The 50mm f/1.8 lens I ordered on ebay is in. It's an older one (from the 80's), and although it has a bit of dust, I'm really happy with how it works. It's heavy (made entirely of metal), and the focus and aperature rings turn nicely.
I was in Seattle doing some sailing for the weekend. Here are a few pictures I took with the lens. Not much to say about them. Didn't really make many adjustments. Judging the exposure (given that my camera body has no clue what aperature the lens is set to) isn't as difficult as I thought it would be. I usually get it on the second or third guess. Focusing in some circumstances can be tricky, but this is something I imagine will come with practice.
Here's a picture of a lamp shade, one of the first pictures I took with my new lens.
And here's a picture of my mom having a snack on deck between races.
More to come.
