    So latly i've been reeding more and more about this on 40-150 Pro lens, today even Photozone give a review abou lens and said:
    "The Olympus M.Zuiko ED 40-150mm f/2.8 PRO is, mostly, a highly desirable lens – except for one bug. On the positive side, it is very good if not excellent in the primary image quality metrics. It is very sharp across the focal length range including some greatness in the middle portion. Vignetting and distortions are very low. One the downside, the quality of the bokeh (out-of-focus blur) can be disappointing – not in all scenes but busy backgrounds are clearly not the lens’ best friends."

    I bouht lens few days ago and i didnt shoot in many light situation but even few of todays from zoo - Unfortunately, I can say that they are right and it is a shame that the olens of this class have such problems :(
    Lens is near perfect in 5m redius but after that all light ( backlight, contra-light ) makes problem - even worse is that I have 50-200 and on 50-200 I didnt have that much or maybe not at all problem like this and i did about 15-20.000 shots with 50-200 :(

    also - lens is super sharp on close object let say up to 10m, but on the far 15-30 and further ehre is no more sharpnes while on 50-200 you can zoom on 100% on 10km away and stil have very shrap picture...


    so i know there is many owner here on forum and I would like to know your experiences with 40-150 PRO

    At 10km you'll have problems with atmospheric effects no matter the lens... not sure how you'd compare unless it was side by side on the day.

    I'm the kind of person that cares more about the responsiveness and sharpness of a lens and less on the bokeh, as I can change that in post if I so choose.

    Probably not the answer you wanted to hear, and one would hope that the bokeh would be somewhat better on a $1500 lens, but bokeh is a subjective thing anyway. People might scoff at the bokeh characteristics of the Petzval lens, but that lens just got reintroduced not too long ago through a Kickstarter campaign.

    yes but bokeh on the last picture is like on 300 or 500mm miror lens - "Doughnut bokeh"

    The 50-200 is like this too FWIW.

    These are both with the 40-150mm + MC-14 at 210mm:
    E3174330-Lesser Goldfinch-male-1300.

    E3084113-Western_scrub_jay (California)-1.

    The 'messy' bokeh in the first pic is rare for me, even with the TC.

    Note both are 100% crops; f4 @210mm.

    Yikes, that is pretty awful background blurring there. The whole point of shallow DOF is to get your eye away from the background, not draw yourself to it in an unpleasing manner. :(

    I've heard that TCs tend to make it worse.

    Again, it has been rare in my pictures.

    i said that you can get good bokeh, but only if you are close ( like on your second picture ) or if there is no buisy background behind subject you focus

    What aperture? Those look like busy backgrounds and are relatively in focus, not out of focus.

    for comparison here is the 50-200 in a less than complementary image:

    full.

    And the 150f2

    full.

    full.

    I have to go do some test shots with the 150f2, the 50-200 and the 35-100. Most zooms do less well with busy OOF areas. Some A-B testing should be interesting.

    atm until sunday i have 2 em1 and 40-150 pro and 50-200 so i will do side by side test, but this shouldnt happend with 1500$ PRO lens and this made me very disappointed :(

    Now i wont sell my 50-200 - she never let me down i iq and she is 5 times cheaper atm in my region.

    40-150 is gem but this is not small problem :(

    The 40-150 f2.8 is sharp, fast and contrasty. I'm very happy with mine and have nothing to complain about with image or background quality. I'm keeping it!

    I have and love my 50-200 SWD and because it performs so well have not gotten the 40-150 Pro. I am really curious about a side by side comparison between the two. Look forward to seeing your results.

    I have seen it in some of my shots, but not many. I could swear that I saw it in some of the shots from the 50-200 that I tried out over a weekend. I've seen similar behavior with a full frame camera and 85 1.4 @ 1.4. I figure it's my job to notice and shoot around the issue.

    Harsh and ugly backgrounds make harsh and ugly bokeh!

    Distance was 35-50' in both pics. However, the background was further away in the second.

    iirc, both are 100% crops.
