In such cases, we must calibrate with the smalles possible crop factor (i.e. the largest image radius). Then, we add camera entries for all possible crop factors. But still only one lens model is necessary. At least in one case (I cannot remember the model name), there were different aspect ratios but the same crop factor. Then, the same camera and lens model can be used for all aspect ratios. (This is certainly something to re-visit for the next database overhaul ...)
