Xiaomi Mi MIX 2S comes with 12MP dual-cam, OIS and 2x optical zoom

28 Mar

Earlier today, Chinese manufacturer Xiaomi unveiled its latest flagship smartphone: the Mi MIX 2S. Like with the original Mi MIX, one the new model’s most striking features is the large, almost bezel-less, display. However, the Mi MIX 2S has a lot to offer in the camera department as well.

The phone’s dual camera setup combines a main camera with 1/2.6-inch 12MP Sony sensor, F1.8 aperture and wide-angle 26mm equivalent lens with a secondary tele module, featuring a smaller 1/3.4-inch 12MP sensor, F2.4 aperture and equivalent 46mm lens for enhanced zooming and bokeh simulation. The main camera also boasts optical image stabilization, while the longer lens remains unstabilized.

Other imaging features include gyroscope-based Electronic Stabilization (EIS) in video mode, phase-detection autofocus and a dual-tone LED flash. And, of course, there’s a front-facing camera as well: a 5MP sensor behind an F2.0 lens.

The Mi MIX 2S is also one of the first devices to deploy Qualcomm’s latest Snapdragon 845 high-end chipset. In combination with 6 or 8GB of RAM, it should provide plenty of power to run the Android 8.0 operating system and apps. Between 64 and 256GB of internal storage mean there is plenty of space for image and video files, but unfortunately, an expansion slot isn’t on board.

A 5.99-inch IPS LCD display with 2160 x 1080 pixel resolution is available for general operation, as well as framing and editing of images. The 3,400 mAh battery should hopefully get you through a day of normal use.

The Xiaomi Mi MIX 2S will start at CNY3,299 (approximately $ 530 USD) for the 6GB+64GB version, and goes all the way up to CNY3,999 (approximately $ 640 USD) for the top model with 8GB RAM and 256GB storage, making the new model look like a good value proposition when compared to competing devices from more established manufacturers.

The phone is set to launch in China starting this April, followed by international markets sometime later. Unfortunately, chances we’ll see the Mi MIX 2S in the United States are slim judging from the push-back Huawei has faced while trying to break into the US market.

Nokia 8 Sirocco features 2x optical zoom and Carl Zeiss optics

26 Feb

HMD Global has today launched the Nokia 8 Sirocco. The Sirocco is the new top-end model in the Nokia line-up and comes with a range of improvements over the original Nokia 8 which was only unveiled to the public in September 2017.

The most important change has arguably taken place in the camera module. Where the old model combined an RGB with a monochrome sensor in its dual-camera setup, the Sirocco comes with a secondary tele-lens instead. The main camera features a 12 MP sensor with 1.4 µm pixel size and an F1.75 aperture. The tele lens offers a 2x optical zoom and has a 13MP pixel count and smaller 1.0 µm pixels. At F2.6 the aperture is slower as well.

Dual-pixel AF is on board, too, and, as before, the camera optics have been co-developed in cooperation with Carl Zeiss.

The Nokia 8 Sirocco is built for rough conditions. Its front and back are 95% covered by durable Gorilla Glass 5 and HMD Global says the metal body, which is hand-milled from stainless steel, is a lot tougher than its aluminum counter parts. The device is also water and dust resistant (IP67 certified).

Like the original 8, the Sirocoo is powered by Qualcomm’s Snapdragon 835 chipset and 6GB of RAM. 128GB of storage can be expanded via a microSD slot. The display has grown from 5.3″ to 5.5″ and uses now AMOLED technology rather than IPS, but the QHD resolution has remained unchanged.

The Nokia 8 Sirocco will be available in Europe from April for 750 Euros (approximately USD 920). Pricing for other regions has not been announced yet.

Trippy Tiles: Optical Illusion Installation Will Mess with Your Brain

14 Oct

[ By SA Rogers in Design & Fixtures & Interiors. ]

Looking at this picture, it seems pretty obvious that something is seriously wrong with the floor… right? And yet, as we should all know by now, things aren’t always as they seem, no matter how hard our brains try to reconcile the fact that a flat surface can look so believably sunken on one side. It’s kind of hard to wrap your mind around the fact that the effect is achieved simply by warping the shape of the tiles as they’re applied to the floor.

The new entrance floor at Casa Ceramica #Manchester now try and process that this floor is actually flat!! #tile #floorporn #decorporn #decor #tileporn #architectureporn #tiles #trippy #tilelove #love #lookbook #lovetiles #largeformat #largeformattiles #decor #design #detail #designer #decorporn #illusion #instagood #interiors #innovation #illusionist #ihavethisthingwithtiles #ihavethisthingwithfloors #roomdecor #roomforinspo #lovetiles #architectureporn #alice #aliceinwonderland

A post shared by Casa Ceramica Tile Company (@casaceramicatiles) on

Casa Ceramica Tile Company created the illusion for the entrance to their own showroom in Manchester, UK. People must have had a hard time believing that the tiles are really flat from initial photos posted to Instagram and Twitter, because the company posted subsequent photos and videos of the installation process, saying “Like our entrance floor made from tiles #sorrynotsorry.”

Apparently, the illusion only works from one direction, and when visitors are exiting the building, it looks like a normal tile walkway.

Unsurprisingly, the illusion blew up on Twitter and became something of an internet sensation. You might dig through the company’s website or Instagram hoping for more optical illusions, but it looks like most of their work is pretty standard. Maybe this project will get them some fun commissions.

OnePlus 5 2x tele camera uses 1.6x optical in combination with digital zoom

24 Jun

When we shot our sample images with the brand new OnePlus 5 we noticed that the dual-camera’s 2x tele-module did not quite deliver the pixel-level image quality you would expect from the 20MP Sony IMX350 sensor. Images showed low levels of fine detail and looked as if they had been upscaled which would point towards some form of digital zoom implementation.

This has now been confirmed by OnePlus co-founder Carl Pei in a tweet. He clarified that the second lens on the back uses a 1.6x optical zoom and that digital zoom is used to reach the claimed 2x zoom factor. The cropped image is then upscaled to achieve the specified 20MP image size.

The company says it is using its SmartCapture multi-frame technology to make the zoom “lossless” but arguably not everybody would agree with this term. Exif viewers show the focal length of the wide-angle and tele lenses to be 24mm and 36mm equivalent respectively which would mean a 1.5x zoom factor. However, there is a chance Exif isn’t taking the SmartCapture portion of the zoom into account.

Some other dual-cam implementations we have seen, for example on the iPhone 7 Plus are using a 2x optical zoom with a smaller sensor than the main camera. It appears OnePlus opted for the same 1/2.8″ sensor size in both cameras. An optical 2x lens would probably have required a thicker body or noticeable camera bump.

Optical Illusion Architecture: These 11 Buildings Are Not What They Seem

08 Jun

[ By SA Rogers in Architecture & Public & Institutional. ]

Pinched, warped, rippled, steeply angled and mirrored until they disappear into the sky, these buildings are not quite what they seem at first glance. Sometimes, it takes a nice long look at their outlines and proportions to determine where their facades actually begin and end, and how they can possibly be balanced so precariously.

Rachel Raymond Mirror House

In the space once occupied by the historic Rachel Raymond House in Belmont, Massachusetts, a beautiful mirrored illusion rose: ‘Mirror House’ by Pedro Joel Costa Architecture and design, which pays tribute to the original home’s modernism while looking to the future.

The Dancing House, Prague

Prague’s ‘Dancing House,’ also known as ‘Fred and Ginger,’ is actually the Nationale-Nederlanden building by architect Vlado Milunic, built in cooperation with Frank Gehry in 1996. One of the dual towers of the building appears to be warped and distorted, as if someone squished it up against the other.

Australian Customs Service Building, Melbourne

From most angles, it’s virtually impossible to tell what’s going on with the facade of the Australian Customs Service Building in Melbourne, clad as it is in an unusual graphic black and white pattern. The theme is reportedly repeated inside.

Pinnacle at Symphony Place, Nashville, Tennessee

The tall and thin mirrored Pinnacle at Symphony Place almost manages to disappear into the sky altogether when conditions are just right, becoming like a ghostly suggestion of a building instead of something decidedly solid and real.

Lucid Stead by Phillip K. Smith III, Joshua Tree, California

Alternating its logs with long stretches of mirror, artist Phillip K. Smith III makes his Joshua Tree installation ‘Lucid Stead’ blend with its environment so effectively it seems to be little more than a few dark brown lines floating in the desert.

Magic Ink: Highly Detailed Optical Illusion Drawings Pop Off the Page

03 Jun

[ By SA Rogers in Art & Drawing & Digital. ]

Strategically placed shadows and highlights make these incredibly intricate nature-themed drawings more than just impressive pages in an artist’s sketchbook. The pieces reveal unexpected depths and textures, and sometimes seem to lift right off the pages and into the real world, as if the sketchbook just couldn’t contain their vitality. Artist Visothkakvei shows off a variety of optical illusion techniques on his Instagram.

Fighting for the night. Once he's freed, the world will turn dark forever.

A post shared by Visothkakvei (@visothkakvei) on

Many of Visothkakvei’s works are contained within the bounds of his books. Though the drawings of flowers, leaves, vines and other organic subjects may look like simple doodles, it’s the way the artist layers them, packs them onto the page and adds shadows that makes them special. Some begin to creep beyond the boundaries of the paper.

Awaken #original #art #visothkakvei

A post shared by Visothkakvei (@visothkakvei) on

And, in some cases, it’s clear that more than just two-dimensional physical drawing is involved, though the artist doesn’t reveal his secrets. Some of this looks like he’s taken a photograph of his own hand working on the drawings, and layered digital drawing on top of it in a style that matches, making it unclear where the originals end and the digital additions begin.

Nikon centralizes optical engineering departments from across the business

04 Apr

Nikon Corporation has announced that it is to bring all of its optical engineering facilities under one roof with the establishment of a single division to service the needs of the whole organization. The plan aims to centralize the company’s optical skills from each of its business units so information, technology and knowledge can be shared to make the whole company more effective. The Optical Engineering Division will be under the control of the main Nikon company, Tochigi Nikon Corporation.

The creation of the new division is part of Nikon’s restructuring plan that has seen concerted efforts to streamline the business after its previous restructure didn’t produce the results it needed. Nikon says that optics are its principle strength and this reorganization will help it to make the most of its resources. There is also a suggestion that having all the optical engineering in one place will help the company respond to variances in demand for certain products, which may help to elevate shortages of new releases.

Press release

Establishment of the Optical Engineering Division, aggregating all optical engineering functions to create new value

Nikon Corporation (Kazuo Ushida, President, Tokyo) announced today that the establishment of the Optical Engineering Division on April 1, 2017. Aggregating all the optical engineering functions distributed in each division is intended to create a synergistic effect and enhance multifunctionality, as well as enabling flexible deployment of resources to the area as necessary so as not to miss any business opportunity.

This new Optical Engineering Division is an organization that aggregates lens, mechanical and system engineering functions related to optical equipment and optical solutions. Superior technology and knowledge with respect to optical engineering maintained in each division will now be accumulated and evolved in the Optical Engineering Division to develop optical products that create new value.

In our restructuring plan, announced in November 2016, we decided to restructure our group companies to enhance manufacturing technology of optical components that are our core competence and a differentiator from our competitors. All the functions related to the manufacturing technology of optical components, which were previously owned by Nikon Corporation and our group companies, have now been brought together at Tochigi Nikon Corporation, our consolidated subsidiary, which started operation on February 1, 2017.

In addition to these advances for manufacturing technology of optical components, the newly established Optical Engineering Division will further improve our greatest strength, optical technology, by aggregating optical engineering functions, thereby helping to maximize our products’ competitiveness.

Ask the staff: electronic or optical viewfinder?

12 Mar
Fujifilm’s X100 series, together with its X-Pro series, are the only models on the market to offer both an electronic and optical hybrid viewfinder. Is it the best of both worlds, or would you just rather have one over the other?

Believe it or not, as a team, we don’t all agree on everything. So at any given time, each of us thinks the rest of us are wrong about something subjective that you can’t really be wrong about (we’re all human). That takes us to the task at hand: all the great recent electronic viewfinders (Leica SL, Panasonic GH5, Fujifilm GFX 50S…well, some of us think that one’s just okay) got us on the topic of which type of viewfinder we prefer.

Optical or electronic? There’s no wrong answer. (Or is there?)

Richard Butler

For me, I’m less concerned about the technology behind a viewfinder than the quality of it. A good optical viewfinder can be a lovely thing: giving you a sense of being ‘in the scene’ that even the best EVF can’t match. A good optical viewfinder can also be excellent when shooting in very low light: its responsiveness and resolution don’t suddenly drop, for instance. However, on most cameras, you don’t get a good optical viewfinder. APS-C sensors tend to mean small, pokey little viewfinders and most focus screens for modern cameras aren’t very good for manual focus. So, if an EVF means I can have a smaller camera with a larger viewfinder, the ability to preview the effect of my settings and the ability to shoot video, then that makes up for many of the shortcomings. It’s impossible to separate the viewfinder type from the style of camera it allows and, with the quality of the latest EVFs, the style of camera I like most usually means it comes with an EVF.

Depending on the situation, I could go either way on the OVF versus EVF question. If forced to pick one, I’d choose OVF because I find shooting through an optical finder offers a more pleasant and rewarding experience than using an EVF. I also personally find it easier to compose images through an optical finder.

That said, EVFs make properly exposing images much easier, and in a commercial application in which getting the shot is mission critical, I could make an argument that EVFs are superior. That said, it would be cool if more cameras offered both, like on the Fujifilm X100 series.

Dale Baskin

I can’t believe I’m about to say this, but I now lean toward using EVFs. I wouldn’t have said that a couple years ago because, until recently, EVFs on still cameras basically sucked. Today’s best EVFs still won’t fool my brain into believing that I’m looking at an OVF, but in many respects they better reflect the way I tend to shoot with digital. I love the ability to overlay real-time information such as histograms, focus peaking, and zebras, as well as being able to preview exposure adjustments as they’re made. (I may be showing some of my video bias here as well.)

Are EVFs good for everything? No. I still wouldn’t choose them for photographing sports or in situations that require rapid-fire burst shooting, but I suspect EVFs will get there at some point. Of course, the best of both worlds is a hybrid OVF along the lines of those on the Fujifilm X100 series. I love having a perfect optical image overlaid with the useful tools an EVF provides. It’s kind of like the peanut butter cup of the camera world – the two just go well together!

Sam Spencer

Optical. Optical optical optical.

Don’t get me wrong, there have been some nice EVFs. The GX8, particularly, holds a soft spot in my heart.

At the end of the day, however, I prefer an optical viewfinder over any EVF. With an EVF, no matter how fast the camera is, the light has to enter the lens, hit the sensor, get processed, reduced, rendered, and THEN makes it to the eye. There has been a lot of work to make this ‘lag’ imperceptible, but it will never be completely eliminated. I find when I’m using an EVF I struggle timing candid shots properly, usually resulting in half closed eyes or an awkward expression. Also, with motorsports there is a lot of panning, which can be difficult through an EVF.

Ideally, I’d own a D750 and X100F to get the best of both worlds, especially because AF-C through the X100F’s OVF works way better than it has before…

Carey Rose

I’ve grown to love electronic viewfinders, but if I had to choose, I’d pick an optical viewfinder any day. It’s the combination of low blackout on higher-end cameras, how I’m easily able to follow subjects during bursts, and just the immediacy of seeing things as they happen that chiefly appeals to me. Whether I’m shooting sports, an event, a wedding or even just a dog playing fetch, the experience of using an optical viewfinder is just easier for me, and being able to clearly see a scene in really low light is invaluable. There’s a lot to be said for being able to preview your results with an electronic unit, but I still enjoy that brief ‘moment of discovery’ when I see an image on the back of the camera. Plus, a good optical viewfinder almost by definition goes along with a good phase-detect-only autofocus system, which I still prefer, despite the camera used in the above photo.

Wenmei Hill

I am strongly, adamantly in favor of…both. I shoot differently depending on whether I’m using an electronic or optical viewfinder. With an EVF, I let the camera control more – I’m comfortable shooting in aperture or shutter priority and using exposure comp to adjust what I see in the viewfinder. I experiment more with presets and creative modes because I can see the effects immediately, and I like an EVF with focus peaking if I’m focusing manually. With an optical viewfinder, however, I’m more hands-on with the controls. I pay attention to what I’m doing with the camera and feel connected to the scene in a way I don’t with an EVF. If I had to choose one, I’d choose an optical viewfinder because it feels more natural and immediate to me.

Allison Johnson

Electronic. I like the ‘being there’ feeling of an optical viewfinder, but almost any camera with an EVF also allows for a easily legible level gauge, which is a must for me (plus any camera that lets you put a level gauge in the EVF will also let you put a ton of other information in there as well). I have a problem where I’m drawn to shots where a level horizon is critical, but I’m also useless at nailing a level shot without that gauge. So even though I like the experience of an OVF better, I tend to get more keepers with an EVF.

What about you?

So, dear readers, what do you prefer and why? Let us know in the comments, and happy shooting.

OPPO announces dual-cam 5x optical zoom technology for smartphones

27 Feb

OPPO is not showing any new smartphone models at the Mobile World Congress but, as teased last week, the Chinese company has announced 5x Dual Camera Zoom system for smartphones. The system uses a periscope-style design and fits into a module that is only 5.7mm tall. Light is diverted through a prism and into the dual-camera’s telephoto lens which is arranged at  a 90-degree angle to the accompanying wide-angle. By shifting the path of the entering light Oppo is able to achieve a 3x optical zoom which is combined with a proprietary image fusion technology for digital zoom. The end results is a total 5x lossless zoom factor. 

At longer focal lengths camera shake becomes more of a limiting factor which is why OPPO has also integrated optical image stabilization into the system. Both the prism and tele lens can sense vibrations and compensate for them in real time. The mechanism dynamically adjusts its angle at increments of 0.0025 degree and OPPO promises 40 percent better performance than previous OIS generations for stable shots even at the 5x zoom setting. 

OPPO has not provided any information on sensor sizes and apertures, which would be critical to the image quality of the system, but nonetheless the technology looks like a very innovative approach to zooming on smartphones and we are looking forward to seeing it implemented in a device.

Gionee M2017 comes with 2x optical zoom and 7,000 mAh battery

28 Dec

Gionee is a relatively new name in the smartphone world but the Chinese brand has already established itself in Asian markets and is growing quickly in the Western hemisphere as well. With a price tag of approximately $ 1,000, its latest model, the M2017, places itself firmly at the luxury end of the mobile device spectrum; but looking at the specifications, that seems justified.

The M2017’s headline feature is its battery. The engineers have combined two 3500mAh units to create a massive 7000mAh battery that rivals those on some tablets. Gionee claims the device offers  32 hours of talk time or 26 hours video playback on a full charge. Quick Charge 3.0 is supported as well.

The camera specs sound very interesting, too, although Gionee has not provided too much detail. For now we know that the device features a dual-cam with a 12 and a 13MP sensor. This combination allows for 2x optical zoom, like on the iPhone 7 Plus, or a 8x digital zoom. The front-facing camera comes with an 8MP resolution. 

The rest of the specification reflect the luxury price point as well. Images can be viewed and composed on a 5.7-inch dual curved QHD AMOLED display. In terms of memory, there are 6GB of RAM and 128GB of storage. Unfortunately though there is no microSD-card slot, and for some strange reason, Gionee decided to use the mid-range Snapdragon 653 chipset to power the M2017.

The device is made from premium materials, weighs in at 238 grams and, despite the massive battery, is 10.78mm thin. There is no information yet on international availability, but we’d certainly like to have closer look at that dual-camera.
