Gavin Free, one half of the YouTube duo The Slow Mo Guys, is a camera nerd through and through. His 2015 video “Inside a Camera at 10,000fps” was one of the catalysts for me deciding to actually learn about the technical side of photography, rather than treating my camera as a sort of magic box that takes photos. But slow-motion videography and cameras have changed a lot since then, which is why it’s so exciting that he’s taken another run at the subject. 

The video he released today covers way more than the mirror and shutter mechanism of DSLRs, though he goes into that a bit too. It also shows the exact way that electronic first curtain (or, really, mechanical second curtain) shutters work, how they synchronize with a lens’s aperture mechanism and captures a leaf shutter in action. The video also covers various flash sync modes, showing how a camera manages to capture the light from a strobe, and explaining the things that can go wrong in that process (especially when using High-Speed Sync). 

If you’ve never dug into how a camera shutter works, this video is an excellent primer. Sure, you can figure it out by reading metaphors and explainers and looking at diagrams and animations (and those help you go deeper on a subject), but watching extremely slow-motion footage gives you a very visceral understanding of what’s happening. And if you are familiar with a camera’s mechanisms, it’s still fun to see them in action, in both high definition and slow motion. One thing I learned from the video is just how much the blades of a leaf shutter jiggle when it closes; it’s the kind of thing that really makes you appreciate just what a marvel of precision engineering and manufacturing cameras are.

This year started out quite quiet for new cameras and almost as quiet for photography-related gear in general. We saw some lenses and a few cameras trickled out in the first half of the year, each of which told us something interesting about the market, but there have been fewer releases than in past years. Thankfully, this week marked a bit of a shift, and we suddenly had some actually new products to share. In case you missed some of it, here’s all we saw over the last seven days. 

OM System PEN

Richard Butler

Perhaps the standout launch this week was the OM System PEN, a compact, Micro Four Thirds camera built around a 20MP sensor that marks the first time in a decade that a Pen camera has been sold in North America. The camera is aimed at travel and everyday use, offering a compact build with retro styling at a very reasonable price.

OM System M.Zuiko Digital 14-42mm F3.5-5.6 III

OM System

Released alongside the PEN was an updated model of OM System’s standard zoom, the M.Zuiko Digital 14-42mm F3.5-5.6 III (28-84mm equiv.). The new version is a small upgrade, but it finally offers weather sealing and lets you focus more closely. It is slightly larger than its predecessor, but it’s still quite small for what it is, fitting nicely on cameras like the new PEN. 

Laowa 180mm F4.5 1.5x Ultra Macro APO for X and F-mount

Laowa

While not a new lens, Laowa announced this week that the previously released 180mm F4.5 1.5x Ultra Macro APO is now available for Fujifilm X-mount and Nikon F-mount. It is the first autofocus Laowa lens available for X-mount, and offers a 270mm equiv. field of view on Fujifilm’s APS-C cameras. The price is also a pleasant feature: it costs just $499. 

Sony FE 8-14mm F3.5 Fisheye G

Dale Baskin

Sony released a lens this week that is a first in its lens lineup. The FE 8-14mm F3.5 Fisheye G is the company’s first standalone fisheye lens for E-mount, and it says it’s the most compact lens of this type. At 8mm, the lens provides a circular fisheye image, which will be very familiar to anyone who watched 90’s skateboarding or music videos, while zooming to 14mm results in an image that fills the frame. 

Sigma 20-60mm F2.8-4 DG Contemporary

Sigma / Jack Redgate

Sigma announced two lenses this week, one of which was the 20-60mm F2.8-4 DG Contemporary, a kit lens upgrade for E and L-mounts that is remarkably compact. It weighs 385g (13.6oz), and is 88mm (3.5″) long at its shortest (it extends as you zoom). It is limited in on-lens controls, but Sigma says it’s dust and splash-resistant, and at $849, it’s relatively affordable, too. 

Sigma 85mm F1.2 DG Art

Sigma

For those looking for a more portrait-focused lens, the new Sigma 85mm F1.2 DG Art may be of interest. Like the above lens, it is available for E and L-mounts and is the company’s third F1.2 prime lens, joining 35mm and 50mm options. A lens of this type will have some bulk, but Sigma says it is the “smallest and lightest in its class,” and it weighs just 905g (31.9oz). It’s also significantly more affordable than the Canon and Nikon 85mm F1.2 lenses, coming in at $1599. You can see sample images from the lens here. 

Nine Nikon cinema lenses

Nikon

Not to be left out of the slew of announcements this week, Nikon announced it will be releasing a series of nine T1.9 cinema lenses. Details are still sparse on most of them, including availability, pricing and focal lengths, but it did say one of the nine lenses will be a 50mm. We’ll have to wait for more details, but it does appear Nikon is busy at least.

Fujifilm XF 400mm F4.5 R LM OIS WR

Abby Ferguson

Fujifilm released the XF 400mm F4.5 R LM OIS WR at the end of last week, but for the sake of thoroughness, we’re including it here. The $3200 super-telephoto prime lens rounds out its trio of such lenses, joining the XF 500mm F5.6 R LM OIS WR and XF 200mm F2 R LM OIS WR. It provides a 609mm equivalent focal length on X-mount cameras, and is relatively compact and lightweight for what it is. 

Apple iPhone 18 Pro, iPhone 18 Pro Max and iPhone Duo

Apple

Shifting gears away from lenses, this week marked the release of Apple’s latest iPhone lineup, which includes the iPhone 18 Pro, 18 Pro Max and Duo. The most notable update from a camera perspective is the variable aperture found on the main camera of the 18 Pro and Pro Max, which ranges from F1.48 to F4. It also finally unlocks manual control over some settings within the native camera app.  

The Duo is Apple’s long-awaited entry into the folding phone market, and while it doesn’t feature very advanced cameras, it does offer some camera tricks. 

Insta360 Luna Pro

Mykim Dang

Lastly, Insta360 announced the global release of its Luna Pro, a single-lens gimbal camera aimed at creators who want a portable, stabilized camera for social-ready video. It keeps the specs of the main camera found on the Luna Ultra, and comes in at $600, $170 less than its dual-lens sibling. You can see our hands-on footage here. 

Photographers usually discuss focal length in millimeters. But the San Diego Air & Space Museum’s newly unpacked reconnaissance camera is identified in inches: 24 of them, or roughly 610mm. According to the museum, an even longer 48-inch version followed. 

The camera was part of a cache of unused 1960s-era equipment supplied with the museum’s Lockheed A-12, the CIA’s Mach 3 reconnaissance aircraft and the predecessor to the SR-71 Blackbird. The video is nearly 20 minutes long and begins with substantial background on the A-12 (it is an aviation channel, after all) so photographers may want to jump to the 11:47 mark, where the museum gets into the cameras and how they were used. 

In the video, host Gordon Permann walks through some of the challenges of making a sharp photograph from about 80,000 feet while traveling at roughly 2500 mph. The ground would move hundreds of feet beneath the aircraft during an exposure, resulting in a blurred image. Making matters worse, neither the aircraft nor the terrain would necessarily be level. The solution was motion compensation: the camera itself would “skew,” or make a small movement as its aperture opened, counteracting image smear.

Another fascinating feature is simply how much film these systems used. Permann first shows the standard film canister used in reconnaissance aircraft from the 1950s through the 1990s, which he says held roughly 1200 feet of film. But the A-12 and SR-71 Blackbird needed still more film, so a larger canister was made. The museum has one of those, too, which Permann lifts in the video. He explains that the larger camera used a five-inch-wide film strip, with around 4.5 inches of usable image area. Each individual frame measured about six feet long.

Permann says the system could image more than 100,000 square miles in a single hour, capturing huge swathes of land or sea at once. He also recounts a Blackbird making a turn with its camera running and pointed out to sea. When the film was developed, analysts reportedly spotted a U.S. destroyer on the horizon, 94 miles away, and were able to identify the ship’s type despite the distance.

A separate, still-factory-wrapped camera in another crate is the real mystery: its 1953 date predates the A-12 project by six years, so it couldn’t have come from a Blackbird-family aircraft. The museum is seeking the public’s help to identify what airplane it may have been used on, so anyone with a theory can head to the video and share it in the comments.

Earlier this week, Sigma fully unveiled the 85mm F1.2 Art, a lens it announced would be coming earlier this year. We had the chance to shoot with it, and mainly focused on testing out its capabilities for portraiture, as that’s the traditional use for fast 85mm primes.

You can check out the sample gallery below to judge its performance for yourself. 

We found that shooting with it was the characteristically refined experience that we’ve come to expect from Sigma’s Art-series lenses. While a quality F1.2 lens will never be the smallest or lightest option, we appreciated that this particular lens is light for what it is; Sigma actually claims it’s the smallest and lightest full-frame 85mm F1.2 with autofocus for mirrorless cameras. It feels like something you could conceivably carry around all day without having to worry about waking up the next morning to an unusably sore arm (though I had it paired with an original Panasonic S1R, so it still made for a relatively hefty setup). 

The controls on the lens are also well-judged. I always appreciate a clicked aperture ring, though Sigma also lets you de-click it if you prefer. It’s also nice that you can lock it either into or out of the ‘A’ mode that hands over control of the aperture to the camera body.

While we haven’t put the lens through a full battery of tests to determine every aspect of its image quality, it’s hard to find much fault with the samples we’ve taken. It’s quite sharp across the frame, even at F1.2 (though obviously you’ll be working with razor-thin depth of field), though there’s definitely some chromatic aberration present. There’s also relatively strong vignetting at F1.2, which isn’t necessarily a surprise given the lens’s size, though it largely clears up by F2.8.

Whether you think the trade-offs of an F1.2 lens are worth it over an F1.4 or F1.8 will largely depend on your thirst for light and background blur. But before now, your options for this kind of lens on E and L-mount were limited to non-existent, so it’s nice that we’re getting a genuinely good option, especially one that comes in at just over half of what Nikon and Canon will charge you for a similarly-speced lens.

This week, Apple announced the iPhone 18 Pro, the latest entry in its lineup of high-end smartphones. As we’ve come to expect, the update includes several new camera features, and even some new hardware. So how does it stack up against the last few years of Pro phones from Apple?

Before we get to what’s changed, let’s quickly cover what stayed the same: the 48MP ultra-wide camera, which provides a 13mm equiv. field of view and uses a 1/2.55 (23.5mm²) sensor, is the same model on the iPhones 16, 17 and 18 Pro. Likewise, Apple hasn’t updated the selfie or telephoto cameras on the 18 Pro either; they’re the same ones from the iPhone 17 Pro (though they were upgrades from those of the 16 Pro).

It’s also worth stating up front that the camera layouts on the 18 Pro are the same whether you go with the standard or Max versions, leaving you free to decide whether you want a 6.3″ or 6.9″ display, without having to worry that you’re compromising your phone’s photographic abilities.

The main camera

Apple

So what has changed then? The major hardware change Apple made to the iPhone 18 Pro is the addition of an adjustable aperture to the main 24mm equiv. camera. Unlike the fixed aperture lenses that all previous iPhones have used, this allows you or the phone’s software to choose whether it wants to cut down on the amount of light hitting the sensor, or make adjustments to the depth of field without resorting to software tricks. And if you stop it down all the way, you can even get some sun stars.

The six-bladed aperture has four settings: F1.48, F1.8, F2.8 and F4. Notably, the brightest aperture is faster than the lenses used on the iPhone 17 and 16 Pro, which were fixed at F1.78. While I’m on record saying that an adjustable aperture probably won’t be a ground-breaking change (something I still generally believe), I caveated that statement with the assumption that the phone’s maximum aperture wouldn’t change. At the time, I thought the feature would make for a lens that goes from F1.78 to F4, or F6.1 to F13.7 equiv., letting you switch from a setting with enough depth of field to more than enough. But the difference should be a bit more noticeable now that you’re starting at F5.1 equiv.

Tucker Bowe

While Apple says the sensor behind the lens is new, details are light on what’s changed. It’s still the same size – Type 1/1.28 (71.5mm²) with 1.22µm pixels – as the one used by the 17 and 16 Pro, so it won’t gather any more light; the 50% improvement that Apple references in its presentation is entirely accounted for by the fact that the lens’s maximum aperture is half a stop faster.

Software

Apple

The rest of the camera improvements on the iPhone 18 Pro come from software, and many of the features are only available when using that upgraded main camera. The biggest finally comes from the the “Pro controls” mode, which lets you manually set parameters like white balance, aperture, shutter speed, and view a histogram. (Disappointingly, there’s no mention of manual focus control, for when the AF system doesn’t get things right. While this is theoretically something Apple could port to its older Pro phones, minus the aperture control, of course, its comparison page indicates that it has no intention of doing so.

Apple has also introduced a new “Reference” mode for the main camera, which it says bakes authenticity data into photos taken with the phone into the image on a pixel level. This appears to be an answer to Google Pixel’s inclusion of C2PA Content Credentials in its camera app, though its inclusion as a separate mode means you have to actively decide to use it.

The iPhone 18 Pro introduces Photographic Styles 3, an update to the system that gives you more control over what your phone’s photos look like, letting you adjust things like contrast and color at the point of capture. The system was majorly overhauled with the iPhone 16 Pro, giving you a lot more control and letting you change the style after-the-fact, rather than permanently baking it into the image. The version on the 18 Pro is a much more minor change, adding the ability to “customize texture and grain to soften skin details or achieve an artful film look.”

Finally, Apple is adding a “Smart focus tracking” mode, which will attempt to recognize and stick to a subject after you’ve tapped on it to focus. Again, this feels like something that could come to previous models, but Apple’s comparison tool says it won’t.

Video

Many of the iPhone 18 Pro’s video upgrades are the same as they are for stills: you get the benefits of the variable aperture, and the ability to manually control it and other parameters, along with the tracking autofocus.

Otherwise, the changes are relatively minor: you can now record at up to 4K/60 in the “Cinematic” video mode that adds simulated background blur, where the iPhone 17 and 16 Pro max out at 4K/30. More importantly, though, is that you no longer have to make the on whether to apply the effect or not when recording; you can apply it after the fact. The timelapse video feature is also upgraded to 4K, and Apple appears to have improved its noise reduction as it claims the 18 Pro has better low light video across the board, including on the selfie camera.

The rest

Apple

Of course, a phone isn’t just a camera, and Apple’s made some big changes under the hood that make the iPhone 18 Pro enticing even if you’re happy with your phone’s photos. You can read our launch coverage for the full story, but the top-level summary is that the chip is now substantially faster (especially when it comes to AI tasks, with twice the number of neural cores), and is kept cool thanks to a more advanced vapor chamber design, and some clever engineering choices. The battery life has also gotten a relatively impressive bump, and you can new refill it faster with 60W wired charging, where the 17 Pro topped out at 40W.

You will, however, pay for all these upgrades, in more ways than one. The iPhone 18 Pro and Pro Max start at $100 more than their predecessors for the same spec, and, while they keep roughly the same dimensions as past Pros, are the heaviest ones yet, despite their aluminum, rather than stainless steel, frames. That metal is, however, once again in four colors: black, burgundy, silver and a light blue.

Earlier this year, we reported on a novel photography contest sponsored by Icelandair: a competition to identify the worst photographer it could find, offering a free trip to Iceland and $50,000 cash. The premise was that Iceland is so beautiful that even a terrible photographer could capture its stunning landscapes, and Icelandair wanted to prove it. 

It turns out the airline got a much bigger response than it anticipated, receiving 127,642 entries from 178 countries. That’s a lot of bad photographers, and to find the winner, the judges spent more than 2,000 hours screening what were, by all accounts, terrible photos. You can’t make this stuff up.

Fast forward to June, when we reported on the winner, 28-year-old Blanche Mortemard of Paris, France, who wowed the judges with her inept technical ability and lack of compositional skill.

Blanche Mortemard

But the story didn’t end there. Shortly thereafter, Blanche jetted off to Iceland, presumably on Icelandair, to put her – ahem – skills to the test, spending 10 days touring the island and shooting its landscapes with no filters, no retouching and no AI.

The results are in, and while Blanche isn’t likely to be named photographer of the year by any other organization on the planet, she got some nice shots – along with less-than-perfect photos. As for Iceland? It understood the assignment and came through, looking beautiful, even if obscured by body parts. 

Blanche Mortemard

Reflecting on her experience, it seems that even Blanche thinks Icelandair’s marketing department was onto something. “Iceland makes it almost impossible to take a bad photo, despite my total inability to straighten the camera or take one without my thumb in shot,” she said.

And with that, the saga of one of the most interesting photo contests to cross our desks in quite some time comes to a close. Well, almost.

If you find yourself inspired by Blanche’s photography – and we’re not making any judgments – and are near London, you can attend the Iceland by the World’s Worst Photographer exhibition in person at White Rabbit Studios in Shoreditch on September 11 (2 – 8pm) and 12 (1 – 9pm). What’s more, you can attend a moderated talk by the “artist” (and we think even Blanche would use that term loosely) on Saturday, September 12 at 5pm. Admission is, mercifully, free, but needs to be booked. And if London isn’t on your itinerary, Icelandair says it plans to take the exhibition to a handful of other cities in North America and Europe. Because why not?

And let’s admit it – we probably all wish it could have been us on that trip.
