Not having lots of money for camera gear, I learned to do a lot of things inexpensively. The 50mm f1.8 is what I've used for probably 90% of my macro photos. You can get a peek at my results here: https://www.flickr.com/photos/euloth...57627342063753

I generally just flip the lens around backwards at around f11, f16 and hand hold the lens against the body of the camera, however, you can purchase reversing rings on eBay for around $4 so you can properly mount it backwards.
