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. Colin
