Extension Tubes

When I don’t have my wife’s macro lens I have extension tubes. Are they as good? Nope! What they are is a cheap alternative, and they are just as satisfying. I would equate it to eating prime rib for three weeks, then being fed blade steak that was marinated. It was still good but I prefer the prime. I tried it with my 18mm-55mm lens canon, and the results were less than satisfactory. I switched to my 75-300mm and we are getting somewhere

Now I must admit I have only owned a Dlsr for  8 months and admittedly I have lots to learn. You only have to eat prime rib, rib eye, tenderloin, strip loin, once to realize blade steak although beefy is not quite as good.

My pictures are first with the 18-55mm  lens, then of the 75-300mm lens with the tubes beside it. Then my pictures of the same crab spider in evening primrose that I took today that can be found  here. The latter was taken with the 75 -300 mm lens and tubes.

  1. These are good shots – I have a few extension tubes but never used them much.
    Some come with glass but if they’re not high end optical glass they’re more of a
    negative than asset.
    The thing with macro is depth of field, I don’t believe there is a lens made even
    when stopped down to it’s max that offers the dof a person is seeking.
    That’s where focus stacking comes in which can be a little tedious and require some
    post editing time but the end results are worth it.
    People may think that focus stacking is limited to macro lenses but not so, find the
    minimum focus length of a non macro lens and start from there.
    Eight months and you’re on a roll.

    1. Thanks rezinate. You really know your stuff. I understand what your saying kind of. The 18- 55 lens with the tubes is to close to the subject blocking out my standard flash. We have a wish list of items we want soon. Flash is one of them .

      1. I’ve yet to see a built in flash on any camera that’s actually worth it as an
        all around tool, if your focus for an external flash is related to macro you
        might want to take a look at a ring flash – branded ones as to be expected
        are high priced but there’s some good third party ones available that will
        do the job and not break the bank.
        Some of them allow you to increase or decrease the amount of light they
        generate, which can be a plus.

  2. It takes a while to learn how to get the best out of the extension tubes. One thing to remember is that they have more of an effect the shorter the focal length of the lens is, so I’d stick with shorter tubes behind the short lens. But no matter which lens you use, it requires practice. I use an extension tube behind my 100 mm macro lens at times when I want to get really close to a subject. Forget the built-in flash of your camera, unless you carry something that you can bounce the light off from. My preference for macro lighting is a LED light which is on all the time so that I can see what the photo will look like, rather than guessing what a flash will produce.
