Sigma BF 评测（2026）：古怪却又出奇地讨人喜欢
WIRED WIRED 评测
TIRED 不足之处
Sigma has a long history of releasing, let’s call them, eccentric cameras. Last year, the brand put out the BF, which continues in that tradition. Because it is very different, lacking features like a mechanical shutter, viewfinder, and storage-card slot, among others, I wanted to spend some extra time with it before passing judgment. After using it for months, I’ve decided that the Sigma BF is the perfect camera for people who love using cameras more than they enjoy taking photographs.
适马（Sigma）一直以来都有发布所谓“古怪”相机的传统。去年，该品牌推出了 BF，延续了这一风格。由于它非常与众不同，缺乏机械快门、取景器和存储卡槽等功能，我在下结论前想多花些时间体验它。经过几个月的试用，我认定 Sigma BF 是那种比起拍照本身，更热爱“使用相机”这一过程的人的完美选择。
I don’t mean that as a slight necessarily—I think it’s fine to love the tool without paying mind to the fruits of its labor. I have an entire collection of antique hand planes I very rarely use, but they look really nice on display. I get it. This design approach does have consequences though, and one big one is that the Sigma BF can be frustrating when you’re trying to actually take pictures.
我这并不是在贬低它——我认为热爱工具本身而不去在意产出成果是完全没问题的。我收藏了一整套古董刨子，虽然很少使用，但它们摆在那里看起来真的很棒。我理解这种心态。不过，这种设计理念确实会带来后果，其中一个主要问题是，当你真的想用 Sigma BF 拍照时，它可能会让你感到沮丧。
Beautiful Foolishness 美丽的愚行
The Sigma BF takes its name from the phrase “beautiful foolishness,” which Sigma pulled from a poem in The Book of Tea. I mention this because its name neatly sets the stage for what the Sigma BF aims to accomplish. The camera is not trying to compete with high-end, full-frame cameras from Sony, Canon, Nikon, or any other legacy maker. In fact, Sigma seems to have known that it couldn’t face off against those heavy hitters, so it built its own playing field. The success or failure of the BF ultimately depends entirely on you and whether you fit on Sigma’s beautiful field of (potentially) foolishness.
Sigma BF 的名字取自“美丽的愚行”（beautiful foolishness）这一短语，这是适马从《茶之书》的一首诗中汲取的灵感。我提到这一点是因为这个名字恰如其分地为 Sigma BF 的定位定下了基调。这款相机并不打算与索尼、佳能、尼康或其他传统大厂的高端全画幅相机竞争。事实上，适马似乎很清楚自己无法与这些行业巨头正面交锋，因此它开辟了自己的赛道。BF 的成败最终完全取决于你，以及你是否愿意踏入适马这片“美丽的（潜在的）愚行”领域。
Let’s start with the basics—the dirt on the field, as it were. The design choices here are all about the aesthetics of the camera, not how it works. I could argue about whether that’s good or bad, but either way, it’s important to know before you consider buying one.
让我们从基础开始——也就是这片赛道上的“泥土”。这里的设计选择完全是为了相机的外观美学，而非功能性。我可以争论这到底是好是坏，但无论如何，在你考虑购买之前，了解这一点非常重要。
In my 15 years of reviewing cameras, I’ve always refused to use the phrase “feels good in the hand,” but, well, I’m going to come very close right now because I think it’s important to say that the Sigma BF feels very bad in the hand. Bad enough that no one in the design process could have missed it. The body is a single piece of machined aluminum—a beautiful metal box with no concessions whatsoever to pedestrian concerns like ergonomics. It’s awkward to hold, no matter how you try to do it. A one-handed grip feels downright健身 dangerous; using two hands works, but the BF still feels clunky and sharp. Because, well, it is.
在我 15 年的相机评测生涯中，我一直拒绝使用“手感舒适”这个词，但现在，我不得不说，Sigma BF 的手感非常糟糕。糟糕到设计过程中的任何人都无法忽视这一点。机身是一整块加工铝材——一个漂亮的金属盒子，完全没有向人体工程学这种平庸的考量做出任何妥协。无论你怎么拿，它都显得很别扭。单手握持感觉非常危险；双手握持虽然可行，但 BF 依然显得笨重且边缘锋利。因为，它确实就是这样。
The simple truth is, this camera is unpleasant to hold for long periods of time. You could get around this with a third-party grip, but then you lose the aesthetic appeal, and at that point, you’re going against the spirit of the thing.
简单的事实是，这款相机长时间握持并不舒服。你可以通过第三方手柄来解决这个问题，但那样会破坏它的美感，而到了那个地步，你就违背了这款相机的设计初衷。
The BF features a 24 megapixel full-frame sensor in a very blockish, extremely minimalist body. The body is lightweight and available in either black or silver. It takes L-mount lenses. Sigma provided me with a 35 f/2 DG lens, along with a 90 f/2.8 DG. I primarily shot with the 35, which weighs roughly the same as the body and feels pretty well-balanced. I’d be curious to try the Sigma 45 f/2.8 DG ($619), which is marginally smaller and lighter and might feel better on the BF body. Even better than that would be some pancake lenses, but so far, Sigma has not made any for this body.
BF 在一个非常方正、极简的机身内搭载了一枚 2400 万像素的全画幅传感器。机身轻便，有黑色和银色可选，支持 L 卡口镜头。适马为我提供了 35mm f/2 DG 和 90mm f/2.8 DG 两款镜头。我主要使用 35mm 镜头拍摄，它的重量与机身大致相当，平衡感相当不错。我很好奇尝试一下适马 45mm f/2.8 DG（售价 619 美元），它稍微更小更轻，或许在 BF 机身上手感会更好。如果能有饼干镜头就更好了，但到目前为止，适马还没有为这款机身推出过任何饼干镜头。
After months of shooting with it, I don’t mind that it’s chunky and awkward to hold. The only thing in the overly designed body that bothers me is that there’s only a strap anchor, which means you’re limited to using wrist straps exclusively. I find this odd, simply because it seems like at least one market for the BF is the person who likes to have an aesthetically pleasing camera hanging around their neck, which isn’t possible here. There may be some straps out there that would let it hang vertically, with both sides of the strap on the single anchor point, but none of the straps I tried worked this way; the anchor point was too small to get both sides of a strap attached.
经过几个月的拍摄，我并不介意它厚重且握持别扭。在这个过度设计的机身上，唯一让我困扰的是它只有一个背带挂点，这意味着你只能使用腕带。我觉得这很奇怪，因为 BF 的目标市场之一似乎是那些喜欢把美观的相机挂在脖子上的人，而这在这里是无法实现的。市面上或许有一些背带能让它垂直悬挂，将背带的两端固定在同一个挂点上，但我尝试过的所有背带都行不通；挂点太小了，无法同时容纳背带的两端。
Despite it being awkward to hold and attach to yourself, I like the overall design of the camera’s body. I like the button layout, which consists of four buttons and a toggle wheel. I also like that only one button is an actual physical button, and the rest are haptic. The menu and control system are well-designed and functional, and I found the little electronic window that displays pertinent info depending on what you’re doing (battery life, f-stop, shutter speed, etc) to be really nice.
尽管握持和携带都很别扭，但我还是喜欢这款相机机身的整体设计。我喜欢它的按键布局，由四个按键和一个拨轮组成。我也喜欢它只有一个物理按键，其余都是触觉反馈按键。菜单和控制系统设计得很好且功能齐全，我发现那个能根据操作显示相关信息（电池寿命、光圈、快门速度等）的小电子窗口非常棒。
The downside of the camera’s minimalism is that it’s, frankly, cumbersome in fully manual mode. The lack of dials means adjusting shutter speeds, and ISO requires going into the menus using the touchscreen. After a few days of doing this, I realized that the Sigma BF may be full-frame, but for practical use, it’s very much a point-and-shoot camera. I got all my best shots in what I’d call aperture priority mode, with ISO and shutter set to auto, as I controlled the aperture via the lens.
这款相机极简主义的缺点在于，坦率地说，在全手动模式下操作非常繁琐。缺乏拨轮意味着调整快门速度和 ISO 需要通过触摸屏进入菜单。几天操作下来，我意识到 Sigma BF 虽然是全画幅，但在实际使用中，它更像是一台“傻瓜相机”。我所有最好的照片都是在所谓的“光圈优先”模式下拍摄的，将 ISO 和快门设为自动，通过镜头控制光圈。
The image quality is excellent. The 24-megapixel sensor is very sharp, and while it might be nice to have something more like 36 megapixels for better cropping capability, I never felt limited by the sensor. I primarily shot RAW images and came to really enjoy Sigma’s color rendering, which yields a distinctive, cool-skewing tone. Sigma does have some film simulations you can use to emulate different looks when shooting JPG, but I didn’t use them much beyond testing. I also found these more interesting when shooting video than stills.
画质非常出色。2400 万像素的传感器非常锐利，虽然如果能有 3600 万像素以便更好地裁剪会更好，但我从未感到受限于传感器。我主要拍摄 RAW 格式照片，并逐渐非常喜欢适马的色彩渲染，它能产生一种独特的、偏冷的色调。适马确实提供了一些胶片模拟功能，可以在拍摄 JPG 时模拟不同的外观，但我除了测试之外并没有怎么使用。我也发现这些功能在拍摄视频时比拍摄静态照片更有趣。
