>>3779194We're on the same page my dude.
Nikon adapters without using a lathe exist, but if you want infinity focus then you need an optical element that degrades the image (pic related).
If you're into DSLRs and meme glass, Canon and Pentax are the best.
Also the importance of the articulated screen cannot be understated. I lost it going from crop to FF, it was great.
When people ask for camera recs under 500 bucks my go-to options are 60D, 70D, K-S2 and K-70. Pentax is best if video isn't a concern because of SR and that magic teleconverter that adds AF to manual lenses.
