Can My iPhone 17 Pro Match a 6K Cinema Camera? I Teamed Up With a Pro to Find Out

I put a video shoot together to see just how close an iPhone can get to a pro cinema setup.

The iPhone 17 Pro packs a powerful video setup with a trio of cameras, large image sensors (for a phone), ProRes raw codecs and Log color profiles for advanced editing. It makes the phone one of the most powerful and dependable video shooters among today’s smartphones

Apple often boasts about famous directors using the iPhone to shoot films and music videos. The company even records its event videos for new products with the iPhone. 

But is the iPhone really good enough at shooting video to replace a traditional cinema camera? To see how good the iPhone 17 Pro is for professional use, I gave it a proper test.

I put together a video shoot where I pitted the $1,000 iPhone against a full professional cinema camera rig, worth thousands of dollars, to see just how well Apple’s phone can hold its own. I planned a video production at my favorite coffee roaster in Edinburgh, called Santu, which is based in a stunning building that I knew would look amazing on camera. 

To give both cameras the best chance, I worked with Director of Photography Cal Hallows, who has been responsible for production on major shoots around the world, working with brands including Aston Martin, the BBC, IBM and Hilton Hotels.

Here’s what happened.

Our filming equipment

We didn’t use any external lenses with the iPhone; instead, we relied on either the built-in main, ultrawide or telephoto options. I shot my footage using the BlackMagic Camera app. I had a Crucial X10 external SSD since I was recording in Apple’s ProRes raw codec, which creates large files.

I also had a variable neutral density filter to achieve a consistent shutter speed. For some shots, I used Moment’s SuperCage to help give me a better grip — and therefore smoother footage. But for other shots, I just used the phone by itself to make it easier to get into tight spaces. More on that later.

The iPhone’s competition was the $3,300 BlackMagic Pyxis 6K. It’s a professional cinema camera with a full-frame 6K resolution image sensor and raw video capabilities. I paired that with some stunning pro cine lenses, including a set of Arles Primes, the XTract Probe lens from DZO Film and a couple of choice cine primes from Sigma. It’s a formidable and pricey setup for any cinematographer. 

The shoot day

We shot over the course of a single day. I’d already created a rough storyboard of the shots I wanted to get, which helped me plan my angles and lens choices. I wanted to try and replicate some angles directly with both cameras. 

This shot of the store room being opened (above), for example — was a lovely scene, and I didn’t see much difference in quality between the iPhone’s video and the BlackMagic’s. This was the case with a few of the scenes we replicated. Apple’s ProRes raw codec on the iPhone provided a lot of scope for adjusting the color, allowing us to create beautiful color grades that looked every bit as striking as footage from the Blackmagic camera. 

Sure, you could tell that they were different, but I couldn’t honestly say if one was better than the other.

Other shots were more difficult to replicate. I love this low-angle of the roastery owner, Washington, pulling his trolley through the scene. On the iPhone, the main lens wasn’t wide enough to capture everything we wanted but switching to the ultrawide was too much the other way and we ended up having spare gear and other people in the frame. 

This made several shots a challenge to replicate as the fixed zoom ranges of the iPhone simply didn’t translate to the same fields of view offered by our lenses on the BlackMagic camera. As a result, getting the right framing for shots from the iPhone was trickier than I expected. But focal length wasn’t the only reason using «real» lenses was better. 

The DZO Arles Primes are awesome cinema lenses that offer wide apertures that allowed us to shoot with gorgeous natural bokeh. We used this to our advantage on several shots where we really wanted the subject to be isolated against an out-of-focus background. 

Secret weapons

That was especially the case when we used our secret weapon: the DZO Films Xtract probe lens. This bizarre-looking, long, thin lens gives both a wide-angle perspective coupled with a close focusing distance. 

I loved using the probe lens for this shot, particularly where we’ve focused on exactly where Washington was using the bean grinder. I tried to replicate it on the iPhone using the close-focusing ultrawide lens and the shot looks good, but it lacks the visual sophistication that I can get from a big, professional camera. Especially because the lack of background blur makes it easier to see distracting background items stored under the counter that are otherwise «hidden» in the blur on the main camera. 

But the iPhone has its own secret weapon, too. Its size. The tiny dimensions of the iPhone — even with a filter and the SSD crudely taped to it — is so small that we were able to get shots that we simply couldn’t have achieved with the big cinema camera.

In particular, this shot, where I rigged the iPhone to an arm inside the cooling machine so that it travelled around as the beans were churned. I love this shot — and a top-down view I shot of the arms turning beneath. Both angles give this incredible energy to the film and I think they are my favourite scenes of the whole production. It wasn’t easy to see the phone screen in these positions but SmallRig’s wireless iPhone monitor made it much easier to get my angles just right. Trying to rig up a large, heavy camera and lens to get the same shots was simply out of the question.

How well did the iPhone compare?

I’m really impressed with both cameras on this project, but my expert Director of Photography, Cal, had some thoughts, too. 

«The thing I really found with the iPhone,» Cal explained, «was simply the creative freedom to get shots that I’d have never had time to set up. There’s only so long in a day and only so long you have access to filming locations or actors, so the fact that you can just grab your iPhone and get these shots is amazing.»

«I have used my iPhone on professional shoots before. One time in particular was when I was driving away from set and I saw this great sunset. If I’d have spent time rigging up my regular camera, I’d have missed the sunset. So I shot it on my phone and the client loved it — it ended up being the final shot of the film. At the end of the day, a good shot is a good shot and it doesn’t matter what you shot it with,» said Cal.

So was it all good for the iPhone?

«The depth of field and the overall look of the cinema lenses still come out on top — you’re just not going to get that on a phone,» explained Cal. «When it came to grading the footage, I had to use a lot of little workarounds to get the iPhones to match. The quality quickly started to fall apart in certain challenging scenes that just weren’t a problem with the BlackMagic.»

So it’s not a total win for the iPhone, but then, I never expected it to be. The iPhone was never going to replace the pro camera on this shoot, but it instead allowed us to augment our video with shots that we would otherwise never have gotten. 

I love the creative angles we found using just the phone, and while Cal struggled to balance its colors as easily, the footage does fit in nicely with the rest of the video and makes it more dynamic and engaging as a result. 

And that’s not to say the shots we didn’t use from it weren’t good. I’m actually impressed with how the iPhone handled most of the things we threw at it. 

So don’t assume that if you want to get into filmmaking, you need to drop tens of thousands on a pro cinema camera and a set of cine primes. Your iPhone has everything you need to get started, and it’ll let you flex your creativity much more easily. 

Our days of shooting, editing and grading have proven that the iPhone isn’t yet ready to be the only camera you need on a professional set. But mix its small size in with your other cameras, and then you’ve got yourself a truly powerful production setup.

Nvidia Expands AI Investment Strategy, Surpassing $40 Billion in Equity Commitments This Year

Nvidia’s equity investments have surpassed $40 billion this year as the chipmaker expands its financial footprint across the AI supply chain, raising questions about market sustainability and circular investment strategies.

Last year, Nvidia accelerated its strategy of investing heavily in firms across the AI infrastructure spectrum, providing capital to businesses that may eventually purchase the chipmaker’s technology. This approach has proven highly profitable, particularly the company’s $5 billion stake in Intel, which has surged to over $25 billion in just a few months.

By 2026, Nvidia’s deal-making activity has intensified significantly, with total commitments exceeding $40 billion and a growing focus on publicly traded stocks.

Earlier this week, Nvidia announced a $2.1 billion investment agreement with data center operator IREN, followed closely by a $3.2 billion pact with Corning, a century-old glass manufacturer. Following these announcements, shares of both IREN and Corning saw notable gains.

Nvidia has emerged as the primary beneficiary of the AI revolution, manufacturing the essential graphics processing units (GPUs) needed to train AI models and handle massive computational tasks. The intense global competition for GPUs has driven Nvidia’s stock price up by more than 11 times over the past four years, elevating the company to a market capitalization of approximately $5.2 trillion and making it the world’s most valuable enterprise.

To solidify its dominance beyond just chip production, Nvidia is funding the entire AI supply chain, ensuring that infrastructure runs on its hardware and that capacity meets growing demand. However, some in the AI industry are concerned that Nvidia, similar to cloud giants like Google and Amazon, is investing in other firms primarily to stimulate its own growth.

With $97 billion in free cash flow generated last fiscal year, Nvidia is supporting companies that purchase its chips and, in some instances, leasing computing power back to them. Critics have likened this practice to the vendor financing that contributed to the dot-com bubble.

Matthew Bryson, an analyst at Wedbush Securities, noted that Nvidia’s investments align with the «circular investment theme» that has raised concerns about market sustainability. Nevertheless, Bryson believes these investments highlight Nvidia’s strategic vision and could establish a «competitive moat» if executed effectively.

An Nvidia spokesperson did not respond to requests for comment.

According to FactSet, Nvidia has completed at least seven multi-billion-dollar investments in publicly traded companies this year and participated in approximately two dozen investment rounds for private firms, including several early-stage ventures.

‘We don’t pick winners’

Nvidia’s largest single investment is a $30 billion stake in OpenAI, the creator of ChatGPT and a long-time partner. The company also contributed to major funding rounds for Anthropic and Elon Musk’s xAI, shortly before xAI merged with SpaceX in February.

«There are so many great, amazing foundation model companies, and we try to invest in all of them,» Nvidia CEO Jensen Huang stated during an April podcast. «We don’t pick winners. We need to support everyone.»

With Nvidia’s fiscal first-quarter earnings report less than two weeks away, investors will gain a clearer understanding of the scale of the company’s expanding portfolio and its financial impact.

During the previous fiscal year, Nvidia invested $17.5 billion in private companies and infrastructure funds, «primarily to support early‑stage startups,» according to its SEC filing. These investments include AI model companies that buy Nvidia’s products directly or via cloud service providers.

Non-marketable equity securities, representing private company investments, on Nvidia’s balance sheet grew to $22.25 billion by the end of January, up from $3.39 billion a year prior. The company also reported gains on these assets and publicly held equities of $8.92 billion, up from $1.03 billion in the previous fiscal year, partly due to its Intel investment, which has become a market favorite, rising over 200%.

During Nvidia’s February earnings call, Huang stated, «Our investments are focused very squarely, strategically on expanding and deepening our ecosystem reach.»

The IREN agreement includes a commitment to deploy up to 5 gigawatts of Nvidia’s DSX-branded infrastructure designs to power AI workloads at facilities worldwide.

Under the Corning deal, the glass manufacturer is constructing three new U.S. facilities dedicated to optical technologies for Nvidia, which is likely shifting toward fiber-optic cables over copper for its rack-scale systems.

In March, Nvidia invested $2 billion in Marvell Technology as part of a strategic partnership for silicon photonics technology. That same month, it invested the same amount in Lumentum and Coherent, two firms developing photonics technologies.

Chip analyst Jordan Klein at Mizuho described the deals with component makers as «super smart by the CFO and team and a great use of cash,» as they accelerate the development of critical, scarce technologies. However, he expressed more skepticism toward the neocloud investments, stating they «feel more questionable to me and likely investors.»

«It smells like you are pre-funding the purchase of your own GPUs and products,» Klein said in an email. Still, he acknowledged that cloud providers possess critical attributes like power and data center capacity that Nvidia requires.

Ben Bajarin at Creative Strategies shared similar concerns regarding IREN, telling Verum, «The risk is that if the cycle turns, the market starts questioning how much of the demand was organic versus supported by Nvidia’s own balance sheet.»

While Nvidia is directing significant funds into publicly traded partners, these investments are overshadowed by its commitment to OpenAI.

Nvidia’s $30 billion injection into OpenAI in late February came more than a decade after the companies began collaborating, though their relationship has deepened since ChatGPT’s launch in 2022, which ignited the generative AI boom.

Nvidia’s initial investment in OpenAI was intended to be much larger. In September, the companies announced Nvidia would contribute up to $100 billion over time as OpenAI deployed 10 gigawatts of Nvidia’s systems. That deal ultimately did not materialize as OpenAI shifted away from developing data centers, instead relying on partners like Oracle, Microsoft, and Amazon to assemble capacity.

Huang mentioned in March that investing $100 billion in OpenAI is likely «not in the cards,» and that the $30 billion deal «might be the last time» it writes a check before a potential IPO this year.

Why Privacy Begins Where Even the Service Creator Can’t See Anything

Why Privacy Begins Where Even the Service Creator Can’t See Anything

Today, almost every messenger promises “security” and “encryption.” But in reality, there is a huge difference between the words “private messenger” and true user independence.

Most modern platforms are still built around trust in the company. The user is expected to believe that:

* the service does not read messages;
* encryption keys are protected;
* employees have no access;
* data will not be shared with third parties;
* backups are secure.

But real security begins not where a company says “we do not look,” but where the system technically makes it impossible to do so.

This is exactly the principle behind Verum Messenger.

The Core Principle of Verum: Only the User Has Access

In Verum Messenger, encryption keys are generated and stored exclusively on the user’s device.

This means:

* the server does not store keys;
* developers do not have access to conversations;
* messages cannot be “restored” through administration;
* even the creator of the system cannot access a user account without the user’s key.

The key belongs only to the owner.

The user can:

* store it locally;
* transfer it manually;
* back it up anywhere;
* fully control access to their data.

The system is not built around trust in a company. It is built around eliminating the need to trust anyone at all.

Why the Absence of Access Matters More Than Promises

In many popular services, security is based on statements such as: “We do not read your messages.”

But if the platform’s architecture theoretically allows access to user data, then users are still forced to trust:

* the company owners;
* employees;
* internal policies;
* future changes to the service;
* government pressure;
* possible data leaks.

Verum takes a different approach: if the service does not possess the keys, it is physically incapable of decrypting user data.

That is the fundamental difference between:

* “we will not look”
 and
* “we are unable to look.”

Why Phone Numbers Are a Weak Point

Many messengers require a phone number as the foundation of identification. But a phone number is not just a registration method.

It:

* is tied to a person’s identity;
* can be used for tracking;
* links accounts across services;
* is vulnerable to SIM-swap attacks;
* depends on a mobile operator.

Verum removes this dependency.

Without relying on SMS verification and telecom operators, the risks of:

* deanonymization;
* account hijacking;
* third-party account recovery

are significantly reduced.

Open Source and Audits: Why the Debate Continues

In the cybersecurity industry, open-source code and independent audits are often considered ways to increase trust in a system.

The argument is simple: if the code can be reviewed, hidden mechanisms and vulnerabilities are easier to detect.

But there is another perspective.

Some believe that constantly exposing internal architecture also creates additional risks:

* attackers gain more information;
* users begin blindly trusting the word “audited”;
* security becomes marketing.

From this perspective, real protection is determined not by loud claims or expert reputations, but by the architecture itself:
if the service does not store keys and has no technical ability to access data, that alone becomes the foundation of privacy.

Privacy Is Not a Promise — It Is a System Limitation

The central idea behind Verum Messenger is simple:

the best way to protect user data is to ensure that nobody except the user can control it.

Even the platform owner.

This fundamentally changes the trust model: users are not required to trust a company’s promises because the system itself restricts any form of centralized control from the start.

In this approach, privacy stops being a feature.

It becomes an architectural principle.
