Harvestman Though I&#039;d love to, I&#039;ve little hope of identifying this guy further than this&hellip; there are more than 6,500 species of them identified and more than 10,000 suspected :p, but I brought home my extension tubes and was experimenting with them today. Not too shabby, if I say so myself. Lighting provided via an LED flashlight.<br />

Though they look a bit like a spider, these guys are actually not spiders- they are in the group arachnida, but are more closely related to scorpions. Another interesting tidbit - Unlike most arachnids they can actually eat solids. Spiders and scorpions have to render their food to liquids before eating and ticks simply suck blood.

  1. I love the experiment. In particular I like the deep depth of field, so much of it is sharp, which is very hard for this type of species. Well done! Posted 10 years ago
    1. I found I had to remove a pin from the extension tubes. For whatever reason the manufacturer had put in one that served to open the aperture wide open and hold it there…. understandable on something that controls your aperture from the camera, but these are just plain old manual extension tubes ( only cost $6.00! ), without any electronics... Fortunately it was a screw rather than a fixed pin so it could be taken out. Maybe that's for newer lenses without an aperture ring? With all of the tubes plus the x mount adapter on my 105 macro, the depth wide open is nearly nonexistent, so getting that pin out was vital.

      The whole setup is a bit long and heavy, and manual focus only, so I expect that I won't be doing much hand held shooting with it, but as long as my subject doesn't mind posing for a while, I can get really nice images. Funny thing is I bought them for work… it would have been a flat and definitely not live specimen. But it never materialized.. I think the experiment might have failed :o

      1. I don't understand this last part:

        "Funny thing is I bought them for work… it would have been a flat and definitely not live specimen. But it never materialized.. I think the experiment might have failed :o"

        Care to elaborate?

        1. lol.. yeah I guess I was vague. I bought the extension tubes for a work project - I was supposed to get a stained and fixed specimen from the lab demonstrating some type of special tissue in a rat esophagus, but the first one faded before they asked me to take the photos and I guess they were unable to repeat the experiment…. It was a very small piece of tissue and even smaller dots on it to visualize, too small for my straight up macro, which can do 2:1, but probably too big and thick for a microscope (which I don't have anyway). I was buying some stuff from photodix anyway and the extension tubes were so cheap it was a no brainer to get them. They've just been sitting in my drawer at work waiting, so I finally decided they'd be better off here at home where I can play with them. Posted 10 years ago, modified 10 years ago
          1. Cool, that explains it. What work do you do, if I may ask? Posted 10 years ago
