Autism diagnoses have increased sharply in recent decades, leading to speculation that the condition is new or triggered by modern environmental factors. But a comprehensive review of research on autistic adults over the age of 40 paints a very different picture, showing that autism spans older generations, with as many as 90% of cases going undiagnosed.

Canon UK has posted a teaser on its Instagram account, saying that "something new is coming" and encouraging people to set a reminder to watch a YouTube livestream on September 9th at 3PM CEST (6AM PT / 9AM ET).
The teaser image is surprisingly revealing, showing what looks like a video-focused camera with a boxy design and potentially 1/4-20" mounting points on the top plate. It also clearly shows a red Record button in place of a shutter and a front-facing tally light.
The design is reminiscent of the EOS R50 V, an APS-C vlogging camera the company released earlier this year which featured a gimbal-friendly form-factor. However, given the several control points shown in the image and what looks to be a red-ring lens attached, it won't be surprising if this is a higher-end offering.
It's also worth noting that the announcement is set right before the start of the IBC (International Broadcasting Convention) trade show, where we typically get a look at company's video-focused offerings.
Whatever Canon has planned, it sounds like we won't have to wait that long to get more details.

In August, Nikon warned that it would be raising its prices in the US on September 1 because of the negative impact of tariffs. At the time, the company didn't specify which products would be impacted or how much the increases would be. Now, those new prices have taken effect.
This is the second time Nikon has increased prices in the US because of tariffs this year, though the first price adjustment only affected its lens and accessory lineup. The company's cameras were not impacted. Unfortunately, that's no longer the case. Most Nikon cameras are now more expensive, with an average increase of 8%.
September 1 price (% change) Original MSRP Z5 II $1847 (8.8%) $1697 Z7 II $2497 (8.7%) $2297 Z6 III $2697 (8%) $2497 Z8 $4297 (7.5%) $3997 Zf $2197 (10%) $1997 Z50 II $1007 (11%) $907The first price adjustment impacted Nikon's lenses, and some models received an additional increase with this second round. For example, the Nikkor Z 50mm f/1.2 S has gone from $2100 to $2247, and the Nikkor Z 14-24mm f/2.8 S from $2497 to $2697. The pricing change on Nikon's lens lineup was less significant than the pricing change on the camera bodies, potentially because those prices had already been increased once. Many of the company's budget-focused lenses did not change in price.
The company previously raised US prices across its lineup on June 23rd by an average of around 10%. Since then, the tariff situation has been in flux as trade terms were negotiated between the US and the various countries where Nikon makes its products.
Of course, Nikon isn't the only company that has adjusted prices. Over the weekend, Fujifilm also increased US prices, marking its second price hike within a month. Additionally, earlier this year, Canon, Sigma, Sony and Leica all marked up their products in response to tariffs. Thus far, of those companies, only Canon has made a statement about a potential second adjustment.
Viltrox is the latest company to be inducted into the L-Mount alliance, according to a press release from Leica. It joins the organization alongside other budget lens companies like Sirui and Samyang, as well as major camera manufacturers like Panasonic, Leica, DJI, and Sigma.
The announcement says Viltrox plans to use the mount "in future product development. " In its blog post, Viltrox says it plans to bring its AF 16mm F1.8 and 28mm F4.5 to the mount. The latter could be an exciting choice for owners of cameras like the Panasonic S9 or Sigma BF who have been looking for an ultra-small, lightweight prime.
Viltrox also says that those two lenses are "only the beginning" and that "more full-frame L-Mount lenses are already in development." However, the company doesn't mention when the L-mount versions of lenses will actaully be available.
That could be an exciting prospect for those who own L-mount cameras. The company is a rising star in the lens world; it gained its reputation largely thanks to its very affordable, but still decent lenses, but has since proven capable of making more premium options with its Pro and Lab series.
Press release:
Viltrox Joins the L-Mount Alliance and Utilizes the L-Mount Standard Developed by Leica Camera AG in Future Product DevelopmentTeaneck, September 1, 2025 – As a new member, Viltrox is the 10th company to join the L-Mount
Alliance since the public announcement of the L-Mount standard at Photokina in 2018. The alliance consists of founding members Leica Camera AG, SIGMA, and Panasonic, as well as Ernst Leitz Wetzlar GmbH, DJI, ASTRODESIGN, SAMYANG Optics, Blackmagic Design, and SIRUI. This collaboration enables Viltrox to develop products with the L-Mount which will present great benefits for a wide range of photo and video applications.
The L-Mount was developed by Leica Camera AG with the aim of providing customers with a future-proof, flexible, robust, and precise bayonet mount that would fulfil even the most demanding photographic needs. After its initial appearance, development of the L-Mount was continued by Leica as well as by its strategic partners. This led to significant improvements with new and more sophisticated L-Mount technology, resulting in a constantly growing portfolio of cameras and lenses from all existing and new alliance partners, currently comprising over 20 cameras and more than 120 lenses. All lenses made for the different systems within the L-Mount Alliance can be used on all cameras without adapters and without any functional limitations – this illustrates one of the numerous benefits of the common bayonet.
Valentino Di Leonardo, Managing Expert Technology & Licensing at Leica Camera AG: “The L-Mount Alliance has been a key pillar of Leica Camera AG’s strategy from the beginning, standing for openness, innovation, and the highest standards in photography. With its bayonet system, it offers outstanding flexibility across a wide range of photographic and videographic applications. By welcoming Viltrox as a new member, we are strengthening our network with a highly regarded partner that shares our vision of a forward-looking and versatile system. Viltrox contributes valuable expertise in high-quality lens development and brings fresh momentum to our ecosystem. Together, we aim to offer photographers and filmmakers an even more comprehensive and flexible system that meets the most demanding requirements.”
DAI JINHUI (Daniel Dai), CEO at Viltrox: “Viltrox has joined the L-Mount Alliance, further expanding the system’s reach with high-quality, versatile, and accessible lenses. This collaboration complements Leica’s portfolio by inspiring a new generation of creators – from passionate enthusiasts to seasoned professionals – while reinforcing a dynamic and inclusive ecosystem alongside alliance partners DJI, Panasonic, Blackmagic Design, and Sigma.”
About the L-Mount Alliance
The members of the L-Mount Alliance all utilize the L-Mount Standard developed by Leica Camera AG for mirrorless camera systems. Currently, the members of the alliance are Leica Camera AG, SIGMA, Panasonic, Ernst Leitz Wetzlar GmbH, DJI, ASTRODESIGN, SAMYANG Optics, Blackmagic Design, SIRUI, and Viltrox. The partners in the alliance utilize the L-Mount Standard for cameras and lenses that are offered under their own brand names. They market their respective products as competitors, and each with their own product and marketing strategies. The alliance works together on advancing the technology of the L-Mount Standard.
About the L-Mount Standard
To ensure maximum product diversity, the diameter of 51.6 millimeters was chosen to make the L-Mount suitable for use not only with full-frame cameras, but also on cameras with APS-C sensors. The short register of only 20 millimeters enables a short distance between the lens and the sensor, which in turn allows for a considerably more compact construction – which is particularly helpful for developments in the wide-angle lens segment. To ensure resistance to even the most extreme conditions and guarantee maximum reliability for many years of intensive use, the camera bayonets are manufactured from wear-resistant stainless steel, with four flange segments that prevent canting and ensure a secure and precisely positioned lens attachment. The standardized L-Mount contact strip facilitates trouble-free communication between the electronic components of the lens and the camera – including the possibility of installing future firmware updates for lenses to react to technological advances and exploit the full performance potentials of the lenses.

A tale of two coyotesA Tale of Two Coyotes by Parham Pourahmad, USA
Highly Commended, 11 – 14 Years
Parham Pourahmad (USA) uses the morning light to frame the amber eyes
of a male coyote within the black-tipped tail of a female.
Parham followed this pair – a female and possibly her brother – for a couple of hours across the rocky hillside, quickly framing his image before the male turned to nuzzle the female. Coyotes can adapt to almost any habitat and are abundant across North America and into Central America. Once common in San Francisco, they had disappeared from the city but are now beginning to return. While they do scavenge food waste, their diet also includes rodents and other small mammals.

Inside the packInside the Pack by Amit Eshel, Israel
Highly Commended, Animal Portraits
Amit Eshel (Israel) gets eye-level with an inquisitive pack of Arctic wolves.
In temperatures of -35°C (-31°F), Amit struggled to fulfill his dream of photographing the elusive Arctic wolves of Ellesmere Island. But then, on the twelfth day of his second trip, they came closer than he had ever imagined, so close that he could smell their breath. Restricted to Canada's most northern territories and northern Greenland, Arctic wolves are curious of humans due to a lack of interaction. They're a snow-white subspecies of the grey wolf, pack animals that hunt hares and musk oxen.

Pink posePink Pose by Leana Kuster, Switzerland
Highly Commended, 15 – 17 Years
Leana Kuster (Switzerland) shows a greater flamingo in the act of scratching its head with one of its unmistakably long legs.
While on holiday in southern France, Leana had been watching flamingos in the Camargue. She was fascinated by their foraging behavior as they moved gracefully through the shallow, saline wetlands, filter feeding for molluscs and crustaceans. Flamingos use their tongues to force water through their specially adapted bills, which are lined with many rows of fine, comb-like plates. These help trap a species of brine shrimp called Artemia salina that gives the birds their famous pink hue.

Rutting callRutting Call by Jamie Smart, UK
Highly Commended, 10 Years and Under
Jamie Smart (UK) portrays a red deer stag as it gives a mighty bellow during the autumn rut in Bradgate Park, UK.
Jamie walked up and down a path in the park at a safe distance from the stag. She stretched herself up tall to avoid any long grass in the foreground spoiling her view. The stag's antlers have regrown since their annual shedding in spring. The 'velvet' – the soft skin that covered them during their growth – has now rubbed off, exposing the bone beneath. Each new set grows larger and more complex as the stag matures, with more intricate points called tines crowning the heads of older males.

Ice edge journeyIce Edge Journey by Bertie Gregory, UK
Highly Commended, Animals in their Environment
Bertie Gregory (UK) freeze-frames the moment fledgling emperor penguin chicks walk along the edge of an ice shelf.
Bertie spent two months with the penguin colony and witnessed most chicks using ice ramps to descend to sea level for food. But this group missed the easy way down. Keeping his drone at a safe distance, he watched as they took a 15-meter (49 ft) leap into the water. Left to fend for themselves, emperor penguin chicks must find a way to make their first dip into the icy ocean to find food. Scientists believe the continued decline of sea ice in Antarctica may force more penguins to breed on ice shelves, making this behavior increasingly common in the future.

Deadly lessonsDeadly Lessons by Marina Cano, Spain
Highly Commended, Behavior: Mammals
Marina Cano (Spain) stumbles upon a group of cheetahs after they've caught a Günther's dik-dik in Samburu National Reserve, Kenya.
Marina watched the three young cheetahs practice their hunting skills while their mother looked on – a crucial stage in their journey to independence. The dik-dik was tossed into the air and killed just seconds after Marina took the photograph. Cheetah cubs spend their first two months hidden in a lair while their mother hunts. At around a year old, they begin joining her, learning how to stalk and which prey to pursue.

Slime family portraitSlime Family Portrait by Kutub Uddin, Bangladesh/UK
Highly Commended, Natural Artistry
Kutub Uddin (Bangladesh/UK) spots a line of alien-like slime moulds on a fallen tree.
Kutub found these blueberry-like spheres – the reproductive parts of a slime mould, each just 1-2 millimeters in diameter – in a nearby forest. His image resembles a fantasy landscape, though he describes the scene as a "bizarre family portrait," complete with a tiny yellow insect egg. A slime mold is a community of mobile single-celled, ameba-like organisms that live independently until they come together and work as one to find food and reproduce.

Jelly smack summerJelly Smack Summer by Ralph Pace, USA
Highly Commended, Underwater
Ralph Pace (USA) finds himself in the middle of a mass or 'smack' of Pacific sea nettles.
To try to protect himself from stings while taking this photograph, Ralph smeared petroleum jelly on any skin not covered by his wetsuit. The trailing tentacles can deliver a painful sting, which Ralph says feels more like that of a bee than a nettle. Highly adaptable to warming seas, jellyfish are appearing in larger numbers. Some biologists argue that more frequent smacks are a sign of rising ocean temperatures. The removal of predators and competitors through overfishing is another contributing factor.

Wake-up callWake-up Call by Gabriella Comi, Italy
Highly Commended, Behavior: Mammals
Gabriella Comi (Italy) witnesses a dramatic stand-off between a lion and a cobra.
Energy levels among the lions were low in the scorching midday sun. Gabriella and her guide, David, were about to move on when David spotted movement – a cobra was slithering towards two sleeping lions. Within seconds, the eldest of the pair was facing down the venomous intruder. Tanzania's Serengeti National Park is renowned for its large population of lions, with around 3,000 individuals living there. Lions are estimated to sleep for up to 20 hours a day to conserve energy.

Nature reclaims its spaceNature Reclaims Its Space by Sitaram Raul, India
Highly Commended, Urban Wildlife
Sitaram Raul (India) is among the chaos as fruit bats leave their roost in the ruins of a historical monument.
Working in total darkness, Sitaram manually focused his lens at the distance where he guessed the bats might appear, relying on his flash to illuminate the scene. All the while, bats were, in his words, "randomly pooping on me and the camera." Old World fruit bats are common across southern Asia. During the day, they roost in cavities such as hollow trees, caves and deserted buildings. Sitaram says that no matter how big our urban structures are, once we leave them, "eventually nature reclaims its space."

No place like homeNo Place Like Home by Emmanuel Tardy, France
Highly Commended, Urban Wildlife
Emmanuel Tardy (France) spots a brown-throated three-toed sloth clinging tightly to a barbed wire fence post.
Traffic slowed to a crawl as this sloth crossed the road, eventually reaching a fence post and gripping firmly. Concerned about not adding to the animal's stress, Emmanuel patiently waited for people to leave the area before quickly taking this photo. As their habitats become increasingly fragmented, sloths are forced to make more ground crossings to reach the safety of the next tree. In response, the Costa Rican government is working with local NGOs to establish biological corridors, including aerial bridges that reconnect their forest homes.

Toxic tipToxic Tip by Lakshitha Karunarathna, Sri Lanka
Highly Commended, Photojournalism
Lakshitha Karunarathna (Sri Lanka) reveals a solitary Asian elephant navigating a waste disposal site in Sri Lanka.
For over three years, Lakshitha has documented human–elephant conflict in Sri Lanka. This image is the result of months of meticulous observation at two open rubbish tips, where herds regularly forage. Around 20 elephants died over an eight-year period at a single site in Ampara after consuming indigestible food wrappers and other plastic waste. Alongside global efforts to reduce plastic use, conservationists stress the urgent need to secure landfills and prevent wildlife from accessing harmful materials.

Clouds of goldClouds of Gold by Jassen Todorov, USA
Highly Commended, Wetlands: The Bigger Picture
Jassen Todorov (USA) depicts the clouds reflected in salt ponds that span San Francisco Bay.
Flying his single-engine Piper Warrior into San Francisco International Airport, Jassen never tires of the changing colors of the ponds. On this occasion, he says, "the light during the golden hour, at sunset, was magnificent." The process of salt collection in the bay was industrialized in the 1800s. Since 2003, the South Bay Salt Pond Restoration Project has acquired 6,000 hectares (nearly 15,000 acres). By removing artificial dykes, the project is recreating tidal marsh habitat, allowing salt-tolerant plants and wildlife to flourish once more.

Fragile river of lifeFragile River of Life by Isaac Szabo, USA
Highly Commended, Wetlands: The Bigger Picture
Isaac Szabo (USA) watches longnose gars spawn in a crystal-clear Florida river.
Wrapping his feet around a drowned tree, Isaac photographed this female longnose gar with several males during the mating season. The presence of the turtle was, for Isaac, the "icing on the cake," as it "gives a sense of the whole ecosystem." This river is one of more than 1,000 waterways fed by freshwater springs renowned for their clarity. Maintaining the aquifers that supply these springs is vital not only for iconic wildlife such as manatees, but also for providing drinking water to nearly half of Florida.

Essence of KamchatkaEssence of Kamchatka by Kesshav Vikram, India
Highly Commended, 11–14 Years
Kesshav Vikram (India) expresses the character of the remote wilderness of the Kamchatka Peninsula in Russia's Far East.
Kesshav waited days for this image to come together: a brown bear strolling along the shore of Kurile Lake as the Iliinsky volcano emerged from the clouds. A slaty-backed gull flew past, aligned with the volcano's summit. Generally solitary, the bear was heading to feast with others on the glut of sockeye salmon migrating upriver to their origin lake to spawn. This caldera lake, formed in the crater made by a volcanic eruption, is the largest sockeye salmon spawning ground in Eurasia.

While machines have mastered both sight and sound, the sense of taste has proved harder to digitize. We've seen the creation of highly specialized artificial tongues targeting sweetness, chocolate, beer, wine or whisky, but now researchers in Beijing have developed a more generalist graphene oxide “tongue” that doesn’t just detect chemicals, it learns them. During laboratory tests, the system identified sour, salty, bitter, and sweet with nearly 99% accuracy, demonstrating that taste can be captured in digital form.
