Works.

There's only one problem with the algorithm for determining the lens
model (and it has nothing to do with your patch vs. mine): until
relatively recently, the LensModel wasn't in Exif.Photo.  In my case,
it wasn't until firmware 2.0 came out in 2012 that LensModel was
stored in Exif.Photo.LensModel.  Prior to that, it was in
Exif.Canon.LensModel.

I wonder if we need to do some kind of pattern match to look for
LensModel if we don't find it in Exif.Photo.
