[Leica] WAS; UV filter and 21mm now 15 mm!

[Ted Grant <tedgrant@home.com>]

Here is a question regarding filter use. How would you folks handle this situation?

You just purchased the  Super-Elmar 15 mm f 3.5 lens for a cracking
$5000.US or higher. The front element stands out like a bulging bug eye
with funny looking cut away (more cut away) than covers by appearance
lens shade. How would you attach a filter, of any kind, to protect the
front element?  And not have it interfere with the viewing coverage.?

Seeing we folks always have such "wild and woolly" discussions regarding
filter use for protection I thought this might give it a slightly
different twist.  Hopefully this will create imaginative answers. And
please guys and gals, lets not get into semantics, nobody learns from that!
