Camera comparison: iPhone 11 Pro versus Galaxy S20 Ultra -- Does zoom matter?

AppleInsider

Samsung's new Galaxy S20 Ultra makes some big claims about its new impressive camera system including a mind-blowing number of megapixels and incredible zoom. So how does that play out against Apple's months-old iPhone 11 Pro and iPhone 11 Pro Max in the real world? We pitted them against one another to find out.

The Samsung Galaxy S20 Ultra and iPhone 11 Pro Max

Many are already familiar with the trio of shooters affixed to the rear of the iPhone 11 Pro and iPhone 11 Pro Max. There is a 12MP ultra-wide lens, a 12MP wide lens, and a 12MP tele lens that allows you to take photos at 2X optical zoom and 10X using digital zoom.

We aren't going to wade through the deluge of technical details regarding the Samsung setup, but we should at least touch on the basics. There are, in total, five cameras on the rear of the S20 Ultra. A 12MP ultra-wide lens, a 108MP wide lens, a 48MP tele lens, and dual depth cameras.

A lot of benefits come from those different camera modules. For example, the 48MP tele lens helps take higher resolution zoom shots and combined with software, affords users the ability to zoom up to 100X. The 108MP wide-angle lens primarily also only shoots 12MP photos as Samsung uses pixel binning to combine multiple pixels to act as one.

Samsung has pumped the camera app full of features such as long-exposure night mode, food mode, Live Focus (Samsung's take on portrait mode), Single Shot, and a full 108MP high-resolution shot along with much more. Some of these features may be fun, but if they aren't practical or are rarely used, they shouldn't be deciding factors.

We will start the comparison with some simple images before taking a look at different effects such as portrait and night modes before looking at that tempting 100X zoom.

Capturing the moment

A good smartphone camera needs to be versatile enough to capture all different kinds of moments, at home or out and about.

This photo of long-eared pup Dublin highlights some of those subtle differences. The iPhone is a bit sharper and has more detail on the couch and the fur, likely due to Apple's Deep Fusion tech. But, the S20 Ultra has a better balance in its tone. Samsung's auto mode detection also seems to have identified it as a pet photo and has slightly blurred the edges of the image.

In the above coffee house condiments tray the iPhone did a much better job lighting the image and bringing out the subtle details.

The iPhone doesn't have a "food mode" like the S20 Ultra does, so this isn't an entirely fair comparison. But you can see the sandwich shot with the food mode is quite saturated and has a blurred vignette around the edges. The iPhone image doesn't look nearly as colorful but the S20 goes so far as it almost looks fake, or at least overly edited.

Portrait mode

On the iPhone, portrait mode has become a favorite. In the above image of a gnome, both phones seem to do a good job with the rough edges. The iPhone did apply superfluous blur to some of the beard whereas the S20 Ultra kept it sharp -- but at the same time the S20 lacks much background blur.

In our second portrait and Live Focus shot the degree of bokeh is easily apparent. The iPhone pulls off a much more natural bokeh and can be adjusted to be stronger or softer depending on preference. The S20 too is adjustable but not nearly as much the iPhone is.

Additionally, the various effects on the S20 are useless. They include a swirl and other gimmicky alterations to the background of the shot. Apple, on the other hand, focuses on artistic and subtle effects that mimic real photography studio techniques. We much prefer Apple's approach.

This stage light effect on Mosby creates a much more stunning image that making the background look like it is swirling in a circle.

Night shots

Another common type of photo users often take is night shots, or at least low-light shots.

This can be at home, like Mosby taking an awkward-looking nap, or walking down the sidewalk under streetlamps.

Samsung, as it tends to do, produces a more vibrant image, boosting Mosby's hair color. But there is also more grain in the image. Apple leaned towards a warmer white balance in this shot as well.

We took to the night sky for our next low light shot, shooting handheld. Our iPhone chose a three-second shutter speed while the S20 Ultra went with a seven-second. In this scenario, iPhone blew the S20 out of the water. The colors may be more dynamic with the blues and greens but was nothing like real life. The S20 image also is darker, grainier, and muddier than what the iPhone produced.

Following that, we wanted to see what each phone could pull of when mounted on a tripod. With a tripod, each phone is able to expand the exposure. Samsung was upped to 27 seconds while the iPhone maxxed out at 30.

Samsung's image was only slightly different than its handheld shot but the iPhone was outstanding. The stars were clear, the sky a stunning blue, and the clouds slightly blurred from the extended exposure. A real step above the handheld pic.

Zoom on a whole new level

Finally -- we get to the zoom lens attached to the new S20 Ultra. This is a 48MP sensor that can reach up to 100X between its massive megapixel count and software tricks.

The S20 Ultra can go all the way to 100X zoom and the iPhone is limited to a mere 10X.

Above, we have a 10X image on both phones. Both produce usable images but when you crop into those images you see how much grain and sharpening Apple is starting to apply.

100X zoom on the Galaxy S20 Ultra

When we max out at 100X on the Galaxy S20 Ultra, the image quality starts to fall off. We start seeing most of the degradation around the 30X mark. The images produced past that start to look more like rough watercolor paintings than photographs.

100X zoom on the Galaxy S20 Ultra

These images are in no way usable and come off more as a party trick than something practical. We could maybe see it justified as a telescope to look closer at something, but not to take photos.

Samsung could have stopped at 30X zoom and user would be happy. Prior to the 30X mark, the images look great. We easily see those photos besting the iPhone.

Summary

Each of these two phones takes some amazing photos. Many of the small details can be adjusted post-shoot such as the white balance or saturation.

Other issues are more difficult. Apple can't better its zoom without new hardware that can capture more light with a bigger sensor or a modest boost in megapixels that can be cropped in. Samsung has vastly improved the zoom capabilities on the S20 Ultra, even if the majority of the zoom is purely a gimmick.

Comparing the cameras on the S20 Ultra and iPhone 11 Pro Max

Apple's iPhone 11 Pro Max -- and iPhone 11 Pro that has the same cameras -- shine in much more practical areas. Medium to low light, night shots, portrait shots, and more came out better on our iPhone than they did on the S20 Ultra.

During our shooting, we also had some software issues with the S20 Ultra. It would lag at times and the phone would occasionally hunt for focus. This killed crucial moments when trying to capture an image and we missed shots while the focus was dialed in. Just as we saw with previous phones the S20 Ultra also liked to excessively smooth faces, causing them to look unnatural. Samsung has already promised software updates to fix camera issues, but how that actually plays out remains to be seen.

It is near impossible to defiantly say which camera is universally the better one, especially depending on what images you are shooting most often. You likely won't be disappointed with either but we find Apple's approach more well-rounded with more practical benefits over Samsung's latest attempt.

I'd like to see some examples of the 30x zoom on the Samsung, just out of curiosity. The 100x just seems extreme. Like Samsung did it just to put a large number in their marketing materials.

One thing I notice a bit with Portrait Mode is the background frequently does not get blurred when it is visible through something in the foreground. For instance, if I take a Portrait Mode photo of someone who has their hand on their head with their elbow out to the side the background that is visible in the roughly triangular shaped hole between their body and their arm is not blurred while the rest of the background is. Sometimes this is almost unnoticeable but most of the time it stands out.

Noteworthy that the food picture from the iPhone looks much better than the "food mode" pic from Samsung.

Yes. A comparison of the maximum optical zooms would be great.

iPhone pictures are better than Samsung.

The 2 are close enough that it’s personal preference for taking basic shots.

There needs to be motion shots + zoom, otherwise the comparisons just look like ads for both phones.

Does the iPhone automatically detect that it is mounted on a tripod to up the exposure time to 30s? Do I need to use some setting for it?

Another query I had was, is the iPhone 2x Zoom lens a fixed lens or a moving one? When zooming between 1x and 2x, is it optical? Seems like a silly question, but I was always curious about it.

There seems to be a basic difference between the White Balance on the 2 cameras.

IMHO, it only really matter to the 'spec junkies' out there. The S20 gives them 'spec bragging rights' over the iPhone.

We all know at least one of this sub-species. If it isn't the phone it is the BHP and/or 0-60mph times for their car or the range and accuracy of their rifle etc etc etc. These people quickly get boring to be around.

I learned years ago to just ignore them and carry on with what I liked.

Overall, while there are some S20 shots that looks better, I prefer the iPhone's pics.  They seem less processed (even though I know that's not the case) than the S20's.  I can apply whatever processing I want later.

Yes, the iPhone will detect when it's on a tripod. When you see the Night Mode feature come on automatically, you can tap it and it gives you longer exposure times you can select. Handheld, the longest is 10 seconds. When the iPhone is on a tripod, exposure options will be up to 30 seconds. 

The zoom lens is fixed because two different lenses are being used between 1x and 2x. 1x is the main lens and 2x is the telephoto lens. So going between 1x and 2x is optical but lens isn't moving to zoom in since it's two different lenses.

Across the reviews of these two phones, all the photos are showing the same things:

- The high megapixel counts aren't delivering any benefit.
- Even the most generous, cherry picked examples of 100x, all look like crap. It won't let you read far away text or see additional details and the scaling is poor in comparison to professional tools.
- S20's images are over-sharpened, falsely saturated and have artificially boosted exposure. Psychologically this makes the user think the images are clearer. In reality it means:

1.  The midtones are missing and there are unavoidable hot spots and dark flat areas.
2. There is an introduction of excess colour noise/fringing.
3. Dark and grey objects receive unexpected colour tinting.
4. Images are unpredictably warm or cool.

Politely I'd label the S20 a mess, below amafessional and designed entirely for the ignorant.
Additionally if Apple released such a "100x" camera, they'd be sued for false advertising.

In the PowerPC days Apple told us about the “megahertz myth”; is it time they started telling non-technical users about the “megapixel myth”?

That’s been known for a while. There are compromises when increasing the pixel count of a ccd imaging chip, so more megapixels is not automatically  better

Ditto - as I scanned through the article, I looked at the pictures and decided which one I liked best before reading the description. In all except one I preferred the iPhone pic. 

I agree that it would be nice to see a comparison of 10x, 20x or 30x pics as that’s one point where Samsung may have an edge.

Not at all. With what is currently being done with smartphones, the extra pixels are reporting huge benefits to many handsets.

It looks like Samsung has software issues in this particular case and has promised that updates are coming. It might be worth revisiting the results after they roll out a couple of updates.

Other phones with higher megapixel counts actually have proven their worth and  themselves as the leaders of the smartphone camera pack.

Phone modes are sometimes tied to user preferences. Obviously a food mode is one such example. If you wanted your food to look like it really is, you would simply take a regular photo of it. If a dedicated food mode is in use, it is to inject certain characteristics into the image. Those characteristics are typically tuned to the phone makers home markets and Asia in particular has a penchant for pumped up colours.

In my experience with these modes (Master AI in the case of Huawei) every photo that uses it includes a label and touching that label cancels the effects that are applied.

In the case of extra zoom, it is universally accepted that more is better (especially when the max is x2), but that the further you go, the lower the resulting quality. That means that between x2 and x100 there is still a huge space to get great photos and that is where phone cameras have been going for the last three years: versatility. Getting something decent or great against not getting anything at all. Hence, more cameras and more modes.

I think we'll have to see if the software updates Samsung says are coming, do the trick or not.

Now if either company could just figure out how to not have a fugly camera bump...

Oh, wait, they both know EXACTLY how to do that.  And it'll have the added bonus of letting them use a bigger battery.

(Thicker phone, obviously.  It's time.  Be courageous, Apple.)
