    Ok, see this example... bokeh enuff?



    your subject has to be much closer to your camera than the BG.

    Here's another example :



    subject is almost at minimum focusing distance, and the cat at the back was about 1.5m away...

    Unsharp picture maybe due to motion or handshake, not necessarily only OOF.

    It looks like the focus point seems to be wrong, seems to be focussed more on the foreground then the car. But in order to get a shallower Depth of Field, you need to get closer to the car or use a telephoto lens. 50mm F1.8 focal length does not create shallow enough depth of field at that kind of distance.

    Refering to the first picture in the post, hehe!

    f/2.8 1/800", 50mm. Needed min shutter speed = 1/75". The pic is not focus properly instead of camera shake. Also, trust your camera, use P or A mode as starter, and leave M mode until you know what you're doing.

    i'm not a mathematical person
    i feel the car is too big + you are standing too far from the car + background too near to car

    if whole car clear, bokeh will be little
    if partial car clear, bokeh gao gao
    otherwise, use flash to cheat

    yes... looks much better.
    Once again because the entire car is in view, that means you were quite far away with the 50/1.8, hence the background is just slightly blur. Can't help it. That's about as good as it gets.
    I'm not sure if using 35/1.8 and then going closer to get the same framing will help.
    Anyone??
    Exploring! :)

    For the same subject size (on frame), the DOF is almost the same for the same aperture regardless of the FL of the lens used. The bokeh may appear different thou.

    If the subject is already moving, make sure you DON'T move as well.... the focus will go off..

    The car is a better example. Just keep trying and you'll figure it out..
