New lens

I saw these lenses online and they were so cheap that I decided to buy a 50mm F1.4 lens. Since I have Sony Nex a-6000, I needed a C-mount converter. The price for the converter was about $7, but there was also a 35mm F1.7 lens with converter and 2 macro rings for sale for about $24. So I decided to buy that one as well.
I need to be able to focus manually, which is a challenge, but I'm learning :-).
