I am using Lightroom Classic and am trying to organise my photos into ultra wide angle, wide angle, telephoto, etc. I thought this would be easy by using smart collections. However, to get a consistent result I need to use Focal Length 35mm, but can only find Focal Length of the dropdowns for metadate filters and smart collections. Not all of my cameras have a crop factor in the Lightroom back database so not all convert to having a Focal Length 35mm. However, having some exceptions is better than no facility at all. Currently I am envisaging finding the crop factor for each camera, adding the information to a spreadsheet and calculating the Focal Length 35mm, and then assigning a keyword, such as ultra wide angle to group them together. Which is not very efficient.
