If DJI can make a 15mm clip on lens, surely they can make a 35 or even 50mm with the right optics? Are they testing the market with this 15mm and rolling out others in the future?

The issue I see is that the ND filters wouldn't work, so not great for film, but I'd gladly have these in the bag just in case.

Fuji x100 fixed 23mm lens , they developed a tele and wide lens, the tele is now 35mm but the weight of the glass needed was incredible for the tele, so I would think there may be real problems with weight on the gimbal , so I wouldn't  hold out much hope.

Hello there CloudVisual. Good day and thank you for sharing your valued insights with regards to this matter. I will cascade these information to the designated DJI department for further attention. Thank you.
