Gary, I now understand why you use the 29 Filter.  I had a D30 which 
was modified by http://www.irdigital.net/ but this proved to be a 
disaster.  I sent that camera to Roger Salmon in the UK 
james.salmon@... and he did a great job.  He adjusts the 
focus of the camera to accommodate the filter used.  I was so 
impressed I p'ex'd the D30 for a D60 which has a Schott RG780 filter, 
which is equivalent to the Wratten 87.  I'm thrilled. Because I wish 
him well, and want other list members not to be disappointed with 
irdigital, I post Roger's contact details

His business is growing with many from the US choosing to have him 
modify their cameras.

I shoot landscapes and figure studies and can shoot hand held, with 
confidence on focus issues at any aperture as with a normal DSLR.
