    f8, indoor without tripod? :O Handshake la. Try using a tripod. If you must handhold, try a larger aperture (in your case should be f4.5) and pump up the ISO.

    You can handhold, provided there is enough light. Low light (indoor) will need longer shutter speeds and handholding is a challenge (especially at f8)

    Either use flash or try larger apertures and higher ISO

    Yes, using zoom lens, I think beyond 3x hand shake is almost inevitably present unless you are very good at it. Me I'd prefer to stick to a tripod, or at least solid base so there won't be handshake.

    Indoor pictures without tripod;

    1) Use flash if it's suitable
    2) Use larger aperture
    3) Use higher ISO, but not to the extent of blurring out all the details because of noise

    for a start, switch to speed priority instead. for the beginning, try use shutter speed at 1/focal length, meaning if you zoom to 200mm, try use 1/200sec shutter speed. once you're ok with such settings, you can try shooting at slower shutter speed, it's about training yourself and getting used to shooting with long zoom.

    AF can lock or not.
    i wonder if you are getting sufficient focusing distance from your subject and your lens.

    Reading up on photography basics will help; ie. stuff like what aperture does, what shutter speed does, what higher ISO does.

    There is no real rule to follow, so long as your exposure is correct and your detail that you want to capture is there.

    If outdoor if you want to shoot something in the shade using the general rules won't help. Generally when there is a lot of sunlight, depending on the amount of detail and DOF you want to capture, you can play around with aperture and shutter speed.

    In brief;

    Aperture = how big the hole in your camera is (ok this sounds weird). Bigger hole = less depth of field, ie. other than the area of focus, the rest of the details will gradually be lost based on distance from area of focus. Hope I got everything here correct technically. Smaller hole = more depth of field. However, aperture number is in f-stops. Bigger f-stop = smaller hole. Smaller f-stop = bigger hole. The hole will let in more light at one time if it is bigger.

    Shutter speed = how long the hole in your camera opens. Longer = more light. Shorter = less light.

    How much light is captured based on your aperture and shutter speed settings would determine how good the exposure is. In general, almost every situation has varying good aperture and shutter speed set settings. But you can play with it. Aperture up, can lower shutter. Vice versa also works. In some cases people like to overexpose and underexpose. Generally it is good to have good exposure because all the details you want will be there. And underexposure is usually better than overexposure, since detail is definitely lost in overexposures.

    Ok that's all I can think of. Go read!

    in short, please read your manual and try out yourself, you might be better off trying out with your kit lens for now..

    Yeps. Basically what happens in TV (or shutter speed priority).. Is that your camera selects the best aperture setting for your shutter speed. In this case, even the biggest hole (or aperture) won't save your exposure so it comes out black; insufficient light in short.

    Yes, if aperture is constant, a faster shutter speed will capture last light, and render a darker picture.. In some extreme cases.. Black picture.

    hmm i see...

    so can i assume that at low light condition it is best to use high iso and Av(small f-stop=bigger hole)?

    then use Tv when want to capture fast movement picture and with alot of light?
