Flashback: Samsung Galaxy S4 zoom, the phone that was mostly a camera

pgangwani35

Back in the days before multiple cameras, before periscope lenses and NPUs, the only way smartphones knew how to zoom was digitally and usually with poor results since they had small low-resolution sensors (well, there was that one Nokia, but we’re not going there now).

The Samsung Galaxy S4 zoom opted for the classic approach to zooming – having a lens that can change its focal length. From the back, this device was nigh impossible to tell apart from your typical point and shoot camera.

From the front, however, it was clearly a Galaxy S4 mini. The S4 zoom is not the first phone-camera hybrid, it’s not even Samsung’s first. The W880 AMOLED 12M (just take a second to admire that name) was released in 2009 – a 3G phone with a 12MP camera on the back, complete with 3x zoom optics and xenon flash (and yes, an AMOLED screen). Then in 2012 Samsung revealed the Galaxy Camera, which ran Android, though it missed the “phone” part.

The S4 zoom from mid-2013 is one of the earliest Android-powered phone-camera hybrids. Modern social networks were still in their infancy (especially on mobile), but the advantage of coupling the superior image quality (and zoom capabilities) of a point and shoot camera with the app selection of a smartphone showed great promise.

Let’s see what we have to work with. The lens could sweep from 24mm to 240mm, 10x optical zoom. And it was a smooth transition too, unlike modern tele cameras with fixed focal lengths that jump between zoom levels and use digital zoom for the intermediate steps.

This is the feature that gave the phone its name and there are still no phones that can match its 240mm focal length. The Huawei P40 Pro+ is supposed to get there later this year, but it will have a much smaller sensor sitting behind that periscope lens.



What a difference 10x zoom makes

The Galaxy S4 zoom packed a 16MP sensor that was fairly large for the time, 1/2.33”. For comparison, the Galaxy S4 had a 1/3.1” sensor, the iPhone 5s a 1/3.0” sensor. The camera also benefited from Optical Image Stabilization, which was almost non-existent back then – the Nokia Lumia 920 released a few months before was the first phone to have it.

The Samsung also had xenon flash, a feature that phones evolved out of as they strove to be thinner and thinner. But that was not a concern for this phone, the mechanized retractable lens put a lower limit on how thin the device can be. It ended up 15.4mm thick (though, impressively, it was the same height and width as the S4 mini).


The Galaxy S4 zoom was not a thin phone

The camera interface was borrowed from the Galaxy Camera. It imitated the rings on a DSLR lens and it managed to be both intuitive and quick.

Actually, the phone had a lens ring of its own. It could be used to zoom in and out (strangely, it could not be configured to change the manual settings). It also served as a quick launch shortcut, letting you dial in a specific mode instead of digging for it in the settings menu.

You could change the lens aperture . It only had two steps, but that was still twice as many as most phones offered. At 24mm, you could set it at either f/3.1 or f/8.8, at the longest focal length of 240mm your choices were a dim f/6.3 and properly slow f/17.8.

Still, you had control over that, the shutter speed and ISO and so on. Samsung included detailed explanations in the menus to help newcomers. This was never going to replace a DSLR, but it made for a great practice camera.

If you just wanted to shoot on Auto, there were several Smart and Expert modes that configured the relevant settings and let you just enjoy the moment.
