maps for farway places
This was an experiment with a vintage Canon FD 17mm lens connected to my DSLR. The adaptor moves the focal plane and reduces the ability to focus on infinity. With most FD lenses on digital this is fine and just means you get a close up or macro lens.
But when you do this with a lens that is as wide as 17mm then you have no focal plane at all! This leaf is actually pressed against the front element of the lens with the lens focussed on infinity! So this is the best focus you can get with the object actually touching the lens! Never tried this before.
