Purchasing a digital lomography camera?

So i've been doing a little research, and I saw that in order to take lomo themed pictures, you need a lomography camera such as a 50mm or a 120mm camera.basically it requires film.

I have no issues buying film but the hassle of having to repurchase film, and making sure you have good images is something I don't want. I wan't to be able to take multiple pictures and not worry about if I'm wasting film or not.

Is there any detachable camera lenses I can put on a regular pro nikon camera to give it a really vintage lomo look or is there any lomography digital cameras I can purchase?

Any advice, I mean any! Would be amazing!

You can look at some of the offerings of Lens Baby

There are (or used to be) some adapters that allowed the plastic interchangeable LOMO lenses to be attached to a SLR or dSLR.

For clarity, LOMO cameras use 35 mm and 120 film (NOT 50 mm and 120mm) 120 film is actually 70 mm wide.
