楼主，我也有EOS5，怎么不知道眼控对焦？你说的EOS3吧。

如果你是当年购买的EOS 5QD新机身则拿出使用说明书看眼控对焦的操作介绍。

如果是买的二手的EOS 5QD机身则搜索如何操作使用，

搜索不到得时候告知我，

我拍摄使用说明书的介绍页给你。

A1和R5的高感还是差了一点，不然就真的是完美机型了。

A1如你所言，高感指标再提高一个台阶就完美。

但是相对A1来看或者强求R5完美度的话，那么R5还有几个短板是：明显果冻效果，有黑屏拍摄，AI识别主体和背景弱一些，连拍每秒刚刚20张，8K略弱。

我就想知道果冻效应和a9ii比怎么样

看过佳能、索尼各自官网的介绍和官方拍摄效果介绍，

应该差不多是一样的效果（一样的堆栈技术本身带的大幅进步），

为什么？

因为是背照堆栈超超高速读出数据的速度决定了绝大部分的拍摄仅仅有轻微的果冻效果。

后面佳能会不会挤牙膏，堆栈成为r3和r1的专利。。

只要领先很多和王者地位稳固后，

谁不挤牙膏？！

想看看暗部的噪点。

我有EOS R3的RAW文件，

室内照明灯下我特意强制提升快门到64000分之一秒后，

迫使ISO飚高到25600，

但是我目前没有软件可以打开RAW文件，

这是偶然性（一般称作工程样机）得到，

就给你看看文件缩略图的截图（是RAW文件 + JPG文件）和一张JPG拍摄数据像素截图。

Finally - my real world review of the new Canon R3 camera!
The first time I got my hands on the Canon R3 (pre-production) camera was in the weeks before I headed out to Tokyo to photograph the Olympic Games. I was allowed to show a photo of me holding the camera, but I was not allowed to show any more images of the camera or say much more than what I posted. Yes, it was a tease, but I was bound by the NDA I signed with Canon.

Now the camera has been officially announced and I can talk freely. Normally I would have pre-written this blog and posted on the day of Canon's announcement, but I was flying back from spending a month in Africa and did not have a chance to do so. So...let me tell you about my experience with the Canon R3.

First impression

On that day back in early July, I was waiting anxiously for the FedEx box to arrive and could not wait to rip it open to see the R3 in person. The first thing I noticed was that the camera was noticeably smaller and lighter than the Canon 1DX MKIII. I even put it next to the 1DX to confirm my first thoughts. I was also happy to see that it used the same batteries as the Canon 1D series.

Having used the Canon R5 and Canon R6 for some time, all the buttons and dials were in familiar places, so using the camera seemed easy. The one noticeable difference was the over-sized eye piece, which was made larger to support the new eye control. More on that later...

I played with the camera and took a bunch of test photos. I had a lot of questions about the setup, and had numerous calls with the technical people at Canon to fully understand the new features and to fine-tune the camera for what I wanted. My goal was to set up the camera for optimal shooting at the Olympics, with dual back-button focus and having the eye-control trained for my pupil. As it turned out, I ended up using a newer version of the Canon R3 in Tokyo and had to retrain that camera, but I made notes of everything I had changed at home, so it was easy to make those adjustments at the Olympics.

Real-world use at the Olympics

I went to Tokyo with two Canon R5 cameras, a bunch of lenses, lots of ProGrade Digital memory cards, and knew that I would be getting an R3 when I arrived at the Games. My original plan was to shoot with the Canon R5 cameras as my primary cameras, and use the Canon R3 as my "test camera" for those times when I was not contractually obligated to shoot for Team USA.  But that changed almost immediately! I started using the Canon R3 at the Opening Ceremony and never stopped. The Canon R5 cameras basically sat in my camera bags for most of the Olympics.

The Canon R3 is blazing fast, with the ability to capture up to 30 frames per second. This may not be needed by all photographers, but at the Olympics it was amazing.

This fast frame rate allowed me to capture the peak of action much easier than in Olympics past.

I love that the Canon R3 is silent when shooting since it is a mirrorless camera, but I also really appreciated that Canon added a simulated shutter sound, that can be turned on and off. As a long-time DSLR shooter, I have grown accustomed to hearing my shutter speed. It was a welcome feature during these games.

I did not always use the fastest setting, as it was not needed for all photos. For this multi-exposure shot, I wanted a slightly slower burst rate, so that the images did not stack up on each other too closely.

But...when I needed to capture that key moment, the Canon R3 came through beautifully.

Johnny Hooper is known for his strength in the pool, and I captured this image of him rising high out of the water during the men's last game. Having a super fast frame rate allowed me to grab that one image at the top of his shot, with his body highest out of the water. That same fast frame rate also meant that I had a lot more images to go through after each game. I still remember the first time I shot a water polo game, downloaded the photos in the press room, and saw that I had bursted out 2600 images during the one hour game. Yikes! Being under such a tight deadline, this added a new wrinkle into my workflow, but the better images made up for the slight delay in culling speed.

The most asked question "What is the resolution?"

The most asked question for the last two months was "Can you tell us how many megapixels the camera is?" And of course I could not. But as many of you saw, there were numerous photography sites that grabbed my photos, dissected them and determined that the camera is 24MP. Is that enough? For most of my photography, this is plenty of resolution.  USA Water Polo currently has large billboards in Southern California using one of my images from the Tokyo Olympics, and it was taken at 24MP. Heck, I remember using 4MP cameras in the past and having those images enlarged to 4' by 8' at trade shows. Do I wish for more megapixels in the Canon R3? Yeah, maybe a little more would be nice. But I really did not need more for what I was shooting and I was not cropping much. I can tell you that in Africa I was using two Canon R5 cameras and loved the ability to shoot small birds, crop in on the images, and still have good sized files to print.

Focus speed and eye-control

In the last couple of days, I have had many people ask me about the focus speed and eye-control of the Canon R3 and their overall effectiveness. I can tell you that the focus speed of the R3 was top-notch, giving me a very high percentage of "keepers" from each event. When shooting the fast action of the Olympics, it is a tall order to ask for all images to be tack sharp. This new camera did an amazing job of locking focus.

I used eye-detection for some of the sports, but also chose to go "old school" and use a single point back-button focus for many of the events. There were many times when I would not be facing the athletes head on, or I had so many people in the frame that the camera did not know who to focus on. This is where the eye-control would be most welcome, and I had high hopes to use this at the Games. But I was using a pre-production camera and the eye-control did not seem fast enough at the time for this action. I should have tried it more, but since I was under pressure to get my photos every day, I chose to turn it off most of the time. With that said, I think that the eye-control will be awesome for my event photography, allowing me to lock focus on my chosen subjects for portraits, weddings, bar mitzvah or corporate events.

My challenges with the Canon R3

Honestly, there are not many things to pick on with this new camera. But you know me, and you know that I am really demanding with my camera gear. The one thing that I did not like about the Canon R3 is that Canon chose to have one CFexpress card slot and one SD card slot. I always write RAW images to both cards when I am shooting (for redundancy), and since the SD card is so much slower than the CFexpress card, I have numerous times when I filled the camera buffer and missed some great shots. For the USA Water Polo women's gold medal game, I decided to pull the SD card and shoot to just the CFexpress card. I could not risk having buffer issues during this key game!

I should mention that I shot the entire Olympics in RAW+JPEG mode, since I could not easily open a Canon R3 RAW file and had to work with the JPEGs for the whole Games. I wanted to capture the RAW files, since I plan on re-editing the best photos from the RAW files in the weeks to come, once Adobe has added the R3 to Adobe Camera RAW. Shooting RAW+JPEG really slows things down, and I don't plan on shooting that way in the future.

Overall impression of the camera

Not everyone needs a camera that performs at the level of the Canon R3, but for those of us who need to fire off 30 frames per second, need the super fast focus speeds, and want the very best, this camera is awesome. Ever since using the Canon R5 and Canon R6 for my photography, I knew that mirrorless was the way to go. The new Canon R3 brings all the power of the Canon 1D series to the mirrorless world, and that is a welcome addition to the Canon line-up. Canon may not like me saying this, but for anyone looking to purchase a Canon 1DX MKIII, I would recommend going with the Canon R3. I think that the R series is the future for Canon, with all the new lenses coming out for these new bodies, and the camera just performs better in so many respects.

最后——我对新佳能R3相机的真实世界回顾！

我第一次接触到佳能R3(前期制作)相机在我前往东京拍摄奥运会前的几周。我被允许展示一张我拿着相机的照片，但我不被允许展示更多的相机图像或说比我发布的更多的话。是的，这是一种戏弄，但我被我与佳能签署的NDA所束缚。

现在相机已经正式公布，我可以畅所欲言了。通常情况下，我会预先写好这篇博客，并在佳能发布的当天发布，但我在非洲呆了一个月，然后飞回来，没有机会这样做。因此...让我告诉你使用佳能R3我的经验。

1、第一印象

早在7月初的那一天，我焦急地等待联邦快递箱的到来，迫不及待地撕开它，亲自去看R3。我注意到的第一件事是相机明显比佳能1DX MKIII。我甚至把它放在1DX旁边，以确认我的第一想法。我也很高兴看到它使用了与佳能1D系列相同的电池。

使用了佳能R5和佳能R6有一段时间，所有的按钮和转盘都在熟悉的地方，所以使用相机似乎很容易。一个明显的区别是尺寸过大的眼罩，它被做得更大以支持新的眼睛控制。稍后详细介绍...

我玩着相机，拍了一堆测试照片。我有很多关于设置的问题，并与佳能的技术人员进行了多次通话，以充分了解新功能，并根据我的需求微调相机。我的目标是在奥运会上为最佳拍摄设置摄像机，采用双后按钮对焦，并为我的学生训练眼睛控制。事实证明，我最终使用了更新版本的佳能R3在东京，我不得不重新训练相机，但我把我在家里改变的一切都做了笔记，所以在奥运会上做这些调整很容易。

2、奥运会上的真实使用

我和两个人去了东京佳能R5相机，一堆镜头，很多进步数字存储卡，并且知道当我到达奥运会时，我会得到一个R3。我最初的计划是用佳能R5相机作为我的主要相机拍摄，并在我没有合同义务为美国队拍摄的时候使用佳能R3作为我的“测试相机”。但这几乎立即改变了！我开始使用佳能R3在开幕式上，从未停止。这佳能R5在奥运会的大部分时间里，相机基本上都放在我的相机包里。

这佳能R3速度极快，每秒可捕捉30帧。这可能不是所有摄影师都需要的，但在奥运会上，这是令人惊叹的。

这种快速的帧速率让我比过去的奥运会更容易捕捉到动作的高峰。

我喜欢佳能R3拍摄时是无声的既然是无反光镜相机，但我也真的很欣赏佳能加了模拟快门声，那就可以开、关了。作为一个长期的DSLR射手，我已经习惯了听到我的快门速度。在这些比赛中，这是一个受欢迎的特点。

我并不总是使用最快的设置，因为不是所有的照片都需要它。对于这种多曝光拍摄，我想要稍微慢一点的爆发速率，这样图像就不会彼此堆叠得太紧密。

但是...当我需要抓住那个关键时刻时佳能R3很漂亮地通过了。

约翰尼·胡珀以他在游泳池中的力量而闻名，我捕捉到了他在男子最后一场比赛中高高跃起的画面。拥有超快的帧速率让我可以在他的镜头顶部捕捉到那张照片，他的身体最高露出水面。同样的快帧速率也意味着我在每场比赛后有更多的图像要看。我还记得第一次拍水球比赛，在新闻发布室下载照片，看到在一个小时的比赛中爆出来2600张图片。哎呀！在如此紧迫的截止日期下，这给我的工作流程增加了一条新的皱纹，但更好的图像弥补了剔除速度的轻微延迟。

3、最常被问到的问题“分辨率是什么？”

过去两个月问得最多的问题是“你能告诉我们相机有多少百万像素吗？”当然我不能。但是正如你们很多人看到的，有很多摄影网站抓取了我的照片，对它们进行了解剖，并确定相机是24MP。够了吗？对于我的大多数摄影作品来说，这是足够的分辨率。美国水球目前在南加州有大型广告牌，使用的是我在东京奥运会上拍摄的一张照片，拍摄速度为24MP。见鬼，我记得过去使用4MP相机，在交易会上把那些图像放大到4英寸乘8英寸。我希望佳能R3有更多的百万像素吗？是啊，也许再多一点就好了。但是我真的不需要更多的东西来拍摄，而且我也没有收获太多。我可以告诉你，在非洲我用了两个佳能R5相机和喜爱的能力，拍摄小鸟，作物在图像上，仍然有良好的大小文件打印。

4、聚焦速度和眼睛控制

在过去的几天里，我有很多人问我的对焦速度和眼睛控制佳能R3以及它们的整体有效性。我可以告诉你，R3的聚焦速度是一流的，让我在每个项目中都有很高的“守卫者”比例。在拍摄奥运会的快速动作时，要求所有的图像都清晰是一个很高的要求。这台新相机在锁定焦点方面做得非常出色。

我在一些运动中使用了眼睛检测，但也选择了“老派”，在许多项目中使用单点后退按钮焦点。很多时候，我不会正面面对运动员，或者我的镜头里有很多人，以至于摄像机不知道该聚焦谁。这是眼睛控制最受欢迎的地方，我对在奥运会上使用它寄予厚望。但是我用的是一台前期制作的相机，当时的眼球控制似乎不够快。本来应该多试试的，但是因为每天都有拍照的压力，所以大部分时间都选择关机。话虽如此，我认为眼睛控制对我的活动摄影来说将是非常棒的，让我能够专注于我选择的肖像、婚礼、成人礼或公司活动的主题。

5、我对佳能R3的挑战

老实说，这台新相机没什么可挑剔的。但是你了解我，你知道我对我的摄影器材要求很高。我不喜欢的一点是佳能R3就是佳能选择了一个CFexpress卡槽和一个SD卡槽。我在拍摄时总是将RAW图像写入两张卡(为了冗余)，由于SD卡比CFexpress卡慢得多，我有无数次填满相机缓冲区，错过了一些很棒的镜头。美国水球女子金牌赛，我决定拉SD卡，拍到了刚好CFexpress卡。我不能冒险在这个关键游戏中有缓冲问题！

我应该提到的是，我在RAW+JPEG模式下拍摄了整个奥运会，因为我不能轻松打开佳能R3 RAW文件，必须在整个奥运会中使用JPEG。我想捕捉原始文件，因为我计划在接下来的几周内重新编辑原始文件中最好的照片，一旦Adobe将R3添加到Adobe相机原始文件中。拍摄RAW+JPEG真的会减慢拍摄速度，我也不打算以后用那种方式拍摄。

6、相机的整体印象

不是每个人都需要一台性能与佳能R3，但是对于我们这些需要每秒30帧，需要超快的对焦速度，并且想要最好的相机的人来说，这款相机太棒了。自从使用佳能R5和佳能R6对于我的摄影，我知道无反光镜才是正道。新的佳能R3将佳能1D系列的所有力量带到了无镜世界，这是佳能阵容中受欢迎的一员。佳能可能不喜欢我这么说，但对于任何想购买佳能1DX MKIII的人来说，我建议您选择佳能R3。我认为R系列是佳能的未来，所有新的镜头都将为这些新的机身问世，相机只是在许多方面表现得更好。

A1如你所言，高感指标再提高一个台阶就完美。

但是相对A1来看或者强求R5完美度的话，那么R5还有几个 ...

定位EOS 1DX Mark III这类高价的高像机 买这机用户 比R5多花2万元 应该知道是想要的是什么。
