    What exactly is diffrent than the extra 1/2 stop and a lot of money?

    Different optical configuration renders bokeh completely differently. Probably some weird optical properties of the glass in the 1.4 too.

    I think it is 2/3 of a stop faster actually, not half.

    From comparisons I've seen, the bokeh is better for the 1.4

    Some people care, some don't. You have to make up your own mind obviously. The 1.4 is also significantly bigger and heavier than 1.8
     
  4. It is one stop faster.

    Sorry, but this is not correct.

    Going from 1.4 to 2.0 is one stop

    obviously, going from 1.4 to 1.8 is less than a stop.

    Cheers.
     
  6. How do you figure, Vinh? f/1.4 is one stop faster than f/2.

    The trick with the 85/1.4 is not that it's so much faster than the 85/1.4. It just has a nicer bokeh, a narrower transitional area, and a different "feel" to its renderings. Some people don't value those differences, and some don't even see them. They're the lucky ones, because they don't need to break the budget with a $1,000 prime.

  10. In contrasty light the f1.4 can exhibit color fringing. See the pic on this page-

    Yup, it's 2/3 of a stop.

    (1.8 / 1.4) ^ 2 = 1.653 ~ 1.66 = 2/3 stop

    I am not a pro

    by any streach of imagination. :smile:

    I do not make any money selling photographs. I just shoot for fun. Moreover, like you I already own the 105 dc and 85 1.8. I was just curious, just how much different the 1.4 will be...people who own it really rave about it.

    85/1.4 is the king for portrait. It will make all your lenses obsolete! Not only does it have better bokeh and faster speed, it has that SPECIAL FEEL that other lenses do not come close. :)
     
  14. Maybe rent them both and do your own comparison...

    I wouldn't trade my 85/1.4 for anything...all of my "keeper" shots have been taken with either this lens or the 70-200...

    John, nice shots and beautiful models. I have to agree with you. No matter how much lenses I tried and used, at the end, most keepers are from 85/1.4.
