Sony A1 review

索尼A1评测

On paper, the Sony A1 can do absolutely everything. But how well does it measure up to Sony's big claims? We are putting this beast of a camera to the test to find out.

理论上，索尼A1可以做任何事情。但它与索尼宣传是否相符呢？让我们来测试这台相机找出答案。

The A1 is the most technologically advanced, innovative Sony camera to date. It's one of the best mirrorless cameras ever built, and it should be for a whopping $6500. Therefore, the primary market for this camera is professional sports, action and wildlife photographers, where being able to shoot at 30FPS is a huge advantage. It's also an excellent option for videographers who can shoot incredible 8K videos. But investing in such an expensive camera is a huge decision, so we'll be running through some of its best features and the pros & cons to help you decide whether it is worth the sizable investment.

A1是索尼迄今为止技术最先进、最具创新性的相机。这是一台有史以来最好的无反光镜相机，价格惊人，6500美元。因此，这款相机的主要市场是专业的体育、动作和野外摄影师，能够以30 fps的速度拍摄是其巨大优势。对于能够拍摄令人难以置信的8K视频摄像师来说，A1也是一个很好的选择。但购买如此昂贵的相机是一个重大决定，所以我们将通过其最佳功能和利弊运行分析，帮助您决定它是否值得高额投资。

Handy dials for focus and shooting modes

方便的对焦和拍摄模式旋钮

Much better menu system

更好的菜单系统

Sensor cover

传感器盖

The A1 has all the design features you'd expect from a Sony camera — mode dial, exposure compensation, customizable buttons, etc., so we won't go too much into that. Still, a few newer features make this camera exciting.

A1拥有索尼相机的所有设计特色-模式转盘、曝光补偿、可定制按钮等，对此我们就不多说了。尽管如此，一些新功能使这款相机令人兴奋。

One of the most significant new design features is the dials on the top of the body. Canon has added two handy dials on the left — one for focus and another for shooting modes. Having these controls on the body rather than in the menu system frees up the custom buttons for other controls, which we think is a great feature. However, one minor niggle with the control dials is that to change the setting, you need to push and hold the button while you move the dial. The only button that doesn't have this is the exposure compensation, which is a push to lock, making it much easier to use.

其中一个最重要的新设计特点是机身顶部的旋钮。佳能在左边增加了两个便捷盘-一个用于对焦，另一个用于拍摄模式。将这些控件放在主体上而不是菜单系统中，可以为其他控件释放自定义按钮，我们认为这是其一个很好的特性。然而，控制盘的一个小问题是，要改变设置，你需要在移动盘的同时按住按钮。唯一没有这个功能的按钮是曝光补偿，采用按钮锁定，使它更容易使用。

This camera also has an updated menu system which is much more intuitive than previous models. The layout is a thousand times better and easier to navigate.

这款相机还拥有更新的菜单系统，比之前的型号更直观。布局更是好一千倍，更易于导航。

It features the same LCD screen that Sony has always used however, we would have liked it to have been fully articulating rather than just tilting. The electronic viewfinder has over nine million dots and 9x magnification.

它的特点是采用索尼一直使用的同一液晶显示屏，然而，我们希望它已经完全清晰，而不是只倾斜。电子取景器有超过900万个点和9倍放大率。

A sensor cover also completely covers the sensor when the camera is not in use. This is a great feature to prevent dust, sand, dirt, etc., from getting onto your sensor when changing your lenses out in the field. Why is this not in every camera!?

当相机不使用时，传感器盖也可以完全覆盖传感器。在现场更换镜头时，这个特点可以很好的防止灰尘、沙子、污垢等接触到传感器。为什么不是每台摄像机都有！

Fast buffer clearing

快速清除缓冲区

Impressive dynamic range

出色的动态范围

Incredibly accurate eye af and tracking

令人难以置信的精确眼自动对焦和跟踪

The A1 is Sony's best camera in the color department, and the dynamic range is better than the A9 and the A2. The buffer-clearing speed is impressive, although this largely depends on what type of memory card you're using. The buffer also clears while you shoot, so you don't have to wait to start shooting again, which makes life much easier.

在色彩上A1是索尼最好的相机，动态范围比A9和A2更好。尽管缓冲区清除速度在很大程度上取决于使用的存储卡类型，但其依然令人印象深刻。缓冲区拍摄时也会清除，所以不必等待再次重启拍摄，让生活变得更轻松。

The A1 also offers lossless compressed RAW files, which no other Sony camera does. Lossless compressed is essentially the same image quality as uncompressed raw files, but the camera finds intelligent ways to get rid of some of the information which isn't of any use. The file size of a lossless compressed file comes out at about half the size of an uncompressed raw file with basically no quality loss, making it much more efficient and less of a strain on your storage system.

A1还提供无损压缩RAW文件，这是其他索尼相机所没有的。无损压缩的图像质量与未压缩的原始文件基本相同，但相机会会用智能方法来去除一些无用信息。在没有质量损失的前提下，无损压缩文件的文件大小约为未压缩原始文件的一半，使其效率更高，存储系统压力更小。

However, to shoot at the 30FPS the camera states it can do, you need to be using compressed raw as lossless compressed can only hit 20FPS (t is though that is still very good!). It's also worth noting that 30FPS isn't always achievable with every lens, including some native Sony lenses. Many lenses can only achieve around 15-20FPS, which is more than enough for many photographers.

然而，要拍摄在30 fps的相机状态，就需要使用压缩原始文件，因为无损压缩只能达到20 fps（虽然这样，但依然很棒！）同样值得注意的是，并不是每个镜头，包括一些索尼原生镜头，都能实现30 FPS。很多镜头只能达到15- 20 FPS左右，这对于很多摄影师来说已经绰绰有余。

As expected, this camera's eye autofocus and live tracking are nearly flawless. It's an incredibly responsive camera with no issues tracking its subject. It even has a bird mode in addition to the human and animal eye AF modes.

正如预期的那样，这款相机的眼睛自动对焦和实时跟踪几乎完美无瑕。跟踪物体时，响应相机没有任何问题，令人难以置信。除了人眼和动物眼睛自动对焦模式外，它甚至还有鸟模式。

8K video shooting

8K视频拍摄

Mechanical and electronic shutter

机械电子快门

Can switch to APS-C crop

可切换至APS-C剪辑

A huge selling point of this camera is its 8K video capabilities. This camera should be at the top of your wishlist if you're a photographer who also heavily shoots video. It does have its limitations, though.

这款相机的一个大卖点是它的8K视频功能。如果你是一个摄影师需要大量拍摄视频，这款相机应该是你的首选。当然它也有局限性。

One of the more significant issues this camera faces when shooting 8K video is overheating. It performs well in a temperature-controlled climate, but the video shooting time dramatically reduces under direct sunlight, even when the overheating level warning is set to high. It averages around 90 minutes of shooting time before it shuts down due to overheating. This is fine for many of what users would need it for, but it would not be ideal if you are shooting long podcasts or concerts. It does have a fast recovery time though — it only needs about five minutes before you can start shooting again and you should be good for another hour. Another thing worth noting is that 8K eats up the battery life about 30 percent faster than 4K.

这款相机在拍摄8 K视频时面临的一个比较显著的问题是过热。它在温度受控的气候条件下表现良好，但在阳光直射下，即使过热警告级别设置到高档位，视频拍摄时间也会大幅缩短。在过热关闭之前，平均拍摄时间约90分钟。这对许多用户来说已经很不错了，但对于拍摄长播客或音乐会，就不是很理想了。但是它有一个快速恢复时间-只需要大约五分钟，就可以再次开始拍摄，可以再接着用一个小时。另一件值得注意的是，8 K消耗电池寿命的速度比4K快30%。

The Sony A1 also supports the s-cinetone recording profile borrowed from its cinema camera lineup. The s-cinetone profile delivers a beautiful dynamic range and looks good right out of the camera.

索尼A1还支持s-cinetone录制配置文件，这一功能是从其影院摄像机阵容中借用的。s-cinetone配置文件提供了一个美丽的动态范围，在相机里拍出来就看起来很好。

Another newer feature of this camera is the ability to choose whether you want to use a mechanical or electronic shutter. Switching to an electronic shutter means you can access the higher frame rates this camera is capable of with barely any difference in image quality. It also means you can eliminate shutter shake, which is beneficial if you're shooting at slower speeds without a tripod. The A1 can also switch to APS-C crop mode with images of over 20MP.

这款相机的另一个新功能是能够选择使用机械快门还是电子快门。切换到电子快门意味着可以访问更高的帧速率，图像质量几乎没有任何差异。如果拍摄速度较慢并且没有三脚架，还可以消除快门抖动。A1还可以切换到APS-C裁剪模式，图像超过2000万像素。

Unless you make a living as a photographer, the A1 will likely be far too expensive. It's an absolute powerhouse for video and photography, able to shoot massive 50.1MP stills photos using lossless compressed RAW files at 20FPS max burst speeds and up to 30FPS using compressed RAW files. It excels as a hybrid camera though thanks to its 8K 30P video shooting resolution and s-cinetone recording profile. However, its price will make it inaccessible for many photographers, which is a shame for all those that don't own it. That said, if you can afford it, you won't regret it.

除非你以摄影为生，否则A1可能太贵了。A1是视频和摄影的绝对动力源泉，能够以20 FPS的最大连拍速度使用无损压缩RAW文件拍摄5010万像素的大量的静态照片，使用压缩RAW文件拍摄时最高可达30 FPS。这台混合相机的8 K 30 P视频拍摄分辨率和s-cinetone录制配置文件令其表现优异。然而，昂贵的价格将使许多摄影师望而却步，没有拥有的人会稍觉惋惜。也就是说，买得起，就不会后悔。

The Sony A1 is often compared to the Sony A7S III (opens in new tab). Although the A7S III only has a 12MP sensor, it's still receiving rave customer reviews. It's $3000 less than the A1, so it's a great alternative if you're not looking for such a powerhouse.

索尼A1经常被拿来与索尼（在新选项卡中打开）进行比较。虽然A7S III只有一个12MP传感器，但它仍然得到了客户的好评。如果你不准备购买A1这个动力源泉的话，比A1价格低3000美元的A7S III，也是一个不错的选择，。

The only real direct competitor to the Sony A1, we think, is the Canon EOS R5. The performance of the Sony is on par with the R5, but thanks to the bigger sensor, the A1 'wins' in terms of image quality. The Sony has five and a half stops of shake reduction instead of Canon's eight stops, but the Sony A1 can shoot more frames per second. The R5 is an incredible comparable camera for almost half the price, check out our hands-on Canon R5 review to see what we thought of it.

索尼A1唯一真正的直接竞争对手，我们认为，是佳能EOS R5。索尼的性能与R5不相上下，但由于传感器更大，A1在图像质量方面“获胜”。佳能有八个震动减少，而索尼只有五个半，但索尼A1可以每秒拍摄更多的帧。R5价格几乎是A1的一半，查看佳能R5的实践评论看看是不是与我们预想的一样。

Another great alternative would be the Sony A7R IV (opens in new tab). If you aren't too fussed about being able to shoot up to 30FPS and are more interested in higher image quality, the A7R IV would be a great option with its whopping 61MP sensor. The A7R IV is also much more affordable than the A1. You can read our full Sony A7R IV review here.

另一个不错的替代品是索尼A7R IV（在新标签页中打开）。如果你对30FPS不太在意，而是对更高图像质量更感兴趣，拥有巨大61MP传感器的A7R IV将是一个不错的选择。A7R IV的价格也比A1实惠得多。这里有完整的索尼A7R IV评论。
