Helicon FB tube

[Aqualife]

Hello. I am new here. Today I found Helicon FB tube on your website. It looks much better than the original focus stacking on the Nikon D850. Are there any experiences? How long has the product been on sale?

Unfortunately, for the time being we do not have experience of testing the d850 focus shift feature and can't compare with the functionality of the tube.
Sales of the tube have been launched in April 2017.
