Abstract
- Many smartphones now have extraordinarily sharp foremost digital camera sensors, rated anyplace between 50 and 200 megapixels. That is increased than what many professionals use.
- In actuality, these pixels are largely being put in direction of low-light efficiency and digital zoom, the latter coming with some critical drawbacks when you push it too far.
- A devoted telephoto digital camera will outshine any digital zoom so long as it has first rate specs. That makes it important to take a look at a telephone’s digital camera tech before you purchase.
Earlier than I used to be in a position to flip writing right into a full-time profession, I used to work as a part-time skilled photographer. I used to be hardly Richard Avedon, however I knew my means round studio lighting and a DSLR, and that was sufficient to get some work. I began with a Nikon D70, finally upgrading to a D300.
The D300 served me nicely till I offered it, but it was quaint by trendy requirements. It had a 12.3-megapixel sensor that was too noisy to make use of past ISO 1600, or typically simply ISO 800. Distinction that with my iPhone 16 Pro, which has a 48-megapixel foremost sensor, and might typically shoot in near-darkness utilizing a mixture of software program processing and optical picture stabilization. I might’ve killed for that after I was capturing wedding ceremony receptions. Right now, some telephones now sport ridiculously excessive megapixel counts that may’ve as soon as been thought-about state-of-the-art, such because the Samsung Galaxy S25 Ultra, which hits 200 megapixels.
Whether or not I am searching for phones or devoted cameras, nevertheless, I worth an extended telephoto lens much more than the sharpest potential foremost sensor. I will let you know why.

Is the iPhone 16 Pro worth buying for photographers and videographers?
Calling one thing Professional would not at all times make it skilled.
Why telephone makers emphasize sharper foremost sensors
It is about greater than bragging rights
Let’s take a step again for a second — what is the worth of an ultra-sharp foremost sensor? In spite of everything, the one in my D300 was ok to print 8×10 portraits. A 200-megapixel sensor can theoretically output 12,240 x 6,320 pixel decision, which is nicely past an 8K TV, not to mention a body you’d hold over your mantelpiece. Hypothetically, it’s best to shoot for a kind of billboards you see alongside the interstate.
The reply is that telephone makers aren’t actually after most decision. Relatively, they’re chasing two issues, the primary being gentle sensitivity. With bigger sensors, pixels will be “binned” collectively to enhance low-light efficiency. You quickly sacrifice decision, nevertheless it’s higher to have a usable 12-megapixel photograph than a loud, blurry 50-megapixel one. In well-lit situations, binning will be scaled again.
Telephone makers are chasing two issues: gentle sensitivity and a less expensive zoom impact.
Giant sensors are additionally an affordable means of attaining a zoom impact. Since a 4K picture will match right into a 100- or 200-megapixel one a number of instances, you’ll be able to typically crop-zoom whereas shedding little if any noticeable element. With software program processing, issues can doubtlessly be masked over.
Devoted telephoto cameras are comparatively tough. They not solely want a sensor of their very own, however an even bigger lens array that is tough to cram into the size of a smartphone. That is why many high-end units have huge digital camera bumps. As a consequence, “digital” zoom will be cheaper than the true deal, which is called optical zoom.

5 tips for phone photographers that make your pictures not suck
You are able to do rather a lot with a little bit when you assume like a professional.
Why execs go telephoto
With first rate specs, that’s
Discover that I stated massive foremost sensors allow an affordable zoom “impact.” The truth, in fact, is that you just’re simply blowing up a part of a extra distant picture. Meaning not simply potential element loss, however the magnification of any flaws, equivalent to sensor noise or mud specks. And the additional a picture is cropped, the extra seemingly it’s you are going to discover particular person pixels, because you’re working with fewer of them. You would possibly be capable of digitally zoom in on the tip of the Empire State Constructing from Hoboken, however the ensuing photograph will likely be a pixelated mess.
Digital zoom also can amplify any aberrations, equivalent to warmth distortion. Telephoto lenses are topic to those, too, however aberrations ought to at the very least be much less distinguished within the body.
You would possibly be capable of digitally zoom in on the tip of the Empire State Constructing from Hoboken — however the ensuing photograph may very well be a pixelated mess.
On prime of all this, there is a marked distinction in perspective with optical zoom. Telephotos are inclined to flatten a topic towards the background, and make it straightforward to realize shallow depth-of-field, at the very least when the topic is shut by. That is why portrait photographers usually use a 70- to 120-millimeter lens when a 50-millimeter one would hypothetically be ample. The outcomes are extra “creative,” for lack of a greater time period.
The asterisk right here is {that a} telephoto digital camera has to satisfy sure specs. Something beneath 12 megapixels is questionable, and even above that threshold, telephoto sensors are inclined to carry out worse in low gentle. That makes mechanical picture stabilization important — I typically get blurry photos with 5x zoom in well-lit situations.

Are you promoting your self brief with a 200-megapixel digital camera?
It is a matter of use instances
You are not essentially cursed when you’ve bought a telephone with a high-megapixel foremost digital camera however a low or non-existent telephoto. Relatively, it may depend upon how regularly situations fall outdoors the norm. Most images are typically shot inside shut vary of their topics, not more than a dozen ft away, and in moderately clear and well-lit environments. In these conditions, cropping to zoom is not a giant deal, since your telephone would not should blow issues up a lot if in any respect.
Ideally, telephone makers would offer the very best of each worlds, making lengthy telephoto cameras commonplace and beefing up their related sensors.
It is if you attempt to push the bounds that digital zoom falls aside. For instance you are attending a summer season music competition, however attempting to zoom in on a lead singer from the again of the group. You would possibly be capable of get a usable, high-resolution picture — however do not depend on it. Optical zoom is usually going to be extra dependable so long as the stage is correctly illuminated, you have bought sufficient zoom size, and you’ll maintain your hand nonetheless.
Ideally, telephone makers would offer the very best of each worlds, making lengthy telephoto cameras commonplace and beefing up their related sensors. That is little doubt coming sooner or later. For now, when you care about high quality images, I would recommend wanting into the precise digital camera specs of every telephone you purchase.
