Hi Marty,

I'm fully aware of everything you're saying. However, look at it from  
a hobbyist point of view. The UV-Nikkor and the Coastal Optics 60mm  
and 105mm UV lens would be really nice to have, but the cost is  
prohibitive for the casual shooter. The M8 offers a readily available  
alternative since so many of us own one. The cost is a couple of  
filters in addition to equipment we already own.  The very sensitive  
sensor makes it work even though the Leica coated lenses will cost  
you a few stops in sensitivity. While I have a specially modified  
Nikon D1X and use both enlarging and uncoated lenses with it, I find  
the M8 much easier to use and with useable sensitivity. I also find  
it is fun plus it satisfies my thirst for experimentation.

Cheers,
Len
