I found out about this little beast just a few days ago. I came upon Flickr's Olympus XA group and learned that you could get similar, if not better, results than the Lomo for much lower price. It too gives rich, saturated colours, and vignetting just like Lomo does, with sharp focus!
Within minutes I found myself looking through ebay and kijiji to look for one. Fortunately, I was able to meet with a nice gentleman in my area who offered me this combo for $60!
So. Meet my friend, Olympus XA. Can't wait to see the result :)
