LOL... "no lens"
“No lens” shots are used with lenses that don’t have a confirm chip. Lenses such as Rockinon, Bower, or Samyong are all manual focus lenses and don’t have contacts for canon bodies to know which lens is attached to the body. I believe the Nikon versions have them, Canon doesn’t.
I had a Bower 14mm and for some reason Lightroom identified the lens as a 50mm.
