Compared to the various DSLR lenses in that focal length reach.

Just my opinion having seen many lens images of longer focal length they never seem to be as good as a telescope. One reason is they have many elements whereas a telescope only has 2 or 3 lenses. Camera lenses often have 13 elements most of which would be a basic type of glass.
The Pentax 67 300mm F4 EDIF was the closest to a telescope. Marco Lorenzi used one for quite a while very effectively but that was with a FLI Proline 16803 and a PME mount. An unusual setup but very effective.
