I've excepted that it won't show the lens data, it's really not too important and I can always find if it need be. However, it seems like Capture one never really wrote support for these files. It doesn't even know that they don't have color information. I'm guessing they never really added support for this camera, it works but barely. That really seems to be the achilles heel of this software in general, kind of scabbed together support for things and a high price to boot.
I'm going to play with it more but probably stick to my lightroom/photoshop workflow.
