Plastic lens

I have been meaning to get a Diana F+ camera and instead I got this Diana F+ 20mm fisheye lens with the Canon EOS converter. I don't know why I'm so hesitant when it comes to film cameras. I have a Canon film SLR which is fun and exciting to use once in awhile, but there's something about the Diana F+ camera that keeps on drawing me in. I swear on this website that I am getting one as soon as I land a job!
