    Default Extension Tube Test shots

    Hi all,

    Just to share with you all some of the macro shots taken with the various extension tubes setup. All these were taken with the 85mm f1.8 at Av mode set at f1.8, handheld.

    No need to comment why it was not taken at f11 above for macro cos din bother to use tripod or flash. Just to share the magnification you can expect from these various setups and the DOF at Ap of f1.8

    85mm with no tubes


    With the 20mm tube


    With the 36mm tube

    Getting harder to handhold when I started stacking more Tubes

    20mm + 36mm


    Ultimate: 12mm + 20mm + 36mm

    hmmm how about AF?
    do you think its impt for macro work?

    AF should still work. Heck, my AFS works with 3 stacked Kenko tubes too.

    AF/AFS however does not work well under such magnifications.
    My experience is the longer you stack the extension tubes, the more hunting it gets.
    But when shooting macro most ppl will work at manual settings

    Definitely important for macro even if you have macro lens. Just stack them up and shoot!

    Hi yehosaphat, would you please advise on the use of the extension tube:

    1. How do you get micro shot with extension tube? Is it like close up filter which allows your lens to have shorter working distance, so that the lens can move nearer to the object?

    2. If Qn 1 is true, then does it mean that I would get much out of an extension tube when I use it with a micro lens (say Nikon 105 micro VR), as the working distance of this lens is already very short and the subject almost touches the front element....

    I ask because I am thinking if the extension tube help to get mico shot larger than the 1:1 ratio.

    Thanks!

    1. Close up filter is like a lens, fix in front of any lens... with diopter of +1,+2,+4 etc... extension tube is fixed between the camera body and lens. works in the same manner, makes you get closer to the subject for focusing. but Close up filter is a piece of glass, no matter how great it may be, it will degrade quality to a certain degree, esp those cheap close up filters, will introduce flare, glare, and degrade in color and sharpness.

    2. yes, you can go beyond that. your 105 micro is 1:1, if you add extension tube it would be going beyond that. (infact, with a 1.5 crop, its already beyond)

    The more extension tube you stack, the more light lost there will be, so your aperture for 105micro wide is f2.8 (iirc), then if you stack extension tube, may drop to f3.5 beyond wide. but thats nothing... since in macro, we may even need f22 for some insect shots.

    For G lenses (no aperture ring), get an AF extension tube set so you can control the lens aperture from camera body .

    Otherwise, just get any MF extension tube. At very high magnification rates, you'll almost always use MF. Very rare you'll AF.

    Can i ask if i'm using a macro lens already do i really need tubes?
    have more tube will get better mag but lose light per stacked tube right?

    Yes you can still stack your macro lens on tube for higher magnification.

    For qn 2, you have answered yourself.

    Wah sorry for the slow reply. Was super busy lately and looks like the questions have been answered Well ext tubes are really well worth the investments esp if you like macro. It cheaper than the lens itself and yet easy to carry around esp for travels

    I understand the MP65 is 1 difficult to use lens.
    Help me confirm my thoughts in comparison to the MP65

    So stacking Tubes will be easier to use and even better when combined with 100mm 2.8 macro from canon because this lens got very large focusing range right?

    Tubes have greater magnification effect if you use a shorter lens. Of course, the working distance is shorter also.

    Have not used the MP65 before so cant really comment. But yes, the longer the focal length the more working distance you have

    Extension tube is very useful for macro because the OP will not have any significant drop.

    But avoid stacking too much as it will cause diffraction as shown in the last two photo.

    Yes, stacking of tubes will 100mm macro is easiler to use.

    Even you stack 12+20+36mm together with 100mm, you still unable to reach 2x mag rate.

    MPE65 is talking about 5x mag rate. The act like a reverse lens mount an a bellow, the viewfinder is dark and at high mag rate and very shallow DOF, getting your subject in view is a challage.
