If you use a 2x teleconverter, you get 2x magnification at the minimum focus distance. With my digital camera sensor, the capture area is about 11mm on the long side with a 2x teleconverter – pretty close. Since you still have working distance, you have more freedom to try different angles without hitting the subject. If you use a reversed lens you’ll have more magnification, but you’ll be on top of the subject. This image uses a 2x teleconverter and 25mm of extension. It’s also another complementary color image.
