The resolution of camera sensors is still increasing. Over the last decade it has grown from 3 megapixels to 50 megapixels and more. At first the increase in resolution was a significant one, but not anymore. Do we really need more resolution than the cameras that hit the market today?
When I bought my first digital camera, I had 3.5 megapixels at my disposal. It was enough for a nice 20×30 cm print with a good amount of detail. It was in a time when I used my camera just for holidays and memories. But when I started to take photography more serious again, I invested in an expensive 8.5 megapixel DSLR camera: the Canon EOS 20D.
The increase in resolution was amazing. Suddenly those 3.5 megapixels were a joke. Of course, the new camera was more than the increase in resolution alone. The camera was a semi-professional one, with interchangeable lenses, and the ability to shoot in raw format. All together it was a small step for mankind, but a huge leap for myself as a photographer.
From A High Resolution to a Higher Resolution
I think a lot of you will recognize this little story of my first steps in digital photography. For a few years I loved shooting with my Canon EOS 20D and I found out it was possible to print my work up to 1.5 meter wide without problems. Sure, when looking up close it was far from a sharp image, but from a practical viewing distance it was perfect.
As time went by, I bought a second camera, having 10 megapixels. Not a large increase, but still. I used it as my main camera, and the EOS 20D became the backup. Or secondary camera during weddings.
Eventually I got my hand on my first full frame camera; the legendary Canon EOS 5D. It had an amazing 13 megapixels, which was enough for even larger prints if necessary.
I think at about that time the megapixel race really started. High resolution became even higher resolution. There were 16 megapixels cameras, 20 megapixels, 24 megapixels, and eventually Canon introduced the first affordable 50 megapixel camera.
The Canon EOS 5s and EOS 5sR cameras aren’t the only ones now. Nikon and Sony have also cameras with similar resolutions. And a few years ago the first medium format cameras became relatively affordable, having 50 megapixels also. Fujifilm introduced the first real megapixel monster, called the GFX100, having more than 100 megapixels on the sensor.
Do You Really Need That Much Resolution
The Fujifilm GFX100 has a ridiculous amount of pixels. Shooting with that camera, that produces photos that measure 11,648 x 8,736 pixels, made me wonder for whom it’s made. Do we really need that amount of resolution?
Of course, the amount of detail is staggering. But it also imposes a few possible problems. First of all, it needs a lot of resources when post-processing those large files, being 200mb in raw format. Second, the amount of details makes it difficult getting real sharp results. Every little bit of camera movement while shooting will have an effect on sharpness. Also the auto focus has to be very precise. Fortunately, the camera has image stabilization, which will solve at least the unintended camera movement, but that is only part of a solution.
What Can You Do With Very Large Resolution Photos
A lot of megapixels must serve a purpose. If you shoot a lot of photos that are being used for really big prints, it might have a purpose. I am thinking about prints that are being uses as a wall paper, covering complete walls inside a home or office. Or perhaps billboards, the ones you always see from a larger distance.
To be honest, how often do print in such a large format? If you do, a large resolution camera may be the thing for you. But for most photographers a print of 50 x 70 centimeter will be almost the largest size. And for that you don’t need 50 or 100 megapixels.
Most of the time you really don’t need that amount of resolution. I guess most photographers won’t even print their photos. Or perhaps they will make a small album of their best work. Most images will end up being presented on a website or social media. So most images with very large resolutions will be reduced in size to fit the screen of a computer.
What Resolution Do You Really Need?
This is a question I can only answer for myself. It is very personal, and for my own needs. So I rather should ask: What resolution do I really need?
The answer still isn’t that easy to answer. I still shoot with a 16 megapixel camera, that has enough resolution for most occasions. But I rather shoot with my 30 megapixel DSLR camera, being able to crop a bit if necessary. When I tested the Nikon Z 7 and the Sony a7R III, I loved the amount of pixels, knowing it would be easier to print in large format with a wonderful amount of detail.
Also the Hasselblad X1D and Fujifilm GFX50 produced that very high resolution and it felt really good when I reviewed these cameras. But when I am shooting a wedding, I find this too much resolution. It has no use at all. Having between 20 and 30 megapixels is more than enough for these occasions. I think something like a 24 megapixels resolution is the best choice for most photographers today.
But What If…
There are also benefits having a high resolution. It gives the ability to crop the image without a significant loss. It isn’t a big deal when you loose 50% from a 50 megapixel image. You still end up with 25 megapixels. This is the main benefit for most, I guess.
On the other hand, if you shoot landscapes and you want the most detail available, a high resolution camera will give you just that. It may benefit your really large prints, but you won’t see this if you just show the images on the internet and social media.
In the end it is just personal, and you have to choose yourself if you need it. Perhaps you just want it, although it has no real benefit at all. And that’s okay also.
What I Want For Myself
Shooting with the Fujifilm GFX100 made me realize 100 megapixels has no real use for me. The images are huge. Fewer than 300 photos fit onto a 64gb memory card. I wouldn’t want to spend ten thousand euros on a machine that is amazing, but without a real benefit for me.
That is why I am very happy with my Canon EOS 5D mark IV, having more than 30 million pixels. It is more than I need, but it gives me the possibility to crop a bit if necessary. And in the rare occasion I need a higher resolution, I can always shoot a panorama.
What Do You Want?
I have a good idea of what is available on the market today. I have used a lot of different cameras with resolutions that varies from 8.5 megapixels up to 100 megapixels. For me I have an idea what the ideal resolution may be, as explained in this article.
But what do you want? What resolution do you need for your photography? Is it because you really need it, or because you just want it? I think there is no wrong or right answer, but I would love to hear your opinion about the best resolution for your camera. Please share it in the comments below.
