This reads to me like another attempt to maneuver out of a false argument.No, none of that is talking about the issue. Crop to the same number of pixels. Obviously using the appropriate lens length. I thought that with all the experienced people here that it was obvious, that it didn’t need explanation in detail. I suppose I was wrong.
An APS-C vs FF discussion is either about using the same focal length and to get more "reach" or achieving the same angle of view or depth of field.
Only the same focal length argument can apply here in our discussion. Especially if you were talking about "reach".
So everyone understood you correctly, especially @AlanF and @neuroanatomist.
But you are still wrong, unfortunately.
