Worst ever seen Lens.

[charjohncarter]

Here is a photo made with a homemade lens that fits my LTM camera, so I guess it will work on M. It is an Instamatic lens mounted with the help of a plastic medication bottle in a LTM to T mount adapter. I, since this image was taken, have stopped it down 5.6 to lower the flare, (BTW it did not cost much):

A great way to do the above is to simply get an old junk-bin clear-ish filter, as cheap as you can find, then put it to the torture test as rxmd describes. You can get two and stack them to keep the vaseline from getting all over everything, and to hold a cardboard vignetting ring in place in the middle. (Or just use a step down ring with filters that are too small.) The nice thing about this approach is that you can try it on different lenses to see how the effect varies.
