On crop factor etc:

The only thing that matters is FL.
From there, anybody can calculate the scale of that particular lens, that means how many mm per arcsec. Or, how many pixels one arcsec uses at that particular sensor.

The FOV of the camera depends on the physical size of the sensor.

The so called "crop factor" is misleading term and should never be used, at least not among people who understand the basics of camera geometry. Because it was "invented" by some companies to make it simpler for people used to conventional 35mm film cameras.. thus creating only a confusion among other users.

To extend my point: What if someone is using Canon lens mounted on webcam? Crop factor is then 3, 4 or even higher, depending on the size of the sensor.. referred to 35mm film size, of course.
If someone is used to 22mm sensor (most cheaper Canons) , then crop factor relative from those is again different (1.6x smaller)..

In earlier days of astrophotography (when plates were used), the term used was "scale", expressed as arcsec/mm, as mentioned at the beginning of this post. It did not matter what size of film or plate was used, because this number was lens dependent, thus constant.
