This area of fat is aging your brain faster than others

Gizmag news -

While we've known for some time that obesity affects the brain, scientists have found that, more importantly, it's where you carry it that matters. And it's the deep visceral fat around organs that has the biggest impact on aging your brain, affecting areas of reasoning, memory and processing speed.

September challenge winners: These incredible photos were all taken with phone cameras

Digital Photography Review news -

The September Editors' photo challenge

The theme for our September Editors' photo challenge was "Pixels in your pocket."

We asked you to share images captured with the camera that's always with you: your smartphone, and the photographers who submitted photos clearly didn't "phone it in." Capturing everything from misty seasides to towering cliffs, in vibrant color and stark black and white, and from far corners of the globe, you proved that small sensors can tell big stories.

As usual, we were overwhelmed with great pictures – many more than we can present here. Our favorites, showcasing a diverse range of vision and talent, are presented in random order.

Thanks to everyone who participated in this photo challenge. If you want to participate in other photo challenges, visit our Challenges page to see currently open or upcoming challenges, or to vote in a recently closed challenge.

Picos clouds

Photographer: Jswell

Photographer's statement: This photo was taken while guiding a climb on Picos Urriellu in Picos de Europa National Park, Spain, on a post-storm morning – a combination of circumstance and position.

Equipment: Apple iPhone 16 Pro

Painting with light

Photographer: DerGatekeeper

Photographer's statement: At the “Zeche Zollverein” in Essen, Germany, there is a closed coal mine. The mining buildings are converted into a kind of industrial museum. The stairs have been illuminated with special lights, giving the scene an impression of being not of this world.

Equipment: Apple iPhone 16 Pro Max

The way up

Photographer: jaggedhorizon

Photographer's statement: I love skiing and skitouring just as much as I love photography. And the best thing is, being far away from the beaten path in the mountains, I can combine both, whether I carry a camera or a phone. I loved the simplicity of this image showing “skin tracks” and in the background, the Aiguille Rouge, near Arolla in Switzerland.

Equipment: Apple iPhone 15 Pro Max

Balloons over Myanmar

Photographer: light_reaction

Photographer's statement: This photo was taken while soaring above Bagan, Myanmar. This moment was guided by a UK army veteran piloting our balloon – a tradition in Bagan where British and international pilots work alongside local crews. Ballooning here is more than a visitor’s thrill: it’s a source of pride and support for the local community, with companies employing hundreds of locals and funding projects in education, health, and heritage conservation, ensuring that the ancient temples continue to inspire and sustain those who call Bagan home.

Equipment: Apple iPhone 8

Spiral spiral

Photographer: fatplanediaries

Photographer's statement: I spent a summer with family in Europe. At the time, I only brought a prime for my camera, so I ended up using my Samsung for all other focal lengths. My camera ended up becoming my B cam, as I enjoyed smartphone photography quite a bit that vacation.

Equipment: Samsung Galaxy S10 Plus

Blue is the color

Photographer: Briminkie

Photographer's statement: Breakfast in a Broadstairs hotel on a lovely September day. The man in the cap blended nicely into the frame, and all of a sudden, there was a David Hockney vibe.

Equipment: Google Pixel Fold

Vorderer Gosausee (Front Gosau Lake)

Photographer: supernaut

Photographer's statement: One stop to rest on a long mountain bike ride. This place is really a spot of beauty and helped to regenerate strength for the upcoming challenge.

Equipment: Google Pixel 9 Pro

Nakasendo phone booth

Photographer: slowscan

Photographer's statement: A solitary phone booth lights up a small section of the old Nakasendo, a historical road of 500 km between Tokyo and Kyoto, which passes through the mountains of Japan's interior. I took this photo while walking between Kiso-Fukushima and Agematsu, two towns that operated inns for travelers of this road in the Edo period.

Equipment: Apple iPhone 15 Pro

Picking up the moon

Photographer: Alisher Kabulov

Photographer's statement: This photo of a lone stork was taken in a half-abandoned village in Belarus. Admiring the sunset, the stork had no idea it had become a character in a tale of the stolen moon.

Equipment: Samsung Galaxy S23 Ultra

Tilt

Photographer: WarthFire GTX

Photographer's statement: There's a hill that I always climb during my lunch break, and I observed this condo and a tree on the hill. I just tilted the phone sideways so the tree appeared straight, and the condo tilted, to get this shot.

Equipment: Samsung Galaxy S22 Ultra

Værøy, Norway

Photographer: Markku H

Photographer's statement: This place is the Håen viewpoint on the island of Værøy in Norway. It is 438m above sea level. It had just snowed when we hiked to the viewpoint, which also made the place slippery and a bit scary.

Equipment: Samsung S25 Ultra

Breaking waves

Photographer: GeffBourke

Photographer's statement: This photo was taken in the early morning along the shoreline at Pacific Grove, CA. A storm was coming in, and the waves were magnificent, crashing onto the rocks.

Equipment: Apple iPhone 16 Pro Max

Frozen notes, Salida

Photographer: jaberg

Photographer's statement: "Frozen notes Salida" was made as my friend Lucy and I walked the town (Salida, CO) on a day that suddenly turned cold. Our newly purchased Melenzana jackets were conveniently stowed in the trunk of the car, and we were somewhat underdressed. Lucy, Minnesota born and bred, and an artist in her own right, shivered patiently as I worked the scene and ultimately composed this shot, bolstered by the promise of a warming stop in a local microbrewery as our next stop. There, with an eye to the incoming weather, we decided to stay the night in Salida.

Equipment: Apple iPhone XS

Milky Way over Monument Valley, Arizona

Photographer: philzucker

Photographer's statement: I stumbled out of my RV at around half past four in the morning at a campground in Monument Valley, Arizona, in May of 2024. We were scheduled to go for a sunrise tour. Looking up at the dark sky, I was suddenly wide awake; I saw the Milky Way for the first time in my life with my naked eye! I ran back inside my RV, grabbed my phone tripod, and made a couple of 4-minute astro mode exposures with my Google Pixel 7 Pro. This one came out the best, and only looking at the picture later, I realized that the rising sun showed its first dim rays exactly where the Milky Way rose. I have a large print of it hanging in my office.

Equipment: Google Pixel 7 Pro

Milwaukee Art Museum

Photographer: Mike Zweyer

Photographer's statement: I took this picture with a Motorola G4 in 2017. I didn't have a camera at the time, but I was always interested in photography. It all seemed so complex and complicated then, so I used my phone. I got a Fujifilm X10 camera not long after.

Equipment: Motorola G4

Chasing soap bubbles

Photographer: GiorgioDC

Photographer's statement: It was January 6, 2020, Epiphany, a beloved children's holiday in Italy, especially in Rome. I was in Piazza del Popolo with my three-year-old niece, who stopped, fascinated by the soap bubbles, trying to catch them. I was careful to hide the sun behind the obelisk and took the backlit photo.

Equipment: Apple iPhone 11

Alcedo atthi

Photographer: GinoSVK

Photographer's statement: “Rybárik” (a diminutive of fisherman), as we call it here in Slovakia, is returning to our natural landscapes nowadays. Fortunately, Rivers are cleaner, and awareness about preserving untouched riverbanks is growing. This particular photo was captured on the river Váh, which is the longest river in Slovakia and also the one that flows entirely within our national borders. Not long ago, I spotted another specimen deeper in the woods, beside a very small stream, likely thanks to the beaver colony there.

Equipment: Samsung Galaxy S24 Ultra

Diner

Photographer: Larry_T

Photographer's statement: I visit this diner often and had this photo in mind, sitting at the end of the counter. I used my iPhone 15 and took about 10 shots looking down the counter. The woman looking back at her friend breaks up the leading line of customers facing forward. I was fortunate to capture her eyes and expression.

Equipment: Apple iPhone 15

Pastel sunset

Photographer: Doc Hathaway

Photographer's statement: My wife and I were camping at Southwick on Lake Ontario and took a walk to the beach to enjoy the evening. Clouds were pretty thick on the horizon, so I didn't expect a great sunset, but they started to thin a bit as the sun was crossing the horizon.

Equipment: Samsung S23 Ultra

Carefree butterflies

Photographer: Frenchfx

Photographer's statement: I went fishing at this Bernheim Forest, Kentucky lake. I wasn't having any luck, then I saw these two butterflies hanging around this bush. I pulled out my Samsung S24 phone and had great luck. They didn't pay any attention to me at all. I walked right up to them, and they remained there flying all around the bush. The phone did a great job of freezing the action, too.

Stealthy off-road mini-camper van hails from unexpected US automaker

Gizmag news -

Out of the Big 3 US automakers, "Chrysler" is definitely the name that doesn't belong in a conversation about RVs and overland campers. Its siblings Jeep and Ram, sure, and competitors Ford and GM both offer RV-ready trucks and vans, but the actual Chrysler badge? No. That said, Chrysler was the one to introduce a new concept camper van at this year's Overland Expo Mountain West. The Grizzly Peak is a vision for a ruggedized everyday MPV that's as ready to camp on a remote canyon rim as it is to shuffle the kids off to baseball practice and dance lessons.

Earlier this week, we published our review of the Ricoh GR IV, a photographer's compact camera with an APS-C sensor. Alongside it, we uploaded a brand new sample gallery full of the images we'd taken during the review process.

That gallery is in addition to the one we posted shortly after we received the camera, which you can also view below. With this one, we made sure to include a few more examples taken using the camera's various color modes. There's also a wider variety of lighting situations and locations, as we took the camera to a few urban environments where it was more at home.

Heads up! TTartisan's autofocus 40mm F2 lens has arrived on L mount

Digital Photography Review news -

When TTartisan announced its AF 40mm F2 lens last month, the company teased that it would be available for L mount "soon." It seems like the wait is over, as the lens has now popped up on the company's site.

It's a particularly exciting option for L mount, as it's relatively light and compact for a fast, full-frame normal prime. It weighs around 167g (5.9oz) and is 44mm (1.7") long. That could make it a good fit for, say, the Panasonic S9, which could definitely benefit from a compact lens, especially one with an aperture control ring.

This is the company's second autofocus lens for L mount, following the 75mm F2 it released earlier this year. While it appears to be broadly compatible with cameras from Panasonic, Sigma and Leica, the company's site notes that it "does not currently support Leica SL3-S and SL3," though it doesn't explain why. While we don't suspect that many people are sticking a $170 lens on their $7500 camera, it does seem like an odd limitation.

The TTartisan AF 40mm F2 for L mount is available on the company's site and on Amazon. It's also available for Nikon Z mount and Sony E mount.

Professional milling machine for people who don't own forklifts

Gizmag news -

Precision milling has always been locked behind a "members only" sign – giant machines that take up massive warehouse space, cost more than your first car, and hum like an old air compressor 24 hours a day. For the average guy with big ideas, it's a sort of cruel joke: sure, you can design a million-dollar idea, but actually being able to make it? Now you have to hire a product development firm.

Panasonic Lumix 100-500mm F5-7.1 OIS samples and impressions

The Panasonic Lumix S 100-500mm F5-7.1 OIS is a relatively affordable new tele-zoom for L-mount cameras. We've borrowed a sample and had an opportunity to shoot a handful of samples with it at the local nature reserve.

Sadly there weren't many interesting birds around and the time we were able to visit, so we've ended up mainly with pictures of our favorite fallback waterfowl: ducks. There was a Belted Kingfisher, surveying the scene, but he seemed determined to only perch too far away to be photographed, even with the 1000mm reach of the new lens and a 2.0x teleconverter.

At 1285g, excluding the tripod foot, we found the 100-500mm to be pretty easy to hand-hold, and we probably would have been better off leaving the tripod foot at home. Panasonic gives a figure of 7.0EV of stabilization for the lens when combined with a Dual IS 2-compatible body, and we found it could be very stable. At the longer focal lengths, it's definitely worth setting the stabilization to 'Always' on, rather than 'On half-press' as you'll really need the stabilization to be working while you frame your shot.

We found it pretty easy to handhold, and we probably would have been better off leaving the tripod foot at home

The zoom ring is large and positioned so that the balancing point of the lens remains approximately within its limits, even when at 500mm, so you won't find yourself having to shift your hand further forward to full reach. It has a more than 90 degree throw, meaning you get quite subtle control over focal length, but you'll probably need to plan your starting hand position carefully if you want be able to extend all the way through the zoom range in a single pull.

There's a tension adjuster for the zoom ring, letting you determine how readily the zoom ring moves, but on our pre-production unit, the difference was pretty subtle.

We also shot it with the 2.0x teleconverter and have included a few examples. Before you attach a teleconverter, it's worth pushing the "Zoom Limit" switch into the On position. That way, once you extend the lens beyond its 150mm focal length, it won't then retract back any further than that point: preventing you from smashing the rear element of the lens into the TC.

It's worth noting that, while you can engage the Zoom Limit at any focal length, it doesn't like to disengage when the lens is set to 150mm, so you'll need to zoom in a little, to get the catch to release.

A 2.0x teleconverter takes the maximum aperture at full zoom down to F14, which can be a bit of a challenge, even in bright light, and in our samples it does rather unpleasant things to the bokeh. We found our S1R II remained at F14 (rather than its 'wide-open' setting), if you take the teleconverter off, so it's worth paying attention to this, if you're swapping it on and off a lot.

Still, even though 1000mm still wasn't enough to get a good shot of the elusive Kingfisher, we did appreciate that this is one of the more affordable ways to get so much reach on such a large sensor.
