Old lenses?

Lately I have been reading about old lenses and adapting them to modern cameras. It is something I wanted to try out for a while, just for the sake of it. I'm on Nikon though and that's not an ideal system for adapting old lenses. Because the bayonett-focal-plane-distance is rather long most lenses you adapt will not focus to infinity. You need an adapter with a corrective lense for that - which will most likely not benefit quality. Actually most people will say it will make it useless altogether.

What the heck though, I wanted to play around with that a little. So I got me a M42 Beroflex 135mm f/2.8 and a cheap Nikon-M42 Adapter with a corrective lens. For both I payed around 20€ in total ...

And yes, wide open it is super soft:

But stepped down to f/4 and f/5.6 it's actually pretty good, even with what I can only assume is a super cheap lens in the optical path:

And honestly, it is just kind of cool to go all manual. To focus manually, to have to turn the aperture-ring yourself ... it is kind of fun.

And it somehow looks cool as well:

So ... will I be using it? Like really? Probably not - but no money wasted here. And chances are I'm going to get me one or two more. You know - for the sake of it.
