-------------- next part --------------
just did it....


I have a wonderful DR with absolutely great glass,  and a old rigid  
with exactly the same focal length inscription inside of each

ie. 51.9N...

identical...

so....
I unscrewed the nice lens cassette from the DR and placed it into the  
nice mount of the rigid...

et voila...c'est fait,

a perfect fit,

seemingly,

now to try it out on the M8, so stay posted...over the next day or  
two...

I will let you know...


thanks, Steve
