[QUOTE=asimov;968001]No worries. Actually reading back..You mention removing a filter, only one model has a filter & that would be the DFK..my mistake..Unless you are using a 1.25" IR/UV cut on the nosecone of the DMK & took THAT out/off....Nup, I'm still confused!!

Sorry John my goof,
It is a DBK21-618 and you were right I had an IR filter on the nose piece. I took it of to see what would happen. Just learnlng how to work the little sucker.
