So.......let me get this right (I will sit down first and think about it......)
DJI come up with a z-axis adapter specifically for the X5 camera to fit on the Osmo (different from the X3 Z-axis one).
It is designed, engineered and manufactured solely for the purpose of fitting an X5 camera (and lens) to the Osmo and smoothing out/absorbing the z-axis movement for this combination of equipment.
The only 'slight' problem is...... it doesnt actually work because the spring fitted from manufacture is too weak to support the X5 and Lens (or maybe even the X5 body only)?
However......if you chop 1cm off the spring (and presumably reform the end with pliers) putting it under more tension, then the thing does what it is supposed to do out of the box (but doesn't)?
Is that about right?
Surely, in any country this constitutes a product not fit for purpose and should never been allowed to make it to market?
Please show me where I can buy the X5 Z-Axis stabilizer, sir. I would be glad to order one, but I don't believe it's available yet. Which puts to rest the idea that this product is defective, as no one I know has one to hand.
