I also think it would better fit into the calibration tag. Maybe this should be changed in the future. When the cropfactors and aspect tag is in the calibration tag we could also have multiple calibrations in one lens entry. Currently we sometimes have multiple lens entries in case of different crop factors. This could then be merged and made more simple. We could also add calibration data for RAW and JPEG in one lens entry. To be honest I never thought about this, but in the last weeks we had several comments and mails about that. I will create a feature request so it will not be forgotten. But as we are a quite small team it may take some time until a decision is made or until it is even implemented.
