The EXIF settings are below the image on the left side. The lens name is missing though, but just guessing from the entry for Maximum Aperture = 4.0, it could be a 35mm or a short zoom.
As Greybeard mentions, the low-res version as well as the larger version looks okay. Some things to note:
1.) The x and y resolutions are set to 72 dpi. On a computer screen which uses 96dpi or 120 dpi, you can run into some scaling issues from the monitor’s display algorithms that can make it seem softer than it is.
2.) You are shooting at f4, which does not have a deep depth of field such as what you may expect coming from cell phone cameras. What that means is that some parts of the image will seem soft or out of focus compared to others depending on the selected focus point — for example: the pen is fine, the letters seem soft. Try using f8 or f11 or even f 14 as a minimum for this shot and see if you get “sharper” images. Depth of field is an artistic effect that takes some getting used to.
HTH.
