽容度表现;索尼A9的堆栈式传感器展现了半导体技术的先进性,画质方面表现全面,与C/N相比不偏科无短板,未来重点应放在远摄镜头群建设和追焦性能改善上。...

  • 从外观上来说,索尼全画幅微单A9虽然整体风格大小与A7系列并没有太大区别,但在一些按键细节以及整体的操控性上来说,毫无疑问A9更具专业相机该有的水准。12345下一页...
