I suggest that extension tubes, with automatic aperture, can be made from cheap teleconverters. The 'four element' teleconverter is typically about 25mm deep, and the 'seven element' teleconverter is typically about 35-40mm deep.
Buy one at a camera show or eBay, often they are less than $10, I've even gotten some for $1 in the 'bargain box' before. Condition of the glass doesn't matter for this use, so you can sometimes get them -real- cheaply. Typically these teleconverters have an auto aperture mechanism in them... just take out the glass elements while being careful to not damage teh aperture mechanical bits, then you have an open tube that preserves the auto aperture operation. |
