As you may know from reading some of my blog entries I like to mess around with unsual lens combinations. This morning I attached the Toy lens onto the Olympus EP2 and then screwed in a +10 macro lens.
This macro lens is part of an old fisheye macro converter. It gives good sharpness in centre but falls off at the edges. Combine that with the crazy Toy lens and you have ultra fall off at the edges.
And here's what happens. This is of a chestnut leaf. The focus distance is about 4cm from the subject.
