I visited some similar telescope in Australia at https://www.sidingspringobservatory.com.au/ run by Macquarie University ... the students explained the lens system could not be too new and could not be too old. Basically it sounded like someone had partly reverse engineered one generation of the lens interface only.
I guess the camera and lens manufacturer wants their lenses to be used with their cameras and to have better results than other manufacturers, whereas random companies want to clone the interface and sell cheaper lenses that also work with the cameras. Realising how awesome the lenses are, the students want an array of them, however they don't have the budget to buy a similar array of top end manufacturers' cameras.
