Hi,
I find that the zoom feature in Agisoft pro can be difficult to use when I zoom in very close to the model as the mouse controls (rotate, pan) seem to have a center of rotation that is not within the viewframe (hope you can understand what I mean). This results in the model 'disappearing' from the view frame with small rotations of the model.
I just tried Agisoft Viewer as I needed to share a model and was really happy to find that the zoom in controls work wonderfully! So my request is, could you port the Viewer Zoom controls over to Agisoft Pro?
