Greetings:
This may (or may not) be a silly question.
But I thought I would ask anyway.
I have a Petzval lens in magic lantern mount. It slides easily in the lantern sleeve using the existing worm gear.
However, I noticed the lens barrel is symmetrical and can be reversed. A simple procedure by taking out the pinion mount screws, reversing the barrel, and replacing the screws. Then the Petzval projection lens is in backwards.
So now to the silly question: I get great images looking through in either direction. To my eye they don't look much different. Has anyone done this and found any benefits shooting with the lens backwards?
And feel free to punish me if this is a truly idiotic question. But my inherent knowledge of Petzval design is essentially nil.
Cheers. Bob G.
