A while back I bought 89B filter(77MM) for my RB67. It is so dark I can't hardly see through it. Is this considered normal? BTW the filter wasn't cheap.

Yes. Hold it to a bright light and you'll see some red, but for practical purposes the filter should be opaque. And no, they're not cheap.

The filter is, for all practical purposes, opaque. they work best with a rangefinder camera. I feel that they are pretty much useless on an SLR camera, you just can't see what you are shooting.

I know what you mean, I usually take it off and focus and put it back on. Kind of pain in the neck, but I like it.

Yes, both 89B (695nm) or 88A (715nm) are "Black" IR filters. Best chance on a R.F. camera. I am using it (88A) on my C.V. Bessa III 667 R.F.

That's a funny way to spell "TLR".

I've never shot IR with an SLR, but I know people who do, and the workflow seems like a sort of "LF-lite": tripod mount, compose and focus, put the filter on, and then shoot. I suppose one could do the hyperfocal thing as well, or even just scale-focus given a sufficiently wide lens for that to be reasonable.
