Hello everyone. Today I want to talk about Micro Photography which when done properly can open a whole new world of photographic possibilities for you. First, let me tell you which lens I use. I have an EF 50mm f.2.5 Canon lens. This is by no means a top of the line lens, but this one that I own, have great glass which in term translates to beautiful sharp images.
Last week during the studio light class give my students a little demonstration of how to use it with and without extension tubes. I am including a couple photos and more information about the lens and the extension tubes in case you want to purchase your own.
These photos of the inside of a red bell pepper were created, first using the minimum focusing distance of the lens. I normally don’t bother to focus; I just extend the focusing to the minimum focusing distance and then move in close until I see the object sharp. When I see it sharp, I take the picture. The second image is the same pepper but this time I placed a set of three extension tubes between the lens and the camera body. By doing that I can decrease the minimum focusing distance by several inches, in that picture you can see that I was so close that I capture just a few seeds and the vein in the background out of focus. Again, this was accomplished by using extension tubes which increases the distance between the camera and the lens allowing you to get about 3/4 of an inch close to the subject. Since extension tubes do not have any glass in it, they do not affect the quality of the final image; I use Vivitar extension tubes for my camera since they are about $300.00 less than the Canon extension tubes. The following is a link to the Canon lens that I use.
This is a link to the Vivitar extension tubes.
Just for comparison look at this Canon extension tube, the price is for ONE, not a set of three like the Vivitar. Again, these tubes have no glass! So if you can afford it and want just Canon stuff or Nikon or whatever you use, buy them. I use items that work with my equipment and do not hinder the resolution of the final image.
