Thread: Bokeh Comparison

    Default Re: Bokeh Comparison

    STF is similar with DC lens in Nikon right ?

    I think STF lens from Sony is :
    - Sony 135 mm f/2.8 [T4.5] STF (SAL-135F28)
    DC lens fron Nikon is :
    - Nikon 105 mm f/2D AF DC
    - Nikon 135 mm f/2D AF DC

    STF = Smooth Transition Focus
    DC = Defocus Control
    And I admit that Bokeh quality from both STF and DC lenses are very good. Those lenses like Creamy Machine.

    Some lens has biggest aperture until f/1.2, although other brands only f/1.4 with the same focal length, but having ˝ stop brighter at the widest opening doesn’t mean improving the Bokeh quality right ?

    The reason I create this thread in the Newbies Corner because I saw there were many questions about portrait lens and I try to open mind that shooting at big aperture doesn't mean that you can get high quality Bokeh.

    May seniors here recommend a "Bokeh King" lens which cost <= S$1000 ?


    Based on my 2 cents experience, I recommend Sigma 50mm F1.4 EX DG HSM

    Just buy a new lens, not 2nd, to minimize the risk of getting bad copy.

    For me, I would prefer to see bokeh comparison using out of focus highlights to see how smooth the bokeh is, coz some of the samples dun show that... A sample would be this snapshot I took, haha!



    Some of the best quality bokeh lens I have seen online(but not tried as I am too poor to afford them) would be the Minolta/Sony 135mm F2.8 STF and the Nikon 105mm/135mm F2D DC lens.

    I think they are still quite different, the DC lens seem to be closer to the soft focus type

    as the object will blur at 5.6, whereas STF have apodization element which only help to smoothen the background blur, and the object in focus will not show any blur.

    For me the best setup for best bokeh for portrait will be D700 w 85f1.4 135f.2DC or 70-200. They quite remarkable result though they arent cheap but a must have for portrait work. DX crop lose out in bokeh, but not as bad either.

    I read review of 135 f/2 DC, on this Setting :
    f/2 R=5.6 (rear blur)
    f/2 F=5.6 (front blur)

    Looks like that options effects image quality a lot, the main object becomes soft.

    Looks like STF (smooth transition focus) is a better technology than DC (defocus control) ?

    i cannot think of any single litmus test for appreciation of bokeh, with heck alot of personal taste, and of course individuals clamoring about their own products. but i do agree most of the lenses cited are great creamy lenses

    the 85f1.2 looks great to me http://www.flickr.com/photos/phohe/3144553140/

    even the nikon 85mm at f2 looks amazing http://www.flickr.com/photos/waiting...ie/3837344418/

    happy bokeying ..

    I am a bit surprise that although shooting at f2, it can create nice a bokeh (1.5 stop darker than f1.2)

    Yeah I am agree, with heck a lot of personal taste. Some people already be happy with f/1.8, some others are willing to spend thousand of dollars to buy f/1.2 or f/1.4 to achieve their personal satisfaction with the bokeh !

    DC lenses are not soft focus lenses... if set the DC to go pass (DC f number bigger than aperture f number) the aperture, it would become a soft focus lens (but only effective on f2 wide open, DC set to more than f2)...
