Hi, thanks for your considerations. Btw. mine isn't a scientific approach but, rather a practical one. I'm just sharing my experiences (thinking it could help other people, as other people's experiences helped me), so I don't fully understand your remarks.
Aren't the images enough to see if the lens works? Do you think I missed some kind of situation which could demonstrate better this fact?
Could you please tell me which one so... maybe I've shot it but not published... and can do it here....
