After a lot of trial and error, I finally figured out how to modify a "high quailty" all plastic Holga "toy camera" lens to work on my Canon 300D. I had just enough light after the glue dried to snap a quick pic at 1600 ISO. Here it is If you do not know what a Holga is, they are all plastic cameras made in China. They take 120 medium format film and are very popualr in the art B&W side of things. I have been wanting to do this for a while, and I found a few obscure webpages that hinted it could be done. And it can. Here is what the lens looks like If anyone is interested I can post a how to in the how to boards so you can do it yourself.
