These were from 5 minutes after opening the box in a light rain...although I definately want to set up the tripod and use MF, I can see that these will be fun to have around...

    Nice shots.
    From my macro experience a tripod is OK for stuff that's fixed and not going to move away or move about in a breeze but for stuff that isn't fixed (insects, flowers etc) I've found a monopod is good as you can adjust it quickly to get the shot and rock back and forth to get the focus and take the shot immediately the focus is in. For that I use manual focus, set the focus to the right distance then rock the monopod back and forth until focus is in (using focus peaking).
    The monopod I use Manofrotto 334B has a squeeze hadle on the top so it can be adjusted quickly and easily and a ball head enables the camera to be orientated easily.

    Kiwi Paul- thanks for the info, I will give the monopod a try.

    Kmac - nice!!

    I have never done macro before, but I am becoming interested. I had not heard of Neewer brand before. What is the consensus among macro shooters of the pros and cons of various extension tubes? What should I seek and what should I avoid? Since most of my lenses are manual focus, Paul's tips are GREATLY appreciated!

    Thanks...To pick off the easier question (imo) the tubes are a helluva lot cheaper than buying a dedicated macro lens. In a post, I put up a few weeks ago- I was considering several Sony lens options from $300-$1000, although I still am looking, the set of tubes cost < $30 on amazon.com and will allow me to play in macro until I pick a lens (be it Sony or other maker)

    Nice shots!

    I think I would have stayed indoors to open the box if it was raining outside though.

    With nominal F2.8 lens:
    @1:1 you get about 100µm DOF in viewfinder (150µm DOF @f4 photo)
    @1:2 you get about 320µm DOF in viewfinder (785µm DOF @f6,3 photo)
    @1:4 you get about 1mm DOF in viewfinder (3,5mm DOF @f8 photo)

    With tripod + rails i get almost 100% hit rate, while using monopod or handheld i get about 10% hitrate at anything in range of 1:1-1:2, maybe 40% in 1:2-1:4, and i can comfortably shoot 1:4 and below handheld. Mind that im using flash to freeze movement, and tripod is just an aid for focusing. So my monopod ended up in RIP closet, try it out before you buy it.

    JMM - this is the kind of information I need, thanks! I can get 1:2 with my lens without extension tubes. So I think the direction I should take is this:
    Start using 1:2 to learn the trade, so to speak. Do not get tubes until I understand what I could do with them and how they would impact my photography. This makes sense to me.

    I thought DOF also depended on focal length and image circle size? I don't know for certain, but I do know for me anyway DOF is by far the most difficult thing with macro.

I planned on trying it over the next day or so, but I figured I would throw it out there ahead of time... here a couple of shots from today... I like the idea of the slider- seems like a good idea...

    No.
    @chalkdust@chalkdust with 26mm extension tubes and 65mm F2.0 you should get an equivalent to 65mm 1:1 F2.8 macro lens and viewfinder brightness gonna be close to F4. Working distance can be a bit limiting.

    Myself and most photographers i know, feel that tubes are only temporary solution until you get proper macro lens. They are really cumbersome to get required magnification. My personal lens choice for fieldwork is Minolta100mm 2.8 1:1 via LA-EA4 and Mp-E65 1:1-5:1 via commlite adapter.

    John- I get these measurements in a DSLR, but given a mirror-less ability to provide WYSIWYG with "settings effects on" wouldn't the viewfinder show the actual DOF @ a given aperture?

    Nope, you get wide open live-view, camera just compensate brightness for your F-stop. You would need to get custom buton for aperture preview and keep it pressed while focusing (a6000/Nex3, maybe there is different option in A7XX). That's obviously not a case with manual aperture lenses, where you get full DOF in viewfinder.
    Still, imagine if you would get it, your whole body cant move more than 3,5mm to keep critical plane focus @1:4 F8! At 1:1 with 100um dof getting focus where you want is pure torture.

    Both May A6000 and a7R do not give me wide open live view with Live View Display = "settings affect on". With Sony AF lenses the camera stops down to the aperture setting during focus. When settings effect off, the camera focuses wide open. This is not the case with adapted lenses. However, this is the case with most E-mount lenses. In fact there are 100s of threads dedicated to this behavior not being optional on A7RII, wich causes camera to not take advantage of bright lens set to small aperture.

    Hmm, that might be the case! As Sony have no good macro lenses in E-mount systems, im using only adapted lenses.

    ^^^Thanks for sharing that Gary. I need to explore more of my camera's settings.

    Did you notice that model didn't blink once during that whole video?

    Fly just come by for testing, so if you get full DOF in viewfinder, thats what you gonna work with:
    -F11 (EA22) 1:1 ; in diffraction territory already so 1:1 is in "empty magnification" field. Focus plane is 1mm deep. Nailed the focus here as focus plane starts right after antennae and ends right where head does. Took 10 shots to get this one.
    muchafront1.
    -F16 (EA32) 1:1 waaay into diffraction territory, 2,25mm DOF. Despite taking 10 shots, couldnt get a focus on eyelenses.
    muchabok.
    -1024 Crop for detail:
    1024crop.
    As you can see, focus starts on wing hairs on the left, but ends just where head is. Images were taken with flash, it's not motion blur, it's diffraction softening.

    Normally i wouldnt go below F4-5,6 on 1:1 with A6000, as not only bokeh gets ugly, but also diffraction ruin images. Sadly, focus-stacking is the only way to go.
    But lets say you want to make web-sized shots and dont need the resolution, so you shoot with f11-f22 and you're getting real DOF in viewfinder. It doesnt really help! On the contrary cause as i just checked with SEL50 on macro tubes, image get SUPER-HIPER-OMEGA noisy and i cant get the focus plane at all (lens is working on EA22-40).

    Not a fan of the FE 90mm macro?
