You are certainly correct, Dave. And I for one praise your practical
technique. If you want light falloff, you need to get a Noctilux.

Right you are again, Dave. I actualy had to furnish proof that I had sold
all my tripods before my dealer would accept to sell me the Noctilux. He
also pays to have an assistant follow me around when I use it to insure
that I will only handhold the lens - I'm not even allowed to rest it on the
roof of a car or on a child's head as I make exposures of my fleeting
subjects against evenly lit, flat surfaces, the goal of which, of course,
is to make full use of the 3 stops of light falloff in each of the four
corners, which might otherwise go unnoticed.
