there's nothing that approaches the wide angle of a 15mm lens on a FF dslr, although there will be many times as much resolution and detail.
Even with my medium format film camera with a .62 crop factor, there are no lenses that are as wide as a 15mm on a FF dslr.
I may be missing the point here but What about the 47 mm Super angulon XL that will cover 4x5 and is equivalent to a 15 mm, the 38 mm super Angulon will cover 6x9 and 6x12 and is equivalent to a 15 on those formats. I have used the 47 and 65 angulons on 4x5 and I love them. https://www.schneideroptics.com/ecommerce/CatalogSubCategoryDisplay.aspx?CID=168. and I would think that for using a Fotodiox adapter for stitching images. That the 38mm would be great at F22 it produces an image circle of 137mm that would approach 13mm equivalency.
