友善交流我如果有这类问题的思考（仅供交流，悟做参考）：

风光拍摄者更需要细节表现力。

旅游摄影者更喜欢轻量化的器材。

索尼的机身都有多帧降噪、手持夜景多帧合成、防抖多帧合成的技术，在这些模式下拍摄风景片无需考虑噪点问题，因为都非常非常低（如果选择项中有索尼机身，那么风光摄影中使用索尼特殊降噪技术后，任何噪点顾虑可以忽略）。

在胶片时代单反、单电、微单、DC都是用一样规格的胶卷，它们的画质区别主要来自镜头。

在数码时代单反、单电、微单、DC初期不都是用一样规格的CMOS和CCD，它们的画质区别来自画幅大小和镜头差异，但是目前的索尼是唯一全系规格都使用全画幅CMOS的厂家，那么它们的区别回归到胶片时代。

镜头带来的区别如果可以转接到任意机身，那么镜头影响画质的因素可以忽略（微单转接可以全实现，佳能单反转接可以少部分实现），你可以微单+转接环，根据需要的镜头选择携带而无需考虑机身问题（使用微单从此一改考量的习惯）。

从胶片时代到数码时代，各个级别、规格的机身操控的方便性和专业性从来就不一样，是悖论嘀。

风光摄影因细节的需要+便携的考虑，当下选择5000万数码和轻便是必需嘀。

因为微单的出现，选择的宽容性和组合的任意性就囊括了你可以的无限组合。

所以各自答案各自明................。

我和摄友交流看到了5000万像素机型后，期盼1亿像素的愿景（读采访佳能的报导文章）在71、71、73楼。





你可以从这篇报导预知一些端倪。

Inside story: the man behind the EOS 5DS and EOS 5DS R
CPN recently got the unique opportunity to meet and talk to Tsunemasa Ohara - Senior General Manager of Camera Research and Development at Canon Inc. - who is the key man behind the development of the revolutionary 50.6 Megapixel Canon EOS 5DS and EOS 5DS R DSLRs. In an exclusive interview he reveals how he came up with the concept for the cameras and how and why some of the key technologies contained within them were developed...

CANON PROFESSIONAL NETWORK (CPN): Who came up with the idea and vision for EOS 5DS and EOS 5DS R?

TSUNEMASA OHARA (TO): “It was my idea to develop this product as I knew from my past research that more megapixels could be achieved from the EOS 5D Mark III sensor. Once I advised that such a product would be achievable I brought together a team to work with me, many of whom were the same people who had worked with me before on other EOS DSLR projects.”

Tsunemasa Ohara (pictured above with an EOS 5DS) of Canon Inc. had the vision for a high-megapixel DSLR and led the EOS 5DS and EOS 5DS R development team.
CPN: What are the key technical advantages of the cameras compared to existing competitor high-resolution DSLRs and medium format cameras?

TO: “In terms of megapixels, the EOS 5DS and EOS 5DS R are almost the same as a medium format camera and offer the same levels of image quality too. The key advantage from an EOS perspective is that handling and mobility is much better than a medium format camera. This is a major advantage with our product because it is smaller and lighter and can be used in a wider variety of situations.”

CPN: What criteria did you place on developing this new sensor?

TO: “The first criteria – as with all EOS cameras – was high image quality. To achieve this was our first priority. From a development point of view it was possible to increase the megapixel size even more but, from an image quality perspective, to do that alone was not good. Therefore achieving the optimum balance between high megapixels and high image quality was our most important objective at all times.”

CPN: Will this significant sensor advance and technology be limited purely to EOS 5DS and EOS 5DS R, or will it find its way into more EOS cameras during the next few years?

TO: “To achieve this high-megapixel CMOS sensor we developed many new technologies for this sensor to be used in the EOS 5DS and EOS 5DS R bodies. We can’t reveal what we will do next, but certainly some of the technology will find its way into future cameras.”

CPN: The Dual DIGIC 6 processors make these very quick cameras in terms of image processing. But how far can you go with DIGIC architecture in terms of speed?

TO: “We have not reached the end of the development of the DIGIC processor yet. We are aiming for higher levels of processing speeds all the time and continue to do so.”

CPN: Please explain how you arrived at this version of a low-pass filter on the EOS 5DS and why did you choose to deploy a cancellation filter on EOS 5DS R?

TO: “Our main camera is the EOS 5DS which, like all EOS DSLRs, has a low-pass filter fitted to avoid moiré. As you know, [the] EOS 5DS is a high-megapixel model and to use this sensor we had to find a way to use it most effectively to prevent moiré. Of course if we remove the filter, then moiré appears in pictures of certain subjects and this is not good for image quality. But, on the other hand, in some cases where the subject has no patterns or straight edges then moiré does not appear. For these cases, we developed the EOS 5DS R with a low-pass cancellation filter which allows for the ultimate in resolution for organic subjects.”

CPN: The crop ratios are an interesting feature. Why did you feel the need to offer these in-camera?

TO: “We realise that certain photographers shoot in a certain style, or with a certain crop, and knew that our new CMOS sensor would allow for these crop ratios to be utilised in-camera. We feel that by adding these, it increases [the] EOS 5DS and EOS 5DS R functionality and usability.”

CPN: There is some superb micro-engineering here, especially the Mirror Vibration Control System. Please explain why and how this was developed?

TO: “We developed this system originally for the EOS 7D Mark II and have re-designed it slightly for the larger sensor and mirror combination of EOS 5DS. The difference in sensor size between the APS-C and the full-frame sensor means we have to control the mirror differently because it is bigger. Using cams to operate the mirror means we can control, much more precisely, its operation with the objective to cause no vibration in the camera.”

CPN: We are curious as to why the EOS 5DS and EOS 5DS R cameras lack headphone sockets when they can record HD movies… Why is this?

TO: “We ran out of room! By equipping the EOS 5DS and EOS 5DS R with USB 3.0 – which was important to transfer such high levels of image data – unfortunately we didn’t have any space left for headphones in the existing EOS 5D Mark III body shell used for these cameras.”

CPN: What do you see as the potential future for Canon high-resolution cameras? Where might the technology be in five years time?

TO: “There is a demand for high-megapixel [cameras] and high-resolution and, of course, we will continue on this quest in the future and to try to satisfy this demand. As you know, in August 2010, we announced a 120-million pixel APS-H CMOS sensor... so we have shown that we have the technology to produce even higher resolution sensors, but we must also focus on high image quality, too. So DIGIC processing, and all the other algorithms that contribute to high image quality, we need to work on too. It is the overall package that makes Canon EOS digital cameras so successful.” 本帖最后由 womailehuaguan 于 2015-2-12 09:14 编辑

如果交流时候使用缩小图像尺寸看图（缩小到20000 x 1497尺寸），

那么缩图后各种噪点会大幅减少得到自动降噪（无形中提升了高感）。

如果认可使用安全快门以上的快门就是廉价的自然防抖，

那么A7R超高像素的机型就具备缩图的更好高感和高于安全快门的链接防抖功能！

可以自己淘宝买外壳自己更换（拆卸顺序做记录、拍照为安装无误做的必要准备）最便宜，

可以淘宝买外壳带到摄影器材城的维修厂家付费更换比较便宜、简便、快捷，

直接送佳能自己的保修店最贵、时间可能长但是质量有保证。

一下是淘宝佳能6D外壳的链接和截图。

《入魔报导低可信消息，索尼E口新全画幅旗舰机身可能的惊人参数。》

(SR1) A likely fake rumor we all wish would have become true…

An anonymous source sent me that rumor and it sounds more like a wishful thinking. For now we only are sure Sony will announce new FE lenses at CP+ and that’s it. I wish there would be more and I wish that the anonymous source would be right

So just to let you dream a bit …here is what I got and what you don’t have to take seriously for now:

“Sony has a new global electronic shutter sensor that will be put into our new flagship e-mount camera. The top shutter speed is 1/32000 with flash sync capabilities at that speed（E口的旗舰机将使用全域电子快门、1/32000秒的快门速度和闪光同步）.
Sensor resolution will be well above 50MP（5000万以上的像素）
It will have In body stabilization like the A7II（A7II防抖设计）
A new type of AF will be implemented, it is like DFD from Panasonic but faster（全新的堪比松下DFD对焦能力）.
196 points of autofocus covering 94%（196对焦点覆盖94%的区域）
-2 ev af acquisition（-2EV的AF）
faster autofocus than current a6000 CIPA rated（比A6000更强的对焦）
no 4k on this camera（没有4K）
NEW Bionz X2 processor, 70% faster per core (quad core)（比4核快70%的新处理器）
no pricing on camera just yet, expected to be $2700-$3000 for body（机身可能定价在2700到3000美元）
TWO new lenses will be unveiled: 85mm Zeiss 1.8 with the performance of the 55mm Zeiss. 135-400mm Sony G 5.6 lens. pricing will be $1300 and $2000（两只新全画幅镜头，蔡司85mmF1.8就如以前出的蔡司55mmF1.8一样优秀，135-400mmF5.6G镜头，价格分别是1300美元和2000美元）
Also: a new A mount camera will be announced, the same processor and DFD like AF module will be in the new camera, as well as SLT flip up mirror mechanism.（一个新的A口机身）
NEW flagship Flash F63M name designation（新的顶级闪光灯F63M）
NEW A mount adapter for E mount for APS sensor with a77II AF module（一个使用A77II对焦系统的E口转接环）
NEW hotshoe XLR and 3.5mm MI shoe audio input device（新XLR和3.5mm MI）
NEW wireless trigger remote for wifi enabled cameras“（新WIFI）

I really would love to believe in such a rumor…but sadly it’s 95% likely it’s not going to happen. We will have to wait a couple of weeks more to see Sony’s new cameras (likely March before the NAB show).（真希望上述消息是真的，你只看看就可以，别太认真，等待到3月可能就明朗啦）

P.S.: I once did the mistake to not post the A7s rumor I got from an anonymous source. Didn’t believe a 12MP FF sensor with a half million ISO would come. And it happened. So let’s hope they will come again such an incredible rumor I rate with SR1 or SR2 will become true（让我们再一次期待这些低可信的消息就如同当初A7S那样出人意料的兑现了全部的谣传）

一句话点醒他，

“优质镜头是马，顶级机身依然是鞍；好马不常换，好鞍也随时可以更新；别做买了只驴子却配个金鞍的傻事。”

如果这句话他不醒，

随他去走多数摄友必经的进阶烧钱之路，那样他获得了浪费的弯路和快乐的过程。

在《5000万像素的时代到来，咱像素数可以接受的底线痛苦并快乐的被进阶地抬高着ing...》贴48楼中发感慨。

咱2004年开始使用数码相机后留下的深刻记忆有，

佳能单反数码相机的1系开启了数字全画幅规格的数码时代。

奥林巴斯和松下创新使用4/3单反的感光元件撬动了全新数码相机之规格领域（短法兰距的微单市场）。

索尼打开的全画幅CMOS的普遍应用（单反、单电、微单、DC、摄像机都全面使用36 X 24 的全画幅CMOS）。

索尼A7S首次使用的全画幅相机的电子快门（真正的快门无声的静音技术）预示未来的超高速快门和超高速连拍的各种可能性。

超高像素时代的到来：
1、尼康D800、D800E开启的超高像素之门
2、哈苏H5D的位移合成2亿像素（通过传感器防抖装置移动像素/传感器实现“超高分辨率”的技术）
3、佳能5DS、5DSR的CMOS制造工业光刻的5000万像素
4、奥林巴斯E-M5 Mark II的位移合成6000万像素（通过传感器防抖装置移动像素/传感器实现“超高分辨率”的技术）

奥林巴斯启动的传感器五轴防抖技术以及随后索尼进而延伸出来的传感器防抖装置移动像素合成更高分辨率的技术。

咱当下展望之期盼：更新的CMOS技术带来惊天地的宽容度，更新摄影领域的更多观念。

看看5000万像素的宾得645Z就可以知道一波更新换代的器材潮应该来临，

因为竞争惠及我们的腰包和器材愿景的时期来临了（2015年到2018年）。
