  1. Looking at the front of your D3200, at

    the 7:30 position there is a little angled

    switch on the edge of the lens mount.

    This gets pushed in by the aperture tab

    on your lens. If this does not engage the

    error message does not disappear and

    the shutter will not activate. Your tab

    end might be a bit rounded and not

    getting the switch in far enough,

    causing intermittent problems.

  2. I have a D3200 and got caught the

    same way. Peter Hamm is correct. If

    auto ISO is on the manual controls will

    still appear to be changing ISO as you

    wish. The manually selected ISO will be

    displayed on the right hand side of your

    rear screen but "ISO-A" will flash in the

    middle. "ISO AUTO" will flash in the

    bottom of your viewfinder but there is

    no indication of what selection will be

    used as you fire the shutter.

  3. A modern 50mm would need to be

    stopped down to a smaller aperture to

    give useful sharpness. The optical

    formula is not designed for close-up.

    You would need a set-up with a

    mechanical aperture control of sorts.

    Even then I am convinced the iq will not

    be as good as can be achieved with a

    good macro.

     

    If you will not need a macro lens rather

    consider a film scanner instead

  4. The D3200 always shows the manually

    set ISO in the rear screen. This does not

    change to the slected ISO value the

    meter has at that moment when it is in

    auto ISO. Instead it has an "auto-ISO"

    flashing indicator nearby. Caught me

    out a couple of times. Basically for me it

    is easiest to begin with to have auto ISO

    running and only take it off for

    deliberate long exposures. As you pick

    up experience, then set it via the front fn

    button and the control wheel. (First

    selecting the fn button to ISO control

    via the menus of course)

  5. This example looks more like a lighting difference. Closer flowers

    are brighter than the rear. Warm lighting can also cause colour

    histogram distortion. A big problem when mixing tungsten lighting

    and flash. For a good test the lighting and target has to be more

    balanced.

  6. I have the s100 and it is nice but slow

    to focus. Hauled it out at a colleague's

    farewell and had to prefocus to get the

    right moments. Second shot was a grip

    and grin nightmare. Low light is best

    approached with a larger sensor as

    well. Good image for the money still if

    you can find one on special price sale.

  7. I am assuming above obvious

    considerations such as live view use,

    the lens being perpendicular to the

    centre of the photograph, the

    photograph properly flat and using a

    good macro lens. I tried and was still

    getting alignment issues. I decided to

    line up the scanner for my old pictures

    instead. And when the auto fade

    correction kicked in I was even happier

  8. Having astigmatism and different

    degrees of far sightedness in both eyes

    I quickly had to learn just how much the

    brain works to interpret what the eyes

    deliver. It makes for quite a

    performance when I am asked to check

    for level when someone is decorating. I

    use a spirit level for the simplest of jobs

    at home, and still measure both ways

    the first time I use the level.

  9. When in electronic format the size and

    dpi resolution are just add-on

    properties of the image. The vital

    properties in electronic format are your

    pixel counts. If you change the dpi

    rating the software assumes you wish

    to uprate or downrate the pixel numbers

    and uses the algorithms to interpolate

    or downsample your image. Why have

    this complication as part of your work

    flow at all? Just go in at the highest

    pixel numbers feasible and remain

    there for as long as necessary and only

    set the output size when printing. Dpi

    should just remain a calculated result

    of your image size, not part of your

    processing work flow to my

    understanding. If your original scan

    pixel numbers matches your final

    highest output required that would be

    the best outcome.

  10. I own the 70-300 but always end up

    using either +-90 or 300. Just got the

    85 f1.8, wonderful if I am careful to

    steady my hands. If I could fit a 180 f2.8

    or 300 f4 in my budget the zoom would

    be downgraded to using in rough

    conditions. The softness full open

    doesn't matter that much in a

    rainstorm.

  11. The biggest factor in sharpness is the

    shape and quality of the lens glass. And

    here is none.

    The way I imagine it is to visualise lines

    from the subject going through the

    pinhole. The same point back of the

    camera will be larger than the hole to

    begin with. The way to make the image

    sharper is to make the hole smaller.

    Unfortunately physics start to spoil the

    party at the edge of the hole. Here the

    wavyness of photons spread the light

    out. This diffraction effect is always

    there but becomes more important as

    the hole is made smaller. Pesky

    physics!

  12. Indoors is a relative term. Indoors can

    be anything from large windows facing

    the sun to so dark you struggle to read

    or photograph anything moving. If the

    light meter in your camera made that

    suggestion it would be about eight

    times darker if what you are pointing

    the camera at is something that

    averages to mid grey.

  13. I have the D3200 and 70-300vr and

    have been chasing the Zululand birdlife

    around for a few attempts. Nice

    combination when you get close.

    However going to extreme crops I do

    not think the D3200 would give that

    much better crops than the D7000. This

    lens at 300 mm gives less than 6mp

    perceived resolution on the D7000

    (according to DXO mark). The extra

    resolution will not give you significant

    more cropping potential because your

    combination is mostly lens limited to

    start with.

  14. The Nikon tele converters will not work

    with that lens. The dx lens reaches

    further back and might touch even the

    1.4 x converter.To get a longer effective

    lens you will need to haul out lots of

    cash. Next step in price for Nikon is a

    300mm f4 with a 1.4 tele converter.

    Roughly double again the price of your

    camera and lens together. Other brands

    of teleconverter might work but the

    view will be dim and auto focus slow or

    not functional. Optical quality also gets

    a knock. Finally just to clarify terms

    used, an extention tube is the term used

    for a focus extention tube. That gives

    you a closer focus for macro work only.

    A lens on an extention tube will not

    focus very far from the front of the lens.

  15. My favourite wide angle photograph I grabbed with my Galaxy S2.

    The point and shoot comes second. Only recently I got a dslr and

    the difference was clearer to me. Low light and I get pictures that

    were impossible before. I can now pick more interesting selections

    from most surroundings using the longer zoom. I believe the tool

    influences the images you look for and not only because of angle of view. For low angle close views the phone can occupy points of view the dslr cannot fit in. Except now my cat turns his head from the phone in case the LED shines in his eyes again.

  16. I have both the D3200 and the Canon

    Legria M56 camcorder. For baby and

    general video the camcorder beats the

    camera hands down. Ergonomics of the

    dslr with a mounted mic does not say

    one handed operation while the other is

    constantly dangling around baby and

    baby's "stuff". However you would need

    to go one model up from mine to get the

    more generic mic port. The real

    question I would still have before

    deciding is do you really need 1080

    resolution? That level depends on your

    delivery method. Blueray disk players or

    very expensive projectors are not that

    common in the corporate world yet as

    far as I know.

  17. A quick google will give you a useful link to a

    question and solution on a different

    forum. For now look up in your manual

    that using an unknown status flash on

    your Nikon can fry your circuitry. The

    trigger voltage on this unit is probably

    too high. You could use it on manual

    using a "hot shoe safe adaptor" device

    but say goodbye to your guarantee in

    that case.
