  • 索尼A9可以说是集索尼最顶尖技术于一身的产品。得益于索尼半导体强大的研发实力,全新的全画幅堆栈式CMOS给A9带来了强大的性能表现。笔者通过2周的实际拍摄使用,对于它的最大感受就是快速和舒适。20张/秒的连拍很快,无黑屏和完全静音的拍摄与单反是完全不同的体验。只是相应的也带来了对存储卡更大的容量需求,出去拍摄一天居然快写满了2张128GB的卡,启用的仅仅是JPG格式!A9仅仅卡槽1支持UHS-II高速卡有些遗憾。拍摄完之后上万张照片的挑选工作也要花费很长一段时间,不过这也是个甜蜜的负担吧。693点相位对焦...

  • Abstract:  最近有一些声音说索尼全画幅微单A9会有过热现象,最近索尼又发布了Ver1.01的固件,对A9过热警告的规格进行了修正。现在过热的消息主要来自于That1CameraGuy的测试,一开始说是的是连拍时会过热关机。后来又测试了新的Ver1.01固件, “自动关机温度”这个选项设定为“标准”,10几分钟不管哪个固件还是会照样关机。当然也有不同的声音,比如Ron Simon和Theoria Apophasis。Ron Simon的测试结果表示Ver1.01固件在户外连续拍了两个小时也没有出现过热现象,Theori...

  • 从前文两个大项目测试来看,索尼A9的画质特点非常鲜明,长项是高感抑噪,而短板是宽容度,之所以如此,想来索尼也是根据适用人群来定的,A9主要针对新闻、体育、野生动物等题材拍摄,而对于这些题材摄影师来说,最重要的是高感画质、追焦性能、连拍速度、可靠性,至于宽容度、分辨率(像素)够用就好。业界典型的例子就是尼康D5,其定位与A9类似,同样属于偏重高感,而宽容度不算好的产品。如果你是一个注重低感光宽容度、长曝画质的用户,那么显然A9并不是你的菜。...

  • 进步很大仍有遗憾必须要承认,索尼A9确实是索尼近两年憋出来的“最大的大招儿”,野心也是不言而喻的向以往被旗舰级全画幅数码单反相机“垄断”的体育、新闻和生态等领域发起进攻,通过日益进步的电子技术突破了反光镜箱+焦平面快门这一系统在对焦和连拍的“封印”,高速连拍时的显示效果也不再会出现单反相机的黑屏、微单/无反相机的延迟,如果不是“模拟”的快门声和闪烁的屏幕,我都很难察觉索尼A9正处在每秒20张的高速连拍状态,第一次实拍体验这款产品时着实给我了非常大的震撼,也颠覆了以往对于高速连拍的体验。这大概是有史以来最强...

  • Abstract:  一直以来在器材界都有个不成文的规矩,只有拥有顶级体育旗舰机的厂商才是这个行业的龙头企业,其专业标杆作用不容忽视。近年来,索尼微单相机在全画幅市场上走得顺风顺水,进军体育界是迟早的事。2017年4月19日,又是一个值得载入相机发展史册的日子,索尼还是老样子没有改变深夜发布新品“毛病”,但这次的主角绝对让你兴奋的睡不着觉——新一代全画幅微单A9正式亮相。然而要打造直接对抗佳能EOS-1D X Mark II、尼康D5的旗舰产品绝非易事。一直以来无反系统进军体育摄影,都存在诸多技术难点:追焦性能、连拍速度、续航...

  • 对于关注摄影器材的人来说,大家都清楚,无反相机是相机未来的必然发展方向。当然,市场的反应总是滞后一些的,微单真正要谈取代单反还有很长的路要走。而消费者的困惑在于,究竟现在的微单能否满足职业摄影师的拍摄要求。  从A7RII开始,其实索尼微单已经俘获了大量的职业摄影师。风光摄影、建筑摄影、人文旅游摄影,大多数从单反转到微单的职业摄影师都会选择索尼A7RII。同时A7SII也满足了许多视频工作者的工作需要。单反只剩下最后一个看似牢不可破的阵地--体育拍摄市场。  索尼全画幅A9的发布,目前看,可以说是成功...

  • Abstract:  【IT168 评测】为了进一步测试 索尼 A9的最终成像效果,我们来到了北京著名的白塔寺附近,进行了为期半天的室外人像拍摄。首先触动到笔者的,并非是画质,而是 索尼 A9的测光。通常使用各家的矩阵测光、区域测光(说白了就是智能测光)时,在拍摄人像时,机器都无法针对性的对拍摄人像进行智能补偿。按通常的习惯,使用智能测光拍摄人像往往是需要我们手动增加半档到一档的曝光补偿的。但是使用索尼A9的多重测光模式时,就完全不需要进行补偿。测光准到哪怕再手动增加三分之一档,照片就会过爆。在这一点上,由于是微单是全像素参与...
