Same focal length, same speed, same film format, one lens is a zillion times bigger than the other.

Speaking of ridiculous things, there's always the Sigma "Green Monster"-- The 200-500mm f/2.8 lens that weighs 34.6 lbs, looks suspiciously like a high end refractor, and costs about the same as a small car.

Comes with a 2x teleconverter, hence the 1000mm on the display.
Does someone make an adapter for my Pentax Auto110 so I can use that?
 
Is the lens on the Nikon a contax mount lens with an adapter?
Or is it one of the lomography lenses?

There are a few 15mm lenses available for SLRs (there is a Pentax-A for sale in classifieds), and yeah they are huge
 
Weird. No wonder SLRs never took off.





An SLR requires retrofocus WA FL optics to leave room for the reflex mirror. The rangefinder can use not-reotrofocus designs since it has no mirror to leave room fo.

Anyone ever manage to adapt lenses to the Auto 110?

It's do-able. I assume it's been done. The aperture and the shutter are combined inside the Pentax 110 body -- and automatically control the exposure of the film.

Put out the bat signal and lets see if anyone bites.

We know. It’s about having some fun hence the statement “no wonder SLRs never took off”.
