I've bought this lens about 2 years ago, and i've taken thousands of pictures with it. This lens is so cheap, if you're just starting taking pictures and you want to check if primes are for you, you just have to buy this lens.
I have enjoyed this lens a lot untill it just fell apart a couple of days ago.
It's a plastic lens so you know that you can't use this lens forever so I've decided not to buy another one but instead go for the sigma 50mm 1.4.
So if you want a good, cheap prime, check it out, but if you want something durable and well built, DON'T buy this lens.
