Holga Lens on my Olympus E-PL1

One thing I like about micro 4/3 digital cameras such as my old Olympus E-PL1 is it's ability to accept many different manual focus lenses designed for other 35mm cameras. Recently, after reading about it in another blog, I bought a Holga 25mm lens designed specifically for micro 4/3 cameras.
I have a couple of Holga 120N film cameras and I like the soft, vignetted images they produce but lately I haven't had a chance to develop my own black and white film so I thought I'll give this Holga lens a try. It is a cheap plastic lens available from eBay and has only one f-stop, f8. Focusing is done by manually using the distance symbols on the lens barrel as guide but with the micro 4/3 camera you have more precise exposure and focusing control than the Holga film camera. The EVF on my Olympus also helps in framing and focusing more precisely. The lens did produced a Holga effect but the film camera still has some subtle nuances that I like better, maybe I'm missing the light leaks.
