Why a newcomer is challenging one of Sony's most interesting lenses

Over the past few weeks, lens maker Thypoch has been teasing the release of its first autofocus lens. But rather than entering the world of autofocus with a prime, as many of its peers have done, it's introducing the first China-designed and developed zoom for full-frame. And it's an F2.8 zoom, at that.
How has the company gone from making M-mount manual-focus primes to an F2.8 zoom for full-frame? Quickly, says the company's Go-to-Market manager, Xavier Luo.
"The project began at the end of 2024," he tells me: "and it's taken almost a whole year to make the lens ready for large-scale manufacturing."
"In China, this would be considered quite a long time," he says, when I express surprise at the short timescale.
I ask him to expand on why the company decided to jump straight to zoom lenses, and why this particular specification. "We are very good at making zoom lenses," he tells me: "we have a cinema lens background and already make dozens of [manual focus] zooms. Two times, three times, even ten times zooms for full-frame, APS-C and Micro Four Thirds, so we have a lot of experience."
"It's taken almost a whole year to make the lens ready for large-scale manufacturing"
And, there's a degree of pride at stake, too, he suggests: “There’s strong anticipation across Asian markets, with Chinese users in particular eager to gain a wider choice of lenses, because the Chinese brands’ prime lenses have become more and more competitive both in terms of price and optic performance. These people are hoping to get a some kind of zoom product in the market so that maybe people can buy a zoom lens with a prime lens price."
Why 24-50mm?
The company settled on a 24-50mm as its first product for a number of reasons, Luo tells us:
"We know it has a lot of controversial points." he says: "The core value of the zoom lens is zoom, right? So people are arguing [about] that in the Sony 24-50mm comments. But we noticed that people are getting more and more focused on a lightweight lifestyle in recent years. People are trying to get more lightweight cameras, lightweight bags and lightweight everything. A 24-50mm can cover the daily use, or for your travel."

The other critical factor was that they believed this range would let them make a better lens. "[we didn't want to be] too ambitious, and make a 24-70, that kind of zoom lens," Luo tells us.
"When making zoom lenses, the biggest difficulties is to have a well-controlled distortion and at the same time have a really good sharpness," he says: "We think making a 24-50 means we can control it really well both in terms of sharpness and other [factors, such as] spherical aberration and distortion."
Some of this comes from it taking a different approach: "If you shoot with the Sony 24-50mm original lens with in Raw you may notice that it has in-body distortion correction," he says: "Third-party zoom lenses can be limited by the body communication protocol."
"We think [Sony] has a more open attitude towards third parties"
"In-body distortion correction means you have a perfect JPEG file but you don't have that in the Raw file. So for optical designers, it gives convenience: they don't have to worry too much about distortion, and that's a big deal, because they have only focus on the sharpness side. But for us, it's totally different: our designers have to look at both factors."
"We asked Sony, but we didn't get any official confirmation," he tells us: "we actually want to pay the protocol license fee, but we couldn't get any official reply. We think they have a more open attitude towards third parties."
Challenges
We asked what the biggest challenge was of developing an autofocus zoom for the first time: the optical design or the mechanical design. "It's the physical design," Luo tells us: " more specifically, it's the software and electronic parts because in the autofocus lens domain, the level of the electronic and software decides the maximum optic performance in the lens."

"It's totally reversed, compared with manual lenses," he says: "with manual lenses, the optic performance leads the mechanical design. But, you know, [for autofocus] it's totally different: it depends on how much weight the lens motor can drive and the precision it can deliver."
The company developed its own STM motors for the task. "I think still 90% of lenses use STM focus motor," he says. The company spent a lot of time working on making sure focus speed was competitive, and that focus is precise and doesn't hunt in video. "we tested the autofocus precision in a lot of scenarios and to make sure [it performed well] whether people are using it for photography or video."
Internal zoom
As well as a design with no software distortion correction, there's another obvious difference between Sony's 24-50mm F2.8 and Thypoch's lens, despite the similar dimensions and weight: the Voyager 24-50mm is an internal zoom design.
This has a benefit beyond just retaining the lenses' compact dimensions, says Luo: "it's better for people who are trying to make vlogs or short video, when they are using the lens on gimbals or even if they are [working] handheld."
The logic of E-mount
For now, the company is focused on the E mount for two reasons, we're told: "We think Sony E-mount has the biggest user group, and [we think] this lens fits the Sony Alpha users' interests. But we are still waiting to see what's happening in this industry, but our focus is just on E-mount right now."
"Our focus is just on E-mount right now"
But also, given the recent history of other manufacturers taking non-licensees to court, "Sony has a more open mind for third-party lenses."
Thypoch hasn't revealed all the details of the 24-50mm F2.8 yet. It's already publicly teased that the lens is coming, and shown it at the NAB trade show in Las Vegas. We're hoping this means we don't have to wait too long for the rest of the details, including the price, to be made public.
"I think when we reveal the price, people will be surprised by the high quality performance ratio of this product."
