I have a catalog which listed plano convex cylindrical lenses. I am thinking to put it in front of 8mm Film and take hundreds of pictures on one roll. Catalog lists lots of lenses which focal lenghts starts from 3.9 mm and climbs to 1000 mm.

I want to know what images would like ? Some say for one axis , lens do not focus the light . Is it correct ? In that axis of evil situation , what the images looks like ? Completely blurred or half bokeh , half visible image ?

What do I need to make all axises focus the image ?

Thank you,
