Review on 📷 K&F Concept PK K Mount Lens to Sony NEX E-Mount Adapter: Compatible with Sony NEX-3/3C/3N/5/5C/5N/5R/5T/6/7/F3/VG10/VG20 by Travis Petty

This adapter seems to be quite well made but using the K-mount version of the adapter on the Sony A7r Infinity Focus seems very far off. I have provided 2 photos, both taken at f/2.8, the sharper one has been slightly shifted from infinity to get in focus. This is on a 14mm Rokinon lens and focusing starts at around 7ft or so, images are cropped 1:1 with subjects over 50ft away. To be honest I'm not sure how much this will affect things, I'm mostly worried about astro shooting, the same lens on my K-50 set to infinity was the place where shooting stars became easier. Update: The price of this adapter as of 1/1/2020 is more than double the price I paid just 3 years ago.
