Thanks all for the comments.
Now, last thing first: no, the lens is not relevant expect for the fact that is the lens that came with my first reflex (a Zenit 122 I bougth more than twenty years ago, thant still works and that I still use from time to time).
So it is just a "nostalgia thing"
About the cloning thing, I'm not sure I understand what exactly should I do (I'm not that good at cloning
)
By the way, feel free to try and post the results
And now, for something completely different*, another shot with the same lens (this time closed down, at last).
* that's not true, it's the same old stuff
