Pipe Extension Tube

Thanks to my wifes new camera I was able to take these pictures of my Pipe Extension Tube set-up.


The "Pipe" in this set-up is a 100mm length of ABS plumbing pipe with a 30 year old 50mm 1.8 lens on the end of it.


The part that I have not mentioned in previous posts is about this flash arrangement. Using my SB600 flash..I rigged it up to a downspout from an eavestrough....OK, stop laughing....


The white ends are inserts for downspouts designed to keep leaves from going down the spout...these are plastic pieces and are easy to cut and shape to accept the profile of the flash and the lens.


I was fortunate that this "curve" in the downspout was perfect for the length of tube and lens combination!


Focus is achieved by moving the camera closer or farther away. For more minute focal lengths I use the lens to move the focus point. Not an exact science but I have been able to get the hang of it.


The depth of field from this lens is extremely small.

I have taken as many as 22 images of one spider with this set-up without the spider moving a muscle. Stacking all these images into one image through Photoshop results in a really really small spider really really sharp.


UPDATE! AS OF MAY 2011 I BOUGHT A 50mm 1.8 NEW NIKON LENS. I find that this new lens is much sharper then the old one (of course). It cost me under $150 which is cheap for an excellent lens.
