A house and a ?

I cant get the lights right with this 50mm lens. I tried diffrent f stops but it wont work for me. My tamron is loads more effecting making the lights get a nicer look. Whats also is a bit challanging is focusing with this lens. Althou i like it if i take other kinds of pictures and it does autofocus at night rather good to its alot harder to have it focusing then my tamron.

Someday i might get a more wider angle then 24mm i can get with my tamron but for now it will have to do. I cant make up my mind on one. I also want another lens for my birding but they cost aswell so i gotto decide on whether i wanna pursue the more nightly, landscape, street wize photo or go for my birds.
