Which prime lens should I buy for my Sony Alpha a6000 because I am totally lost with all these different numbers and brands? I just got this camera used from a friend because I wanted to start taking better photos of my family and maybe some of the stuff I cook but I'm realizing the lens it came with isn't giving me that really nice blurry background that I see everyone else getting. Someone told me I need a prime lens but I dont even really know what that means other than it doesn't zoom? Which sounds kind of annoying but if it makes the pictures look better then I'm down to try it.

I've been looking at stuff on Amazon and B&H and there are so many options it's making my head spin. Like there is a 35mm and a 50mm and then some say f1.8 and others say f4 and I have no clue if a bigger number is better or worse for what I want to do. I live in a pretty small apartment in Seattle so I'm usually pretty close to whatever I'm shooting and I'm worried if I get the wrong one I won't be able to fit everyone in the picture without hitting the wall behind me.

My budget is pretty tight like maybe $250 or $300 max because I already spent a lot on the camera body itself. I'm hoping to get something before my sisters wedding next month so I can practice a bit. Here is what I think I need:

• something that works good when it's kind of dark inside
• making the background look blurry for portraits
• not too heavy because I want to carry it around at the park
• something easy for a total beginner who doesnt know settings yet

I'm sorry if these are really dumb questions I just feel overwhelmed by all the technical talk online and just want to know what the standard first lens should be for someone like me who just wants pretty pictures of their kids and dog...
