According to a report from , the Chinese smartphone company Xiaomi has patented three new smartphone designs with huge camera arrays developed in a collaboration with Samsung.
The three new patents were filed by Xiaomi Mobile Software in March of this year (2021) with the documentation on the patents published on June 11th. The first phone on the list seems to be the most advanced model with a design and is inspired by the Samsung Galaxy S21. The cameras sit on the top left of the device and stretch down nearly 1/2 the length of the phone. The camera lenses are stacked vertically with a narrow strip flash to the left of the stacked lenses.
The patent diagrams also indicate what appears to be a small microphone above the cameras on the back and has a center placed punch-hole camera on the front of the system. Interestingly, Xiaomi has also patented the back cover for this particular phone model that includes a long cut-out made to accommodate the larger camera system that protrudes slightly when compared to the rest of the back panel of the device.
The next device included in the patent documents displays a design similar to the Xiaomi Mi 11i with an oval-shaped camera island containing two large camera lenses and a smaller lens placed in between them. The rectangle on the design remains currently unknown but is likely to be either the systems flash or potentially a zoom lens of some kind.
The last model detailed in the patent documents shows a much simpler and familiar design, likely intended as a “Lite” version with the camera systems consisting of one large camera, and two smaller ones placed directly below the larger one. The flash for this system uses the elongated design placed beneath the camera island, and as with the other two models, there is a punch-hole-style camera on the front.
The remaining details on these three devices remain somewhat limited — the full Xiaomi Smartphone 2021 Patent document can be read at LetsGoDigital — and it is unclear when, or even if, Xiaomi will release these new phones since the company is rumored to be adopting an under-screen selfie camera design in the next wave of devices.

Within a few months of each other at the beginning of 2021, both Sony and Sigma announced 35mm f/1.4 lenses for full-frame Sony E-mount cameras. They were just begging for a comparison to be made. This is not the first foray into the 35mm f/1.4 landscape for either company. Sony had the Distagon 35mm f/1.4 […]
Within a few months of each other at the beginning of 2021, both Sony and Sigma announced 35mm f/1.4 lenses for full-frame Sony E-mount cameras. They were just begging for a comparison to be made.
This is not the first foray into the 35mm f/1.4 landscape for either company. Sony had the Distagon 35mm f/1.4 ZA available for full-frame mirrorless cameras since 2015. On the other hand, the Sigma 35mm f/1.4 DG HSM ART lens has an E-mount but functionally is the older DSLR design fitted with a non-removable converter. In both cases, the new lenses compared here are not updates, but completely original designs. Let’s take a closer look at the Sony 35mm f/1.4 G Master and Sigma 35mm f/1.4 DG DN Art to determine which new lens comes out on top.
Design and Build Quality
Looking at the lenses side by side, the most apparent difference in form would be that the Sigma is longer. In practical use, the extra length was never a problem in finding a spot in my bag or with handling. If you run a very tight photography setup with limited space and an extra half-inch here means taking away a half-inch of gear elsewhere, this might be a problem. For most of us though, it’s not a deal-breaker.
The same goes for the weight, where the Sony is a quarter-pound lighter. Like with the slight difference in size, the weight is not enough of a difference that I find could influence any purchasing decision on its own. I respect that the Sony lens achieves these marks, but at the end of the day, I can’t say it’s extremely important comparatively. We aren’t talking two inches and almost two pounds of difference like the Sony 14mm f/1.8 GM versus Sigma 14mm f/1.8 DG HSM.
Continuing the theme of non-difference makers, both lenses share 67mm threading for filters, meaning one won’t have any extra hidden ownership cost over the other in this area.
Both lenses feature the same set of controls including the focus and aperture rings, aperture de-click switch, focus hold button, and focus mode switch. The aperture ring can either be set to specific f-stop numbers manually or be controlled through the camera using the “A” setting.
Surprisingly, it’s Sigma that goes a step above here with the addition of an aperture locking switch. This prevents the aperture ring from moving off of the “A” setting, which avoids the scenario where the camera doesn’t want to respond to aperture changes and the photographer only later realizes the ring had mistakenly moved to manual. Points go to Sigma for thinking of this because it’s not uncommon for the aperture settings to get twisted while mounting the lens to a camera or throughout use when my hand works in that area while shooting.
Spending a couple of weeks with the lenses is not going to paint the full picture of build quality, but I did my best. Throughout my time on the island of Kauaʻi, I dealt with plenty of dust, rain showers, sand, wet surfaces, humidity, and sudden temperature changes. Even after the most trying conditions, there were no apparent ill effects on either lens. This is not to say nothing will develop over time, but they both seemed trustworthy enough to not baby around as far as my limited time could tell.
This is what it all comes down to. When I think about the differences between the Sony and Sigma 35mm f/1.4 lenses, and why someone would pay $500 more for the Sony, these are the three main reasons I can come up with.
The very first thing I noticed when shooting identical frames with both lenses is the distortion differences. In the example below, I’ve drawn a line above the horizon to more plainly see that the Sigma exhibits barrel distortion whereas the Sony is very well controlled.
Of course, barrel distortion is not the end of the world and can be automatically corrected while importing images to RAW processing software. I can spin an “advantage” to the Sigma in that it also gives more field of view to a scene over Sony. Say I’m photographing in a forest with no easily identifiable horizon line; it may be welcome to have more of the scene in my composition at the cost of distortion that no one can even tell is there.
Both the Sony and Sigma lenses have enough apparent sharpness that crosses the threshold of being good lenses to being great lenses. However, at the extreme edges of the frame with the Sigma, there is more of a drop-off of sharpness with photos taken wide open compared to Sony. The Sony lens keeps things together remarkably well. When stopped down to f/8 in the example below, both lenses are identical in sharpness.
Related to lens sharpness, I’ll add that when I compared vignetting, flaring, and color fringing, I found that all of these are equally well controlled. Jumping to the section below, you’ll find some ghosting and aberrations crop up in the Sigma f/1.4 and Sony f/8 images.
I also compared the out-of-focus qualities of these lenses. Both feature an 11-bladed circular aperture, which for quick reference is a step up from the 9-bladed aperture that their predecessors I mentioned at the beginning of this article used. More aperture bladed should mean even more perfectly circular bokeh with less noticeable straight edges, and that’s exactly what we get.
The difference I see is how defined the out-of-focus edges are. With Sony, the edges of the bokeh balls melt away and into each other. Sigma on the other hand has a more distinguished shape and each ball holds up as its own rather than smearing.
Honestly, it’s two different looks and I wouldn’t necessarily say one is better than the other. It depends on personal taste. If you like to shoot with out-of-focus lights in the frame, the Sigma might actually have more pop and more of a “wow” factor. That said, Sony’s lens will likely be a touch better at blowing out unsightly backgrounds into indistinguishable bokeh pudding and for that, I would consider it the more traditional winner in this area.
Neither lens totally blew me away in autofocus performance at f/1.4 when paired with the Sony a7R III. Both are perfect for less demanding autofocus needs like face tracking a person around the frame or Animal Eye AF for pet portraits, but when it came to tracking anything faster, neither performed well most of the time.
After tinkering away with my camera’s tracking sensitivity settings and seeing if the Sigma and Sony were just a little finicky on their preferences, I deemed both lenses equal in their autofocus performance when paired with the a7R III.
It’s a Good Year to Buy a 35mm Lens
At the beginning of this comparison, I wrote that the size and weight were nothing that distinctly made a winner, but throughout testing it was clear the Sony 35mm f/1.4 GM always had as slight of an edge as it did in those two physical categories. There was never any single area that instantly crowned it a winner, but Sony holds an edge nonetheless. It’s after compounding everything I threw at the two lenses that the slight edge-case wins added up.
Sony is the winner of this comparison, and I think it’s worth spending the extra $500 for it considering the lifetime of lens ownership.
But wait! It needs to be said that the Sigma 35mm f/1.4 DG DN Art is not bad by any means. I’m sure there will be some of you who will compare these two lenses and decide for yourself that the Sigma is still the better value, and that is completely reasonable. The Sony is my winner, but there was no loser.
Last week brought the debut of Hasbro’s new detailed action figures inspired by the characters of Ghostbusters: Afterlife. But the toy makers are also taking a cue from the Ghostbusters toys of decades ago by bringing back the Fright Features line. These action figures are geared towards kids by giving them cartoonish versions of both the classic Ghostbusters and the next generation from the upcoming Afterlife sequel. But that’s not all, because each of them comes with a unique ghost. Ghostbusters: Afterlife Fright Features Figures First up, the Fright Features line reaches back to the original 1984 film by giving us new versions of Peter Venkman, Ray Stantz, Egon Spengler, and Winston Zeddemore....
When you see as many Rolex watches as we do and have studied them for as long as we have, you start to recognize patterns. For instance, it’s hardly a shocker when Rolex introduces a new material option within a collection, or when the brand releases a fresh batch of references to accommodate a new generation of calibers. However, what is most surprising often lies in what is not currently available. Many of Rolex’s core watch models have been around for decades and during that time, they have been produced in numerous different variations. With that in mind, even after all these years, there are still a number of Rolex watches that still surprisingly don’t exist (yet). We originally published a version of this article back in 2019 and at that time, we were surprised that the Rolex...
A blocked milk duct can be painful. It can lead to a more painful and more serious condition called mastitis. Most women never experience a blocked duct or mastitis. Some women develop blocked ducts or mastitis more than once. If you are breastfeeding, you can’t completely eliminate the risk of developing a blocked duct or developing mastitis, but there are ways to reduce your risk that. Blocked Duct or Mastitis? A blocked or clogged milk duct is pretty much what it sounds like. The milk ducts are the tiny tubes that bring breast milk from the glandular lobules in your breast—where the milk is made—to the nipple, where your baby feeds. If these ducts become blocked for any reason, the lobules keep producing milk that has nowhere to go. The milk...
The first New Moon of the summer occurs today, on July 9th in Cancer. This luminary is asking us to embrace our amazingness and to own our power. The caveat is that we have to heal the past in order to create the present and future that we want. This lumnation directly aspects the planet Uranus, which is currently in the sign Taurus. Emotions will be excitable, yet tender — particularly towards the way we care for ourselves. The fixed star Wasat aligns with the New Moon and pushes us to augment our pessimistic attitudes or feelings, due to the presence of Uranus, who serves as a transformative source of energies. Chiron, the healing centaur, who is...
New Zealand Rugby has shifted game two of the Bledisloe Cup series against Australia north to their house of pain, Auckland’s Eden Park. The Wallabies will get two chances to break their Eden Park hoodoo this month after New Zealand Rugby (NZR) moved the second trans-Tasman clash from Wellington to Auckland. In response to New Zealand’s new border settings, New Zealand will now host back-to-back Tests at Eden Park – where the All Blacks have won 20 straight against Australia – on August 7 and 14. “Circumstances are out of our hands with what’s happened at the borders,” NZR chief executive Mark Robinson said. “That’s not something we have been able to influence.” The third and only Australia-hosted Bledisloe Cup Test in the three-match series...
As trends remain firmly on its side, Cloudflare () stock continues to climb. Since its brief pullback in early May, shares in the cloud-based cybersecurity company have rallied nearly 72%, from around $69 per share to around $118 today. But this could come to a halt once the company’s results for the second fiscal quarter (ending June 30, 2021) are released after the market closes on August 5. Why? Perhaps not due to the results themselves. Given the revenue guidance it provided for the June quarter, and its beat of analyst estimates for the March quarter, there may be a low likelihood it falls short of expectations. Yet after its strong run in recent months? Investors may decide to take the opportunity to “sell on the news.” This is not to say shares are set to go...
A blaze at an unlicensed HMO prompted officials to discover a dire lack of fire safety measures and the landlord to be prosecuted and fined. Eight people were believed to be living in the four-bedroomed semi-detached house in Uxbridge Road, Wexham, when an electrical fire broke out in one of the first-floor bedrooms in the early hours of 8th October last year, causing serious damage. An investigation by Slough Council revealed inadequate fire safety measures in the house including no fire alarms or fire doors. There was also a lack of safety features including a handrail leading to the attic room along with no safety certification of the gas and electricity systems. The was unlicensed, and an emergency prohibition order was issued preventing anyone living there until...
In a marked increase to the already-impressive production cadence at SpaceX Starbase, it’s all hands on deck with Booster 4 and Ship 20 preparations ahead of the duo being sent to the launch site. Booster 4 was stacked on Sunday, with all 29 Raptors installed by Monday morning. While the orbital launch attempt is not imminent, the duo is expected to undergo a series of ground testing objectives, including multiple Static Fire tests for the booster. This will also provide time to complete the final elements of the Orbital Launch Site (OLS), from which the duo will conduct the milestone test flight.Path to Booster 4/Ship 20: Following a short ground testing campaign with Booster 3, which included cryo proofing and a three-engine Static Fire...
