During last years challenge I believe Julie(?) posted a little tut on reversing a 50mm lens to produce an extreme macro shot of some flowers. At that time I said I needed to try it out. Well, months later, after approximately 40 attempts here is my best from the session. I’m pretty happy with it but I do have to say it was an exercise in patience. The hardest part was positioning and keeping the lens steady for the split second of pressing the shutter. The dof is so small, that any, and I mean any, movement will result in a blurry picture.
So, if you have such a lens and have the patience, all you do is take off the lens, flip it over and press it against the body of your camera. Compose the shot and fire away. In this scenario just keep clicking away and eventually you’ll end up with one keeper. Give it a try. I’d like to see your efforts!
