Guys, need some opinion. currently have Nikon 35 and 50 mm G lens. My pictures mainly consists of tight space, i.e. inside house, not bungalow

my take are mainly childrens and was looking at selling both these underutilized lens to get Nikon 20mm.

my question is what will I missed out from 35/50 if I acquired the 20mm or what would I gain with 20mm over 35/50mm other than wider.

my engine, D7000. your personal opinion much appreciated.

Thanks. I have the tokina 11-16. What I need is a light fix lens that I can carry around sometimes,where those big lens can stay home at a budget. I need to sell both 35/50 lens and maybe top up to get a used one. Wanna ask opinion as dun want to regret drop 2 fix lens for 20mm fix.
