I am currently using a Pentax 645 lens that I used over 20 years ago on my GFX-50S2.
Despite being a 35mm lens, it provides a wide field of view and excellent image quality.
Since lens conversion adapters are relatively inexpensive, having old lenses can
significantly enhance the value of a camera in this class.
"This is a time-lapse of Orion in the late night.
As the temperature drops during this season, it creates favorable conditions for
capturing constellations.
Even in an area with urban light, with some ingenuity, it's possible to capture images
like this."
"I was able to see the 'Stairway to Heaven' during the rare sunrise hours.
The weather is unstable; this morning, there was even a rainbow in the western sky.
It might deteriorate later in the afternoon..."
