    Default Newbie question on 50mm 1.4 lens on a FF body

    Hi all,

    Currently, I have a Canon FF camera and own a 85mm 1.8 lens.
    The 85mm lens allows a really nice boke at a reasonable distance for portrait shots.
    What would a 50mm 1.4 lens look like as compared to the current 85mm lens I have currently.
    I was thinking of purchasing the 50mm 1.4 lens.
    Can some kind soul enlighten me?

    Appreciate the advise.

    Cheers,

    Anthony

    To me, 50mm is my photojournalistic lens, while 85mm is my candids/portraiture lens. Then again, people can argue to say that 35mm is their preferred choice for photojournalistic shots.

    50mm offers a view which neither 85mm or 35mm can. 85 can be too tight and creamy at larger apertures, losing alot of background and foreground detail, whilst 35 can give a slightly distorted look when going too close.

    When it comes to the nifty 50, you either hate it or love it. I love it.

    depends how you use it.

    If you know how the 50mm works, the 50mm f/1.8 is one heck of a great deal.

    At f/1.4 or larger, the DoF is going to be razor thin so dont mistake OOF for blur.
    You wont see me much less remember me but i am the guy who makes you look good.

    Hi Reportage,

    Just to clarify, when you mean the DoF is going to be "razor thin" for a 50mm 1.4 lens, does it mean that that it will have larger bokeh effect than a 85mm 1.8 at a close up distance?
    Appreciate if you can explain a little more..

    Cheers,

    Anthony

    Razor thin DOF probably means that you get the right eye sharp but due to the 1.4 the left eye might not be sharp ( Possible to get both eye sharp but not as easy ). At 1.8 easier to get both eye sharp. All these also depends on how close you are to subject

    Depends on how you use it, f1.4 on 50 mm isn't really that thin of a DoF imho, especially at further focusing distances.

    Since the 50 f1.4 EF focuses as close as 0.45 m vs 0.95 m on the 85 f1.8 EF, you could get a stronger background oof effect, but pls refer to the DOF charts as i'm not too sure either.

    However, the 85 @ f1.8 will have a stronger blur effect at f1.8 shooting the same subject framing as the 50 @ f1.4. This is due to the longer focal length.

    Bokeh is also much creamier on the 85 f1.8 EF.

    Hi,

    Just curious what would be the difference in the photo taken from a 50mm 1.8 lens Vs a 85mm 1.8 lens on a full Frame camera?
    Would be great if someone can advise.

    Cheers,

    Anthony

    here's an example, canon 50mm f1.4 + 5DMKII.





    note: image may not appear as sharp... it was later found that using Iphoto + borderfx... it somehow reduces my picture quality

    pardon the borders i set. now i dun use borders anymore.
