I can not remove the native objective lens. I press the removal button, the lens is not removable. Lens is blocked.
Не могу снять родной объектив. Нажимаю кнопку снятия, объектив не снимается.
It is not simple. I have to unscrew the lens before. And I know how to unscrew. However, already half a year can not unscrew the push of a button. I can just strip the threads by following your advice.
