While learning to take better photos with within the opportunities and limitations provided by whatever camera technology offers, it is also interesting now and then to stop to reflect on how things are evolving.
This weekend, I took some time to study rainy tones of Autumn, and also to hunt for the “perfect blues” of the Blue Hour – the time both some time before sunrise and after the sunset, when indirect sunlight coming from the sky is dominated by short, blue wavelenghts.
After a few attempts I think I got into the right spot at the right time (see the above photo, taken tonight at the beach of Hervantajärvi lake). At the time of this photo it was already so dark that I actually had trouble finding my gear and changing lenses.
I made the simple experiment of taking an evening, low-light photo with the same lens (Canon EF 50 mm f/1.8 STM) with two of my camera bodies – both the old, Canon EOS 550D (DSLR) and new EOS M50 (mirrorless). I tried to use the exact same settings for both photos, taking them only moments apart from the same spot, using a tripod. Below are two cropped details that I tried to frame into same area of the photos.
I am not an expert in signal processing or camera electronics, but it is interesting to see how much more detail there is in the lower, M50 version. I thought that the main differences might be in how much noise there is in the low-light photo, but the differences appear to go deeper.
The cameras are generations apart from each other: the processor of 550D is DIGIC 4, while M50 has the new DIGIC 8. That sure has a effect, but I think that the sensor might play even larger role in this experiment. There are some information available from the sensors of both cameras – see the links below:
While the physical sizes of the sensors are exactly the same (22.3 x 14.9 mm), the pixel counts are different (18 megapixels vs. 24.1 megapixels). Also, the pixel density differs: 5.43 MP/cm² vs. 7.27 MP/cm², which just verifies that these two cameras, launched almost a decade apart, have very different imaging technology under the hood.
I like using both of them, but it is important to understand their strengths and limitations. I like using the old DSLR in daylight and particularly when trying to photograph birds or other fast moving targets. The large grip and good-sized physical controls make a DSLR like EOS 550D very easy and comfortable to handle.
On the other hand, when really sharp images are needed, I now rely on the mirrorless M50. Since it is a mirrorless camera, it is easy to see the final outcome of applied settings directly from the electronic viewfinder. M50 also has an articulated, rotating LCD screen, which is really excellent feature when I need to reach very low, or very high, to get a nice shot. On the other hand, the buttons and the grip are just physically a bit too small to be comfortable. I never seem to hit the right switch when trying to react in a hurry, missing some nice opportunities. But when it is a still-life composition, I have good time to consult the tiny controls of M50.
To conclude: things are changing, good (and bad) photos can be taken, with all kinds of technology. And there is no one perfect camera, just different cameras that are best suited for slightly different uses and purposes.

As a final comment, I think that much of the blurriness of EOS 550D shot is also related to it being just slightly off-focus. There is huge difference in focus technology in these camera bodies. After using M50, it was really difficult to get 550D to focus properly, and the support for manual focus (“focus peaking”) was not there, so I was just left relying on my own, aging eyes in the dark…
I guess it is also about “dynamic range” that has a huge impact on digital photography. Digital camera censors have become better to capture details when there are huge contrasts between dark and light. James Popsys have an interesting YouTube post on this topic: “Dynamic Range – Does it matter?”.
BUT, in my opinion the shot taken with EOS 550D just is a darker exposure, and therefore less details for example on trees. I wonder if there actually are more details also on that shot if you try to adjust it lighter(?)
Sami, good comments, thanks. I certainly could improve 550D image further. Though, since there were all those focus issues with that camera (in low light, in particular), the raw material has its limitations. (I have to check that video from YouTube.)
