it gives the same basic look to images as the new(old design)
Lomo Petzval lens and the Petzval lens costs about $600ish now(without taking into consideration shipping and currency conversions).
Plus the Petzval lens is manual focus only, with an antiquated rack and pinion system(like they did it 150years ago), and has a system of aperture variation called the 'Waterhouse Stops'.
Which you slot into the back of the lens as needed.
The Waterhouse Stop system can be directly translated into modern English as:

Moral of the story is to enter into the arrangement with a Monty Pythonesque point of view;
always look on the bright side of .....
