What is it?

The Sigma BF is explicitly not trying to be a do-everything, Swiss Army Knife of a camera. Sony’s a7C II already exists, bringing an EVF, multiple dials, a mechanical second-curtain shutter mechanism and in-body image stabilization, for a list price just 10% higher than the BF’s.

But if Sigma was trying to go head-to-head with Sony in the mass market, it probably wouldn’t be spending seven hours milling each camera out of blocks of aluminium, nor doing so in Japan: neither of which is the approach you take if you’re primarily driven to hit a specific price point.

Similarly, just looking at the specs, the BF might be mistaken for an unstabilized Panasonic S9 in a fancier body, but despite sharing a sensor, the two cameras couldn’t be more different.

Instead Sigma explicitly says the BF is designed for ‘everyday’ photography. An elegant object designed to be carried with you, rather than a utilitarian device you take when you’re taking photos. It’s absolutely not optimized for rapid operation, it’s not teeming with clever features. Instead it includes only the bare essentials for photography (or, arguably, slightly less than that, given its lack of mechanical shutter).

Think of it like a Moleskine notebook: in many respects it’s not as practical for taking notes and recording ideas as the smartphone you’re already carrying, but the very process of carrying it with you acts as a prompt to look at the world and capture the thoughts you were having. The BF is trying to do the same.

It’s the difference between a camera that you’d grab when you want to go and take photos of something, vs a tool that encourages you to look for things to photograph.

Body and controls

User interface

The best way to understand the BF is to note the dedicated settings display towards the top right-hand corner on the back of the camera. This displays one of ten parameters:

These are also the ten parameters that appear on the main screen if you press the center button on the back of the camera, in the pattern shown in the table above.

You can navigate between them by pressing the cardinal points on the rear dial, then scroll the dial to change the current setting.

Pressing the center button lets you see and edit the camera’s core ten parameters, but the chosen setting is also shown in the dedicated settings display to the top right of the screen. In this instance the aperture value is shown in dark grey because it’s being controlled from the lens.

But you don’t have to press the center button and bring them up on the main screen: once you’ve learned their relative positions (and chances are it’s the ones in the bottom row you’ll change regularly), you can navigate around them just using the settings display. And, for me, that’s the key to understanding the BF: it’s designed so that the core settings can be adjusted without looking at the main screen. You can set the camera to show all the settings on the main screen,

In keeping with this idea, the touchscreen is almost solely used for positioning the AF point or selecting a subject to track: even if you summon-up the settings on the main screen, you can’t tap to change settings, just choose what to focus on.

Exposure modes

The BF has no mode dial, so exposure mode is set by selecting which parameters you want to be controlled by the camera. This is done via the main screen. Press the center button to bring up the settings then press it again to edit them, and the ISO, aperture value and shutter speed indicators show ‘Auto’ options above them, letting you engage and disengage automated control of each parameter.

Any of the exposure parameters that can’t be changed by spinning the dial, either because they’re set to Auto or because aperture value is being set by an aperture ring, is rendered in darker grey, both in the settings display and on the main screen display.

Other settings

Ten further settings, including the level gauge and options to display information such as focal length and focus distance are accessed via the three-dot button. Navigating down to the word ‘System’ takes you to the menu where fundamental settings such as date and time are edited.

Another ten settings, six of which relate to how much detail appears on the main screen (exposure parameters, guides, virtual horizon, etc), can be accessed by pressing the ‘three dots’ settings button. At the bottom of this settings menu is the word ‘System’ which gives you access to a ten-option-long list of fundamental camera settings, including firmware information, copyright information, menu language and date/time.

That’s the extent of the BF’s interface: ten top-level parameters, ten settings and ten menu options. But what this doesn’t fully convey is the degree to which it’s a camera in which Shutter speed, Aperture value, Exposure compensation and ISO can all be set using just the settings display, leaving the monitor solely for focus and composition.

Handling

The BF is a very solid-feeling camera, as you might expect from something hewn from a solid block of metal. The body itself is relatively light but the weight adds up as soon as you mount a lens of any appreciable size on it.

Despite it’s minimalist appearance, it’s quite easy to hold. The textured front-plate and raised thumb rest at the back mean you can get a pretty solid grip on the camera, and you can cradle the weight of the lens in your left hand if you’re working with anything larger than one of the compact primes offered by Sigma or Panasonic.

However, we found that it was common for our ring finger to wrap around to the base of the camera as we held it, which quickly makes apparent how sharply angled the edge of the BF is. It’s not hard to imagine users adding a little tape to the lower edge of the camera or being tempted to chamfer the edge with a fine file, once they come to live with the camera.

I’ve primarily used it with the Sigma 35mm F2 prime and the Panasonic 20-60mm F3.5-5.6 lenses, both of which are small and light enough that it’s been comfortable to use.

Battery

The BF uses a new 11.88Wh BP-81 battery. This will power the camera to a CIPA rating of 260 shots per charge. As always, the CIPA figure will tend to under-represent how many shots you’re likely to get, and we found it’s the camera’s propensity to show its charge percentage on its settings display that caused us to worry a little disproportionately.

Still, a rating of 260 is pretty low and means you may want to consider carrying a power bank if you plan to do more than occasional shots each day. Putting it on to charge overnight, just as you might do with your phone will probably be sufficient for everyday casual use, though.

A gentle press of the power button puts the camera into standby mode, but the battery will continue to drain at an appreciable rate. The BF starts up from cold quickly enough that this is usually a better approach.

Initial impressions

Even the body cap is an over-engineered delight.

The Sigma BF is one of the most unusual cameras we’ve ever encountered. On paper it looks like an under-specced rival to the Panasonic DC-S9 or even the Sony a7C II. Or, perhaps even a slightly re-purposed Sigma fp. But, even though it shares components and a small rectangular body, the BF is quite unlike any of these cameras.

Sigma’s CEO, Kazuto Yamaki talked about completely re-thinking the camera’s interface to pare it back to the fundamental things a camera needs to offer, in an attempt to make it simple to use, with the aim of making a camera for everyday use. And the more I use the BF, the more I think I understand this intent.

The idea of a dedicated settings display, leaving the main screen as a means of composing your image and positioning the focus point is a refreshingly simple one, undermined only by the challenge of viewing a fixed LCD in bright light. The decision to display only one setting, rather than a full array of settings and icons makes it very quick to interpret and I did find it made me consider what changes I wanted to make, shot-to-shot, in a way I don’t on a more conventional twin-dial camera.

Playback mode has three levels of information that can be displayed, this is the most detailed, but you can also opt just to see the top two rows of information, or just the first. Touching, rather than pressing, the playback button lets you review the last image you shot, without entering the full playback mode, for as long as your finger remains on the button.

This really hit home when I realized I prefer to set aperture from the camera, rather than using an aperture ring; I think the camera works best with everything controlled from the settings display, rather than trying to increase the number of control points.

Another surprise was how good the BF’s autofocus appears to be. Its subject tracking is very simple to use and impressively tenacious, while its eye detection works well and can be left turned on without minimal risk of the camera prioritizing nearby faces ahead of a different subject you’ve selected.

There are distinct downsides, though. The lack of mechanical shutter not only means there’s a risk of rolling shutter and that the camera can’t be used with flash, it also means it’s quite prone to banding caused by the inherent flicker of artificial lights. This can be fairly subtle at longer shutter speeds but becomes increasingly apparent in short exposures, limiting its use as an indoor camera, despite a sensor that works well in low light.

Sigma’s sometimes quite dramatic color modes may not be to everyone’s tastes, and I’m not wholly convinced by the ‘Light Source Priority’ auto white balance mode, that tries to maintain some of the character of the detected light source. But even when the results are unexpected, they’re often interesting.

The BF’s battery life is also quite short. An external charger is available, if you want to keep a second battery topped-up, but mainly it’s a case of remembering to put the camera on to charge regularly, just as you might for your smartphone.

Other than a slight concern about the sharp lower front edge, I’m really looking forward to spending more time with the BF. It’s not a camera that lets you respond quickly to the unexpected; instead it’s one that makes you slow down and look for the photos you might otherwise not notice.

Canon Announced its PowerShot V1 compact just a few weeks ago, with pre-orders only recently opening for those in Asia. Despite that, DCWatch reported that Canon has already warned that demand is high and delivery may be delayed as a result, potentially delaying its availability to the rest of the world.

A screenshot of the messaging on Canon Japan’s website.

Visiting the PowerShot V1 product page reveals a message (translated from Japanese) stating, “Apologies and information regarding product supply status.” That message links to a page that briefly explains that Canon is “currently receiving more orders than expected for the following products, which is causing delays in delivery.” Notably, three compact cameras are affected, with the PowerShot V1 at the top of the list. Canon plans to ship these products sequentially but says delivery may take longer than usual.

The PowerShot V1 is the company’s first compact camera since the PowerShot G7 X III, which was released back in July 2019. Canon also launched the PowerShot V10 in June 2023, but that model is more video-focused and targets a different user base. Even though the Powershot V1 is only available in Asia, it is a welcome addition. After all, we are currently seeing an increased interest in compact cameras, which is driving up prices and causing issues with availability across the board.

The increased demand is reflected across the compact market. Retro compacts that used to sell for $5 at garage sales and thrift stores now go for anywhere from $40 to $250 or even higher. The PowerShot G7 X III, despite being six years old, has such high demand that Canon is suspending orders indefinitely to catch up. Meanwhile, the Fujifilm X100VI, which was announced a year ago, is still out of stock on most websites and is selling for as much as double its already steep $1,599 retail price on sites like eBay. CIPA’s January numbers also showed a rise in the popularity of compact cameras, with an increase in shipments and value compared to January 2024.

While The PowerShot V1 was released exclusively for Asia, many are eagerly waiting for broader availability. Unfortunately, a delay so early on in the release potentially complicates that, meaning those hoping to get their hands on the camera outside of Asia will likely have to wait even longer. Canon hasn’t provided specific timing or details on the extent of the delays. That means it’s a waiting game for now, with another compact camera bogged down by supply constraints.

The Camera and Imaging Product Association (CIPA) recently published its total production and shipment data for January. The latest data shows that demand for compact cameras remains strong. Shipments of interchangeable lens systems also increased year over year, while those of SLR systems slowed.

CIPA breaks down its data into camera types, with dedicated sections for cameras with built-in lenses and interchangeable lens systems. It also differentiates between SLRs and mirrorless cameras and provides specific data regarding various regions. All digital still cameras saw a 6% increase in shipment compared to January 2024 data, while interchangeable lens cameras were up 5% year-over-year.

Built-in lens systems, though, saw the biggest increase of all categories. With 124,085 units shipped in January, cameras with integrated lenses saw an increase in shipments of 11% compared to January last year. Also notable was the 50% increase in the value of shipped compact cameras compared to January last year. The fact that the value is increasing faster than the number of units shipped indicates prices are higher for those cameras.

The growth in value isn’t entirely surprising, given that demand for compacts is high right now. Cameras like the Fujifilm X100VI have been extremely popular. According to Map Camera, one of the largest photography retailers in Japan, the Fujifilm X100VI was its best-selling camera in February 2025. The buzz surrounding the Canon Powershot V1, which was only recently announced at CP+, is also significant. The Powershot V1 is only available in Asia and wasn’t scheduled to start shipping until April. Despite all that, DCWatch reported that Canon has already announced it is experiencing supply shortage issues and that delivery times may be longer than usual as a result.

While that growth in compact camera shipments is interesting, it seems to be largely the result of two regions. China saw the greatest increase; shipments of compact cameras grew substantially year-over-year, with just 6,055 units shipped in January 2024 versus 18,955 units shipped in January 2025, a 213% increase. Asia (excluding China and Japan) also saw an increase, though at a more modest 22%. Europe and the Americas, however, actually saw a few thousand fewer shipments of compact cameras year-over-year (around a 6% fall).

While compacts saw an increase in shipments, SLRs saw a decline in January 2025 compared to January 2024. Shipments of SLRs were down 16% year-over-year. This isn’t much of a surprise, given that the last DLSR that was released was the Pentax K-3 Mark III in March 2021, and Canon and Nikon last released DSLRs in 2018 and 2020, respectively. Sigma is also no longer developing new DSLR lenses. Needless to say, it seems the sun is setting on DSLRs, so it makes sense that shipments would be slowing.
