Awesome lens there, very good for portraits 
A new unit (body only) is around ~RM8050 or higher, so you can just try something around that range, or a bit lower to sell quicker 

I also have the takumar 50 f1.4. Adapted via a m42-nikon.
But, focus to infinity is not possible due to the distance between the sensor and the lens. I got myself the adapter with a glass in between adapter which allow to focus to infinity.
Bought from ebay.

Ah good. Does this seller also have the Konica AR-Nikon mount too ? 😅

Be aware that the addition of glass on the adapter will causes degradation on image quality if you buy a cheap adapter. Anyway nikon have tons of vintage lens like the non ai .ai, ais lens which I believe your camera can utilize very well. Just my 2 cent haha 

Here some info that require you heavy reading abit haha

Basically all nikon lens with F-mount should be no problem when mount on your DF camera except the nikon rangefinder camera lens that have S-mount which is totally different mount. So that mean most of the nikon lens should be mount on your DF camera and also have the camera light meter working which is great haha. You might find some good vintage lens at a good price at ebay like nikon 55mm macro f3.5, nikon 135mm f2.8 and much more. Oh no wonder why you have this kind of vintage lens. Yeah saw that your DF selling thread I think the price can buy the other same range nikon full frame camera with more advance focus system, Im not sure tho haha    sorry write so much haha hope you dont mind 

DF pretty much like a branded price with reduced function (like video, but we don't care although we mainly shoot images lol)

and people ignored the fact that DF is small size hehe... but they i think also dont care much about size when talk about DSLR XDD

also with that size and price i think you can get FF sony SLT easily right?
