In 2019 the Huawei P30 Pro and Oppo Reno 10x zoom kicked off a zoom arms race with the introduction of the periscope telephoto lens – or should we say “re-introduction”. 1 phone had a periscope several years ago and with a design and style that was extra superior than fashionable phones.
At this time, you can get a periscope-equipped telephones from Huawei, Oppo, Samsung, Xiaomi, vivo and Honor. But they have two significant downsides. Just one, they have extremely very long focal lengths (100+ mm). And two, they are locked at that focal duration.
This suggests that mid-selection zoom calls for possibly electronic zoom with the main camera (the most common tactic ideal now) or a secondary telephoto module (an more and more well known choice). On the other hand, even with two tele lenses the hole amongst their focal lengths will have to be bridged by electronic zoom. What if you desired smooth zoom with out digital processing?
The alternative is to have a module with a variable focal duration. Previously this year O-Movie announced such a periscope, which could go smoothly amongst 85 mm and 170 mm. A pair of months afterwards Oppo unveiled its module that lined a a lot more conservative array (85mm to 135mm). We’re thrilled to see these two (and other folks) in smartphones upcoming 12 months. But we have to acquire a moment to recognize the phone that did it appropriate way back again in 2015.
That was the Asus Zenfone Zoom (available as ZX551ML in Europe). It had just one particular digital camera module and however its variable focal size periscope lens could choose broad-angle shots at 28 mm, portrait shots at 50 mm and zoom in to 84 mm (that is 3x optical magnification) and everything in involving. All without the need of a trace of electronic zoom.
The phone applied a module designed by Japanese organization HOYA and introduced in 2013. Tentatively named the “Cube”, this was advertised as the thinnest periscope module to date, measuring only 6mm in depth. This meant it could be used in rather slender smartphones – the Zenfone Zoom is 12mm thick, which seems like a whole lot but is rather slim in contrast to the 15.4 mm of 2013’s Galaxy S4 zoom (afterwards Galaxy camera modules were being even thicker).
This module housed a 13.1MP sensor, 1/3” in measurement, which was relatively normal for the time. For comparison, the iPhone 6S Furthermore had a 12MP 1/3” sensor, the Galaxy S6 went larger with a 16MP 1/2.6” imager.
The Dice module showcased Laser AF for speedy autofocus and optical impression stabilization (OIS), which is important for capturing at lengthy focal lengths. As we pointed out previously, the lens could stretch to 84 mm (in 35 mm equivalent) and open up to 28 mm on the extensive close.
That’s not much too poor, essentially, the P30 Pro has a 27mm wide lens and the Reno 10x goes only slightly broader with a 26mm lens. But the eager-eyed between you would have spotted an issue with the Zenfone Zoom. In fact, it is an issue shared by all telephoto lenses, periscope or otherwise.
The aperture is quite dim – only f/2.7 at the wide conclude. In 2015 the apertures of flagship phones were nearer to f/2., which seriously assisted with reduced-mild efficiency. The Zoom’s sensor was comparable in size to that of the Galaxy and iPhone, but the lens held it back again. In fact, assessments at the time pointed out that the Zenfone creates fewer than stellar nighttime photos.
Using a more substantial senor in a periscope layout is tricky as the thickness of the module is instantly tied to sensor measurement. And the Zoom was previously pushing the limitations at 12mm. The digital camera bumps on some 2020 smartphones are preposterous in dimensions, but even that may perhaps not be ample.

Furthermore, there is only so considerably a new lens design could do to widen the aperture, primarily now that f/1.7 lenses are reasonably common on the wideangle cameras. In other text, obtaining a digicam that handles the two large and tele focal lengths is not simple.
To be truthful, a single camera was the norm in 2015, it wouldn’t be until eventually the following yr (2016) that LG would show off the LG G6 with a broad + ultrawide twin set up. These days mutli-digital camera setups are the norm as they provide the most effective flexibility.
They definitely do. The wide cameras on modern day smartphones are wonderful and can defeat most digital cameras in the hands of a everyday consumer. A Zenfone Zoom type structure unavoidably sites limits on sensor dimension and aperture. The phone was forward of its time, but its time has handed – it is really difficult to have a one do-it-all camera and compete in high-quality.
Even now, when 2021 flagships are unveiled with huge angle cameras with enormous sensors next to variable focal duration periscopes, spare a moment to recall the ground breaking Zenfone Zoom.
By the way, this sort of lens can be noticed in some digital cameras. They have the advantage about traditional types in that the periscope is safely and securely housed within the device’s human body. This makes it possible for waterproofing and fall resistance to be extra. In contrast, common styles have greater optical attributes but are additional fragile, which is why we have only noticed them in a couple of oddball telephones like the Galaxy S4 zoom and a couple of other people. The Zoom was not waterproof, but it could have been.
The Asus Zenfone Zoom alone is a curiosity from a previous era and not just simply because of its digicam. It ran Android on an Intel Atom x86 processor, which would seem mad now that Apple dropped x86 in favor of ARM for its Mac computers and Microsoft is improving x86-64 emulation for ARM-based mostly Windows.
The crafting was on the wall even in 2015, as the Intel Atom Z3590 was exhibiting its age. Constructed on an aged 22nm procedure, it housed four cores functioning at 2.33 GHz and an Intel GPU at 457MHz (533MHz improve). The European variation of the Zoom got the Z3590 chip as a substitute, which elevated the CPU clock to 2.5GHz the GPU strengthen went up to 640MHz enhance.
Earlier Atom-run Zenfones were competitive in one-core performance – individuals CPU cores were being intended for laptops and have been larger than smartphone CPU cores, just after all. Even so, ARM chipsets advanced speedily and left the x86 at the rear of. In the smartphone type variable at first and now, most likely, in laptops as nicely.
Given that then Intel has abandoned its smartphone initiatives, phone chipsets went initially and much more just lately the modem division was sold to Apple. The enterprise is now struggling in the laptop and desktop markets as well, with AMD’s Ryzen demonstrating spectacular gains in functionality. But we doubt AMD will re-enter the smartphone business enterprise (as some of you may perhaps know, Qualcomm acquired the cellular Radeon division and scrambled its letters to come up with Adreno).
An additional now-exceptional characteristic was the leather again. This was manufactured from ox leather utilizing standard Italian tailoring methods to conform the leather-based to the milled aluminum body. These times vegan leather-based is more most likely to be made use of as an alternative.
The SIM-totally free selling price of the Zoom was just $400, whereas Android or iOS flagships have been in the $500-600 vary. Outstanding pricing contemplating the exceptional camera, but delays, constrained availability and insignificant advertising expending produced sure it hardly ever caught on with people and Asus in no way designed a sequel. So, this exclusive phone now lies typically forgotten.
