Mainly, I am using three cameras (Canon EOS R6 Mark II, Pentax K-5 and Canon PowerShot G7 X Mark II) depending on whether usage of a DSLR is possible / allowed, or not.
Furtheron, I do have some more older cameras which I do not use anymore actively. Finally, there are the cameras which were used for making the pictures of this website but which I do not own anymore.
