Pentax DSLR Role?

If I am not going to sell the Pentax DSLR and lenses, I would like to get back to using them.  I made these test images at the 300mm focal length setting of the 55-300mm lens.  I continued using it as I had in the past, shooting raw files and then processing them in Lightroom Classic.

I wasn’t happy with processing them since my computer was really running slow thus dragging out the processing and seemingly taking forever.  After every movement of a slider I had to wait for the effect to take place.

The only good thing was being able to expand my photography beyond what I can do with the Fuji X100V.
