Extension Rings
Doing good macro work on the cheap.
Incredible cheap macro system. That is how we can describe macro rings.
On ebay their price can be around 8 to 10 dollars or euros and in a secondhand photoshop
anywhere between 5 to 15 dollars or euros. This wil get you 3 to 4 rings varying in size
from 5, 6, 8, 10, 14, 25, 27 millimeter and there are more variations. They work on a
very simple principle. They change the focallength of the lens. Another variation is the
Reversal lens, it simply puts on the lens backwards on the camera. Though I love the
general idea, the Reversal ring I don't like. The reversal ring exposes the back element
of the lens and it is hard to protect it. You can get good results with the Reversal ring.
But I would not recommend it. It isn't as versatile als the Extension rings. And there is
a real danger that you can damage the lens rear element. You can however protect the
rear element of the lens using an extension ring.
Both these shots were made with extension rings. Good quality.
Then there is one left, the close up filter. A lens that can be put on front of
the normal lens so you can make macros. These are usually intended for cameras with
a fixed lens and I can't say that I have seen good quality among them.
But I don't have much experience with them.
