索尼ES系列新军_DVP_NS9100ESDVD_SACD播放机
索尼ES 系列新军———DVP- NS9100ES DVD/SACD 播放机□ 华 生图 1 NS9100ES 的正面图 2 NS9100ES 的背面索尼的ES 系列产品素来是发烧友心 目 中 的 名 器 。
所 谓ES ( El evat ed St an-dar d ) 是指采用先进的电路、讲究的用 料、一流的工艺和精湛的设计开发出来的 功 能 全 面 、 质 量 优 异 的 系 列 影 音 器 材, D V P- N S91 00ES 就是其中的一款高档 D V D /SAC D 播放机。
目前 市 面 上 普 通D V D 机 只 要 几 百 元 串扰, 进一步提高音频信号的纯净度; 在工艺上, 采用四层印制板设计,使走线更合理, 信号更纯净。
综观以上特色, 另一个问题是: 不少发烧友愿意为之解囊。
在前程似锦的蓝光影碟机向我们走来之际, 购买即将一 台 , 但 91 00ES 却 要 1 0000 元 的 高 价 。
高价往往有其高价的理由, 拿91 00E S 来 说, 索尼采取了一系列的技术措施来提 高 播 放 的 素 质 和 效 果 : 在 视 频 性 能 方 面, 索尼采用1 4bi t /21 6M Hz 的视频数模 变 换 器 来 提 高 图 像 质 量 , 并 用 Si l i con I m ages 的芯片来实施普通分辨率碟片提 升至720p 和1 080i 的 高 清 画 面 输 出 ; 用H DM I 端子来简化数字A V 信号传送, 高信噪比, 确保优良的音视频素质; 采 提 在 音 频 性 能 方 面 , 采 用 i .Li nk ( 即 I EEE 1 394) 数字连线, 无失真传送D SD 音 频 和SA CD 的 高 音质 音 频 信 号 , 配 有i .Li nk 的AV 放大器作宽带解码。
采用双向传输 流量控制协议消除以往高质量数字音频 传输过程中出现的声音不稳定现象, 有 效地降低了失真并提高了音频信号的清 晰度; 在电路设计上, 采用两只环牛分 别为模拟电路和数字电路供电, 以减少图 3 NS9100ES 的内部图 5 NS9100ES 的内部图 4 NS9100ES 的内部图 6 NS9100ES 的遥控器过时的高价91 00E S 岂不是有点失策?其实不能这么简单地看问题: 一方面是蓝光播放机目前虽然发展得红红火火, 但还有其自身尚未解决的问题; 再说, 索尼自己就在力推蓝光格式, 用91 00ES 来否定蓝光碟 机岂不是自己打自己的耳光? 索尼认为目前 仍有必要推出其91 00ES 来填补这段空白的理由; 另一方面, 蓝光软件尚不丰富, 而D V D 和SA CD 两种碟片发烧友都有一大堆, 如何利用好 这 些 碟 片 才 是 当 前 的 首 要 任 务 。

SONY摄像机行水货鉴别
谨防购买索尼刷号假货!不看轻松骗你几百还没保修！版主置顶什么是刷号机？对于“刷号机”的概念，我们在过去曾经多次谈到，简单的说，刷号机其实就是水货。
一些不法JS在拿到水货产品后，将机器取出，用仿制的行货包装、机身号、保修卡、说明书、配件等产品对其重新进行组装，于是原本的水货摇身一变，成为了“行货”。
非太平洋网图片，内容及服务网络与本站无关刷号机能保修吗？刷号机外包装与行货相似度极高，所以消费者很难将刷号机分辨出来，但实际上这仍然是一种水货，在大多数厂商的售后部门是可以被鉴定出来的，因为并非正规渠道的产品，所以一般都不会享受到的质保服务。
摄像机也有刷号机吗？刷号机不单是数码相机的专利，在数码摄像机中同样存在着这样的情况。
尤其是最近，多数索尼DV都出现了刷号机产品，比如索尼62E、82E以及光盘式的708E、808E等等，都有这种货的存在，大家在购买中要特别小心。
消费者可以说，刷号机最直接危害的，就是消费者的利益。
花行货的钱买刷号机刷号机本身就是水货，所以价格上面的优势比较大。
单纯从经济的角度来讲，这并非什么坏事。
但值得注意的是，由于普通消费者很难辨别出刷号机与行货的区别，不少无良JS将刷号机当作行货甚至更高的价格来卖，消费者多花了钱，反而买不到行货产品。
质保质保是刷号机最大的软肋，如今索尼客户服务中心已经可以鉴别出行货与刷号机的区别，所以刷号机一般来说是得不到正规的质保的。
一旦消费者手中的机器出了问题，最好的情况也就是当作质保期外的产品，进行收费维修。
经销商既然市场上有了便宜的刷号机，行货产品的销售必然受到影响。
虽然大多数JS都会去接受刷号机，但一些有良知、仅仅销售正规行货的经销商，销售必然会受到刷号机的打击。
换个角度想想，其实谁不想稳稳当当的赚钱呢？即使是黑心JS，在销售刷号机的时候，也难免会心虚，至于那些本来卖行货就可以盈利的经销商，现在利润不变，却要担着刷号机无法质保的风险，同样也是一种损失。
四招教你辨别索尼假行货手机
四招教你辨别索尼假行货手机淘宝网现在很多商家打着金牌卖家的幌子卖假行货手机，最普遍的作法就是将行货手机信息拷贝到水货手机中，包括芯片信息、手机内信息贴、入网许可证等。
需要说明的是，他们并不是随便拷贝的，都是以刚卖出不久的行货手机信息进行拷贝，因为索尼行货都有销售记录的，就是登记所销售手机（根据imei等信息）销售时间，这样能骗过索尼售后，一般来说，如果发票开具时间和索尼售后查询到的销售时间不是同一天，那就是假行货。
下面说下具体的辨别方法：第一招，对比外包装。
当你在淘宝购得所谓行货手机的时候，可以拿着外包装盒到索尼专卖店进行对比，目前假行货的包装盒与真行货在尺寸颜色方面略有差别，但还是能看出来，当然，如果卖家用真盒子来装假行货就看不出来了，这就该看盒子上的imei条形码了。
现在淘宝网卖的假行货手机的imei条形码和真行货是有明显区别的，一是条形码的长度，二是印刷字体，差别很大，与真货对比谁都能辨认出来。
第二招，网上看imei查询真伪的记录。
如果你想去工信部或者让索尼售后查imei真伪，那我劝你别费劲了，拷贝真机的信息怎么会是假的？我劝你去/查，注意，并不是看imei号是不是真的，而是看你之前有没有查询过，一般情况下，行货手机是不会有人在你之前查的，应该出现下面画面，注意来自哪里的查询和最后那个红色数字。
如果查询结果有很多条，那就说明是假的，尤其是来自很多地方的查询。
第三招，去索尼客服刷系统。
如果以上两招没有问题，那么基本可以恭喜你买到真行货了，如果你还不放心，那就到索尼客服说自己手机系统有问题，请他们给你重新装系统或者升级，由于假的行货手机对芯片信息或者硬件进行了更改，接上官方程序后会提示硬件识别错误或者手机直接不能开机，按开机键会出现一个大三角形，里面有个叹号。
第四招，返厂检测。
这是针对第三招的，如果出现了问题，索尼客服一般会建议你返厂检测的，这时你有两个选择，一是直接对卖家说手机有问题，要求退货（不要选择换货，不可能给你真的），如果卖家不见棺材不落泪，你就选择返厂。

索尼VAIOVGN_FW19_B试用手记老七的7个瞬间
索尼VAIO VGN-FW19/B试用手记老七的7个瞬间干摄影工作室这行，平时拍摄的活儿很忙，没太多时间用电脑，不过索尼这款笔记本电脑FW19/B却给我的工作生活带来了相当多的快乐。
针对影音优化的配置，双读卡器插槽，一键启动PS，蓝光刻录，所有这些似乎是给我一个人设计的。
应《数码摄影》之约，在朝阳公园搞外拍时，是我第一次把这款笔记本带出去。
一上午的拍摄，笔记本都是让助手背着，虽然辛苦点，但是用笔记本的16.4英寸炫彩贵丽屏回放照片，可以让我更安心。
虽说现在数码相机的屏幕已经很不错了，最高到了3.5英寸92万像素，可是跟FW19/B 的16.4英寸16：9宽屏比，还是有天壤之别的差距。
在中午的拍摄间隙，我、模特、助手一起围坐在长桌旁，欣赏半天的劳动成果，很是惬意。
FW19/B 自带读卡器可以直接读取存储卡信息。
虽然我不关心其中的原理，但是相对我以前的笔记本，这款产品的色彩表现非常出色，艳丽、明亮，尤其是红色的饱和度表现尤其让我满意。
FW19/B 采用的新一代炫彩贵丽屏通过改良色彩过滤器与光源的协调性，提高色彩纯度，色彩还原更为明亮、更为鲜艳。
在XBRITE-HiColor 技术的帮助下，FW19/B 的屏幕色彩还原效果比之前FZ 系列的92% NTSC 色域屏幕表现更好，不仅实测对比度达到420:1，而且色彩均匀性和还原性表现更佳。
此外，FW19/B 机身前面配有的SD 卡、MS 记忆棒读卡器，可以直接读取存储卡数据，受到摄影师和影友的喜爱。
为客户做活儿，经常会处理大量的RAW格式照片，数据量非常可观。
FW19/B 可以很快速地完成RAW 原始数据的批处理工作。
尼康D700的NEF 格式文件每张就是11MB 大小，原来的电脑处理起来很困难，而FW19/B 似乎显得很轻松。
我用尼康Capture NX2大约不到1分钟的时间就处理的10张NEF 格式图片。
而用Photoshop CS3的速度也相当快，打开10张D700拍摄的JPG 格式照片仅仅用了15秒钟。

Improved Image QualityThe new CMOS image sensor and BIONZ XR™ image processing engine in the Alpha 7S III delivers legendary S-series sensitivity with significantly enhanced color reproduction and texture renderings for improved overall image quality. The base ISO has been lowered to 80, resulting in a normal range of 80-102,400 (expandable to 80-409,600 for video and 40-409,600 for stills) to provide more flexible ISO plus wide dynamic range with low noise at all settings. It offers improved image quality by approximately 1 stop of noise reduction in the middle and high sensitivity ranges.The colors and textures of foliage, human skin, and more are ideally and consistently reproduced without dependence on light sources. Gradation rendering has also been refined for better looking skin tones and highlight roll-off in portraits. It also improves AWB (Auto White Balance) performance with a new “Visible light + IR Sensor” that helps to achieve more precise white balance under artificial lighting, including fluorescent and LED lights.Versatile OperabilityAdvanced Autofocus Performance for Hybrid useFor the first time in an Alpha 7S series camera, the Alpha 7S III offers Fast Hybrid AF by combining phase-detection and contrast-detection AF, giving it the ability to track subjects over a wide area with outstanding speed, precision and smoothness, even when using a narrow depth of field. Fine focus expression is possible with Sony’s E-mount lenses.For environments with a lot of movement, Real-time Tracking and Real-time Eye AF are available to maintain constant focus on the intended subject. Sony’s advanced Real-time Eye AF improves detection performance by 30% over the previous system, thanks to the new image processing engine. It ensures accurate, reliable detection, even when th e subject’s face looks away. Real-time Tracking is initiated simply by touching the subject on the screen. Real-time Eye AF is automatically initiated when an eye is detected.Flexible Autofocus Settings for Movie ShootingBased on customer feedback, the camera includes several AF features for professional users including AF Transition Speed in seven settings, to easily create rack-focus transitions, and five AF Subject Shift Sensitivity settings, which allows the user to customize how easily AF will switch or stay with the locked-on subject. Touch Tracking allows user to not only initiate Real-time Tracking, but also compose and shoot while using a gimbal or while shooting solo. It’s now possible to Touch Focus during manual focus mode on the LCD screen or remotely from the Imaging Edge Mobile application17.New Heat-dissipating StructureThe Alpha 7S III’s design has been updated to ensure effective heat dissipation and minimizes overheating — even during extended continuous recording sessions at 4K 60p 10-bit 4:2:2 video lasting an hour or more88. A newly developed unique heat dissipating structure keeps the image sensor and image processing engine temperatures within their normal operating ranges, preventing overheating while maintaining compact body dimensions. The new heat-dissipating structure requires no fan or cabinet vents allowing Alpha 7S III to maintain dust and moisture resistance18.Movie Assist FunctionsFor video on-the-go, the Alpha 7S III is the first Alpha series camera to include Active Mode9 with 5-axis optical in-body image stabilization to support especially difficult handheld movie shooting. It is also the first Alpha series E-mount body to feature a side-opening vari-angle rear screen, perfect for gimbal-mounted shots, complicated angles, handheld operation and more. The screen rotates sideways, up and down, and features a 3.0 type 1.44 million-dot (approx.) touch panel LCD monitor, for optimal visibility even in bright outdoor environments.In addition, the Alpha 7S III provides a selection of new Creative Look with 10 presets that can be used for both photo and video shoots, making it easy to create interesting moods right in the camera to be used as is or customized by the user.A digital audio interface has been added to the camera’s Multi Interface (MI) Shoe for clearer audio recordings from a compatible Sony external m icrophone. Used with Sony’s XLR-K3M XLR Adaptor Kit, the Alpha 7S III provides 4-channel 24-bit digital audio recording capability in an Alpha series camera for the first time. Like other MI shoe accessories, no cables or batteries are required, providing unrestrained freedom for Alpha system moviemaking.Additional movie assist functions include a redesigned monitor display with a bold, clearly visible red frame that makes it clear when recording is in progress even when mounted on a rig or gimbal, custom zoom settings, adjustable white balance while recording, display rotation, interval recording, still extraction from movies and more.Captured by A7S III with SEL2470GMOutstanding Still Image PhotographyThe Alpha 7S III includes a fast Hybrid AF system with 759 phase-detection AF points covering 92% of the image sensor. The camera can also achieve high AF precision to accurately and reliably focus in light down to EV-619, where subjects are difficult to see clearly even with the naked eye. Users can continuously shoot more than 1,000 uncompressed RAW12images at up to 10fps, or up to 8fps in live view mode, with either the mechanical or electronic shutter.The Alpha 7S III also includes the world’s first 9.44 million-dot (approx.), 0.64 type Quad-XGA electronic viewfinder with a high-definition OLED display and refined. The Alpha 7S III viewfinder offers a 0.90x viewfinder magnification20, 41° diagonal field of view, 25mm high eyepoint for clear, low-distortion corner to corner viewing. It is also dust, fog and moisture resistant, extremely responsive, and has switchable modes for different subject types. Every aspect of the Alpha 7S III viewfinder has been designed and refined for a professional workflow.For the first time in one of Sony’s digital cameras, the Alpha 7S III includes HEIF (High Efficiency Image File Format) allowing for smooth 10-bit gradations and advanced compression technology to maintain image quality while significantly reducing file size and saving storage space. HEIF stills shot in this mode can be played back on a compatible SonyHDR (HLG) TV via a direct HDMI Type-A connection from the Alpha 7S III, delivering true-to-life dynamic range21.Versatile Design Made for the ProsCFexpress Type A for High-speed Data TransferIn another world’s first, the Alpha 7S III features two CFexpress Type A compatible media slots which also support UHS-I and UHS-II SDXC/SDHC cards, enabling high write-and-read speeds while keeping the camera body compact in size. CFexpress Type A cards are ideally suited to high-speed continuous RAW still image shooting as well as 4K 120p movie recording at high bit rates22, providing next-generation write speeds that can quickly clear the buffers of cameras that generate high volumes of still image and movie data. High-speed data transfer to a PC is possible at about 1.7 times faster23 than that of SD card. The dual slots can be set to relay mode for extended continuous recording of even the highest bit rate data as well as simultaneous recording and sort by format type recording.Revised Menu System with Enhanced Touch ScreenThe Alpha 7S III also features a revised menu structure for easier navigation and touch-responsive menu operation for faster, more intuitive control. For creators who shoot both stills and movies, separate settings can now be stored for stills and movie shooting for quick transition between the two.High Reliability Gives Creators New FreedomProfessional users need more than just refined features and performance. They also need the reliability and durability demanded of any professional tool. The Alpha 7S III features a redesigned grip for greater comfort and a secure hold, an improved dust removal feature, plus dust and moisture resistance that maximizes reliability in challenging environments. It includes a durable, reliable HDMI Type-A connector, and is the first Alpha series camera to support USB PD (Power Delivery), allowing higher power to be supplied from an external source so that users can continue to record for extended periods with minimal internal battery usage.Advanced Connectivity for Professional Working EnvironmentsThe Alpha 7S III has been designed and configured to support photo and video journalists and sports shooters who need to deliver stills or movies as quickly as possible with several advanced connectivity options. The camera supports 5GHz24/2.4GHz wireless LAN (IEEE 802.11ac) and offers MIMO (multiple-input and multiple-output) to improve communication quality by using multiple antennas, doubling in speed when compared to the Alpha7R IV. It also carries new USB tethering support25. When connected to a 5G (5th generation technology standard for cellular networks) compatible device such as Sony’s "Xperia 1 II" smartphone via USB cable, it is possible to use 5G network for fast and stable FTP file transfer26. USB to high-speed wired LAN connectivity27 also offers stable and fast FTP transfer for both movies and stills. A USB Type-C™ connector that supports fast S uperSpeed USB 5Gbps (USB 3.2) data transfer is provided, enabling high-speed PC Remote (tethered) data transfer available for smooth handling of large image files.AvailabilityThe new Alpha 7S III Full-frame Interchangeable Lens Camera from Sony will be available from September 2020 at HK$26,990.For customer enquiries, please contact Sony hotline service at (852) 2833-5129.Please click to view: full product details | specificationsA product feature video and a product concept video on the new Alpha 7S III can be viewed.Exclusive stories and exciting new content shot with the new camera and Sony’s other imaging products can be found at , a site created to educate and inspire all fans and customers of Sony’s α - Alpha brand.New content will also be posted directly at the Sony Photo Gallery.About Hong Kong Marketing CompanyHong Kong Marketing Company (HKMC), a division of Sony Corporation of Hong Kong Limited, provides sales, marketing and after sales services for Sony’s consumer electronics products as well as broadcast and professional products in Hong Kong and Macau.

低像素引发的小轰动 索尼α7S深度评测
低像素引发的小轰动索尼α7S深度评测作者：暂无来源：《摄影之友·影像视觉》 2014年第11期作为索尼α7系列机身中最昂贵的一款，α7S的分辨率却是最低的。
我们将带你揭开其中的原因。
翻译：王雷编辑：李硕美编：周蕾索尼现在拥有3款全画幅无反相机，用户可以根据自己最看重的功能特性自由选择。
需要极致分辨率的用户可以选择3600万像素的α7R，而注重暗光环境或视频拍摄的摄影师可以选择1200万像素的α7S。
中间地带则由2400万像素的α7坐阵，能够捕捉足够多的细节，同时又比α7R具有更快的反应速度。
功能特点与α7和α7R相同，α7S采用索尼E卡口，但它的全画幅Exmor CMOS只有1220万有效像素，原生感光度范围ISO100-102400。
最高感光度在拍摄静止与动态影像时还可进一步扩展至409600，目前也只有尼康D4S可以与之抗衡。
索尼还为α7S配备了强大的视频拍摄技术，包括通过HDMI接口外接扩展设备记录4k视频。
做工与操作索尼的α7系列微单（无反）相机创造了新的尺寸标杆。
除了更加突出的手柄，α7S的外形尺寸与奥林巴斯OM-D E-M5非常接近，而后者的感光元件则要小许多。
α7S握在手中给人很坚固的感觉，这要归功于镁铝合金的机身材质。
所有转盘边缘都切削成凸轮形式，很显档次，机身表面的各个控制按钮也给人很精致的感觉。
长时间握持感觉也比较舒适。
与α7和α7R相同，OLED电子取景器可提供出色的观看感受，细节丰富、色彩也很细腻。
随着对拍摄参数的调整，可以直接从取景器画面中看到曝光效果的变化，所以在拍摄之前就能对最终拍摄效果做到心中有数。
3英寸92.1万点可翻转液晶屏的观看效果也很出色，不过在阳光明媚的日子里，设置为烈日观看模式还是非常必要的，即使当太阳躲在云层后面时。
而在拍摄视频时，一个带遮光罩的监视器则是更专业也更好的选择。
性能表现尽管较低的像素数意味着α7S记录的细节没有7或7R那样丰富，甚至比不上1600万像素的尼康D4S，但它拍摄的影像非常清晰锐利，完全可以满足A3尺寸的高质量照片打印。
如何辨别真假SONY芯片
如何辨别真假SONY芯片SONY产品型号及芯片组合－辨别真假SONY芯片：最近几年SONY的芯片其实一直都有间间断断的断货事件。
导致真品的价格一直都是比较高，生产企业没大的量根本无法实现产品价格的大幅度降低。
成本不能降，为何产品价格已是一年比一年低？当然问题有很多，使用质量不好的产品配件，使用更好的生产工艺，使用集团采购降低采购成本，偷漏税，可这些能降低10~20%的价格吧。
但事实是市场上的摄像机价格的降低是其它行业产品所无法比较的。
目前有不少用夏普或其它芯片替代SONY芯片的。
多数为磨去CCD上的产品标记，另做假标签等，造成以假乱真，欺骗消费者的恶劣行径。
做过市场的基本上都知道，480线的SONY CCD摄像机，且不论是否有特别功能，仅一般的480线的SONY CCD摄像机在对工程公司的市场售价仅为三百多元人民币时，做真品的也就只有望而兴叹了。
为了让更多的中国安防监控行业从业人员对产品有所了解，这里贴出SONY产品型号及芯片组合并注明，希望能给市场一个公正的衡量标准。
对消费者能有所教育，1、芯片：CXD3141、CXD1267、CXA2096+ICX405；2、芯片：CXD2163BR、CXD2006、CXD2480R+ICX405；3、芯片：CXD2163BR、CXD2006、CXD2480R+ICX405（调低照度，属假低照）；4、芯片：CXD2163BR、CXD2006、CXD2480R+ICX409；5、芯片：CXD2163BR、CXD2006、CXD2480R+ICX255；6、芯片：CXD2163BR、CXD2006、CXD2480R+ICX259；当前存在的市场问题：1、用2163+ICX405冒充假高线；对策：教客户真高线=2163+ICX409。
2、用2163+ICX405冒充假低照；对策：教客户真低照=2163+ICX255。
3、用ICX409或ICX255冒高线低照；对策：教客户真高线低照=2163+ICX259。

索尼nex7摄影技巧教学1.长时间摄影，请打开LCD，过保的可以考虑撕掉贴纸，会大大提高散热效率。
2.竖着机身，使用从上至下全景扫描可以使得全景照片不至于太广阔3.同上，但是使用大光圈对焦人物，再扫描全景可以产生Brenizer照片效果(模拟广角下大面积背景虚化)4.除尘在每次关机时自动启用,不过Sony的机身除尘是无意义的，超声波除尘也是幌子，皮老虎是必备的，保持电量3格以上，选择菜单->设置->清洗模式->关闭相机，卡口朝下，用镜头刷清洗接口处灰尘，旋开镜头，用皮老虎吹走CMOS上的灰尘，SONY这个除尘系统的特点是低通经过特殊镀膜，不容易粘上灰尘(反过来说一旦黏上了，基本只能靠皮老虎吹下去)5.在室内低光环境，使用HDR模式可以搭配慢速快门拍摄清晰照片，类似于手持夜景效果，但是可以自定义低ISO，根据你使用的镜头支持防震与否，可以减低1-3档次快门。
6.Sel16f28镜头在f8时画质最佳，减少和增加光圈画质都会变差。
7.Sel50f18全开比较锐利，f4-f5.6非常锐利，高于f8逐渐下降。
该镜抗手震模式非常有效，低于1/5依然可以出片。
8.Sel18-200镜头基本素质不错，光圈和18-55类似，广角画质较佳，200mm端色偏严重，特有的Activemode可以减少摄影状态下的手震。
补充说明：18200这颗头也许是我对其长度重量对画质提高期望过大(在使用55-210前，我主要使用该镜头拍摄长焦)，实际拍摄效果我并不是很满意，尤其是长焦部分，边角比55-210肉，对焦时间很慢，同时该镜头由于太重，使得整个机器重心在左手，右手会导致误触到按键。
至于广角部分，上面也说到了，光圈全开时明显比狗头好，边角比狗头锐利很多，形变和色偏微乎其微，但是为此付出的重量大增有点得不偿失。
摄影时这颗头表现非常不错，前面的画质问题在高压缩的视频面前都没什么影响，变焦很顺滑安静，总的来说这是颗很适合摄像用的镜头，并非追求长焦画质的唯一选择。

索尼A7S科普性评测看S-Log
索尼A7S科普性评测看S-Log1曲线早已在专业产品中发挥作用前言：一台“不太正经”的相机，所以才有了这篇文章A7S的评测我们已经上线，详情请点击【全新CMOS极致高感索尼微单A7S详细评测】。
没错，高感无疑是它的绝对优势，但除去高感，1220万有效像素的全画幅CMOS相对于近2W的售价毫无亮点。
如果在网上搜索A7S，会发现大家谈论的焦点都是视频功能。
没错，索尼A7S给人的感觉更像是加错了天赋的微单，视频功能远强于拍照功能，所以一篇额外的视频功能解析会让您更好的了解这款产品。
曲线是A7S视频功能中最主要的优势，也是本篇评测的重点。
可以说曲线是一个隐藏在相机中，很少有人使用但可以改变视频色调、甚至提升画面质量的功能。
在专业视频领域，曲线早已发挥出不可替代的作用：让低成本的设备具备影视级的拍摄效果。
曲线对于普通摄影爱好者来说很陌生，但随着索尼在A7S中下放了专业摄像机的S-Log（曲线,细分名称S-Log2，以下简称S-Log）后我们老百姓也有机会接触到如此高大上的功能。
何为科普性评测？我不仅要测试A7S的视频效果到底好不好，还要告诉您到底什么是S-Log。
索尼ILCE-7S(单机) 产品综述|图片(501)|参数|报价|点评(24) ZOL商城价12480元专注数码服务到家去购买ZOL商城￥12480索尼A7S·S-Log是个相对新鲜的功能A7S三大主打优势：高感、超采样、S-Log，在测试高感以及超采样之前，笔者决定先对更陌生的S-Log进行测试，而且测试前我们必须先看一下使用S-Log拍出的效果。
左图为开启S-Log，右边为正常拍摄（A7S视频截图）开启S-Log后很明显画面变灰了，但有意思的是亮部细节和暗部细节都要优于没有使用S-Log所拍摄的。
也就是说开启S-Log以后可以大大提升画面宽容度，至于灰色的画面后期调整就OK了。
索尼F55拍摄的RAW格式视频截图“视频越灰越好”，这是一个90%正确的命题，另外10%涉及到很多算法问题笔者也无法解答。

这个周末打算把它带回家体验一下超高高光度带来的弱光拍摄体验。
当然，回家路上暂时也没有比较好的拍摄对象，所以先让家里两只小猫一起出出镜。
索尼A7S+蔡司 FE 55mm F1.8由于镜头光圈足够大且机身又擅长高感，所以我索性把机器设置在全手动M档上：快门速度放在1/160s捕捉小猫的动态、光圈F1.8全开看看焦点中心锐度如何。
恩恩，画面的曝光控制就让自动感光度来确定吧——我在这方面一向是能偷懒则偷懒的。
整机用起来手感和A7没有什么两样，镜头对焦也比较干脆。
看了一下直出的JPEG画质，全开光圈锐度与解析都很好。
虽然有很多朋友喜欢给A7系配转接环上其他品牌镜头，但我个人还是比较坚定相信新镜头画质一定比老镜头更好，而且能用原生镜头就不用转接。
对于A7系，我个人觉得能够接受的底线就是上次去用过的沈阳中一光学50mm F0.95镜头了，最近他们好像又出了这支镜头的新版，倒是可以考虑拿来与A7S搭配一下挑战一下极限弱光下的手持拍摄哟~品牌:索尼器材:ILCE-7S 时间:2014-08-14 快门:1/160 光圈:F/1.8 焦距:55毫米感光度:2000品牌:索尼器材:ILCE-7S 时间:2014-08-14 快门:1/160 光圈:F/1.8 焦距:55毫米感光度:640品牌:索尼器材:ILCE-7S 时间:2014-08-14 快门:1/160 光圈:F/1.8 焦距:55毫米感光度:3200品牌:索尼器材:ILCE-7S 时间:2014-08-14 快门:1/160 光圈:F/1.8 焦距:55毫米感光度:3200品牌:索尼器材:ILCE-7S 时间:2014-08-14 快门:1/160 光圈:F/1.8 焦距:55毫米感光度:1600品牌:索尼器材:ILCE-7S 时间:2014-08-14 快门:1/160 光圈:F/1.8 焦距:55毫米感光度:1600今晚开车去到豫园和董家渡附近稍微走了一下，目的是为了能够在比较弱的环境光线下手持拍摄一点索尼A7S+中一光学F0.95标头组合的样张。

Sony α7SⅡ

来源：《咔啪》2015年第12期
源自α7S的iE统进化，机身5轴防抖功能独具魅力
α7系列推出了高感性能超强、动态范围最大的新机型α7SⅡ，与前代α7S相比，新机型像素数保持不变，但新搭载了5轴防抖功能及速度、精度更高的16g点高速智能自动对焦系统，并支持全画幅范围内无插值计算的全像素高分辨率4K视频拍摄功能，实现真正意义上的全面进化。
值得关注的是，α7系列中的“Ⅱ”代机型开始全面搭载5轴防抖功能，可获得相当于4.5挡快门速度的防抖效果，尤其是专为高感光度摄影优化的α7SⅡ，可在几乎任何场景中轻松完成手持拍摄。
新机型与前代α7S的感光度范围相同，均为常用感光度ISO102400（扩展感光度ISO409600）。
简单换算一下，这意味着以相同感光度拍摄时，α7SⅡ可获得高出4.5挡的快门速度，优势明显。
此外，新相机的自动对焦区域大幅度提升至169A（前代机型为25点）。
强劲的高感光度性能意味着画面上噪点更少，而噪点直接影响反差自动对焦的对焦精度。
因此，随着自动对焦区域的进一步细分，新相机在弱光环境中应能更精准地完成对焦，必将在夜间抓拍摄影中发挥巨大威力。
还有，α7SⅡ的目镜使用有机EL面板与采用蔡司T*镀膜的XGA OLED True Finder，取景倍率为0.78倍，同样也是不容忽视的一大亮点。
