正是！

这是个好消息！

嗯，明白！连续对焦对全程对焦速度要求不是那么高，关键是看焦点附近一定范围内的扑捉焦点的对焦速度如何，按那个测试视频以及花老的看法，转接C口超长焦时的连续对焦速度一般应该能满足A7RII的5FPS要求，只是看能应对多快目标运动速度了，这也正是我想知道的。

A7RII是划时代的产品，

因为从A7RII开始你可以把能高速自动对焦AF镜头的选择扩大到佳能的镜头群和尼康的镜头群，

可以从MTF曲线选择镜头而不需要考虑它是那家生产的镜头，

因为转接后都可以使用索尼的微单（无反数码）最先进混合对焦系统的智能、多维、飘逸、准确的对焦+追焦锁定目标拍摄之凝固精彩瞬间。

是滴，

行货保修无问题。

感谢照片交流和同样感受的切磋。

过几天雾霾消退后咱就出门拍摄，

几千张以后就心知肚明。

升级完后使用感觉又是新的惊喜，

更多镜头可以使用，

过去老固件可以使用的镜头现在更快，

快的令人忘记单反和微单的差异。

花老，您这身板儿

不抖？

感谢你这个市※※的专职摄影师的关注！

那到不是，

是5DS/5DSR的高像素吸引，

可是5DS/5DSR的高感使我犹豫，

A7RII买了以后就淡化了对5DS/5DSR的思念，

为A7RII配置佳能640时候备用方案就是A7RII不灵光时候给640配置佳能机身，

佳能机身考虑就是7DII（目前超越1DX对焦的最强对焦系统）和1DX，

因为高感所以更倾向1DX，

也许1DX II上市的时候就是进1DX的时机或许永远不重返单反（15套数码单反的购买经历后，咱已经决定基本不在单反再投入，特例除外），

这全看A7RII的表现是否可以应付小型鸟的飞版拍摄（练习手动对焦拍摄小型鸟的飞版已经快一年啦，期待A7RII转接后使用AF的飞版拍摄效果）。

当然A7系列转接索尼、美能达、柯尼卡美能达AF镜头使用索尼2、4带转接环在AF自动对焦中扑捉小型鸟的飞版是无任何问题（如下图），但是咱希望使用佳能、尼康的镜头在AF自动对焦中拍摄（从此补齐索尼镜头群）。 本帖最后由 花冠摄影 于 2015-10-7 09:16 编辑

Sony Semiconductor Solutions Corporation to be Established
Reinforcing Devices Segment
Tweet

Sony Corporation has been implementing a series of measures to reinforce its Devices segment, a key growth driver for the Sony Group. As part of these measures, Sony will adopt a new operational structure for its Devices segment. The aim of this new structure is to enable each of the three main businesses within this segment, namely the semiconductor, battery and storage media businesses, to more rapidly adapt to their respective changing market environments and generate sustained growth. The Devices segment will continue to be overseen by Tomoyuki Suzuki, Executive Deputy President and Corporate Executive Officer, Sony Corporation.

In the semiconductor business, where image sensors are a primary area of focus, Sony will establish Sony Semiconductor Solutions Corporation ("Sony Semiconductor Solutions") to further reinforce this business, and concentrate on sustained growth. R&D, business control, sales and other operations related to the semiconductor business, which are currently overseen by business groups and R&D units within Sony Corporation, will be transferred to Sony Semiconductor Solutions. The new company will aim to commence operations on April 1, 2016. As part of its mid-term corporate strategy announced in February 2015, Sony outlined its intention to sequentially split out the business units currently within Sony Corporation and operate them alongside existing Sony Group companies. The aim of these measures is to ensure clearly attributable accountability and responsibility from the perspective of shareholders, management policies with an emphasis on sustainable profit generation, and the acceleration of decision-making processes and reinforcement of business competitiveness. The decision to establish Sony Semiconductor Solutions forms part of this strategy.

Terushi Shimizu, currently Deputy President, Device Solutions Business Group, Sony Corporation, is expected to be appointed President, Sony Semiconductor Solutions. Sony Semiconductor Corporation (President: Yasuhiro Ueda) and Sony LSI Design Inc. (President: Makoto Ishii), which cover Sony's semiconductor manufacturing and design operations respectively, will become subsidiaries of Sony Semiconductor Solutions.

In the battery business, Sony Energy Devices Corporation (President: Yoshito Ezure) will continue to engage in integrated business and manufacturing operations. It will remain focused on reinforcing business operations and enhancing product competitiveness, in order to maximize opportunities for expansion in the growing battery market, and enhance its ability to generate profit.

In the storage media business, business functions currently located within Sony Corporation will be transferred to Sony Storage Media and Devices Corporation (President: Mitsunobu Saito), which currently engages in manufacturing. By integrating these business functions and manufacturing operations, the Company aims to ensure continued, stable profit generation. Sony also targets April 2016 for the completion of this transfer.

其实这个视频已经展现的很明显啦，

全程搜目标时候走焦很慢，

到了焦点附近就很快，

特别是焦点附近一定范围内的扑捉焦点的对焦那是飞快，

建议你重新看视频琢磨那些焦点快和那些焦点慢，

自然你就明白我首页说的那些归纳的话。

我能购买全新640防抖第二代专门配置给A7RII就说明A7RII一定可以使用，

我自己当初的考虑是A7RII不行还可以配置5DS/5DSR、1DX或者7DII（7DII的对焦系统比1DX先进，应该是未来1DX II的对焦系统，但是高感太差），

5DS/5DSR已经淘汰了对5DSR的思恋（5DS除去细节略弱以外，全面比5DSR测试分值高一点点），

你看看我曾经说过自己在考虑重返单反就是这个原委，

.........

我目前还没有打算配置1DX或者7DII（还停留在机会中）。

俺不清楚转接C家超长焦头连续对焦性能如何？能否达到本家E和A头水平？能否进行5fps动态题材的拍摄？这是俺最关心的问题，毕竟C家超长焦可选余地大的多。

俺对佳能口的适马新120-300f2.8很感兴趣，关学素质很不错，变焦使用又方便，现在价格也下来了，遗憾没A口，好在E口是个万能后背，所以对转接C家超长焦能否实现高速连续对焦很关心。
