    if i understood your statement, you are saying 2 stops down from wide open would be the best, but I can't really understand your last statement. For some lenses it does looks to be 2 stops best. This lens though looks to be best sharpness (center and corner) around F4, which is about 3 stops, just based on what I had shot and compared.

    Been getting some request to do a side by side comparison of Olympus 25mm F1.2 Pro and mZD 25mm F1.8. Here's a shot of the bokeh with a tricky background, left is Pro lens, right is F1.8 lens. Which bokeh do you like?

    Some Comparisons with 25mm F1.2 Pro vs F1.8. All shots taken with Pen F, same settings of ISO80, Jpeg, no sharpening or processing. IBIS off, and on support and 2sec delay timer. 2:1 magnification on Lightroom.

    Original scene.


    Center Crop. Wide Open F1.2 on the left, F1.8 on the right



    Corner Left Crop. Wide Open Shots F1.2 on the left, F1.8 on the right


    The centre crop, honestly, I can't see much of a difference, that actually shows how good the 25/1.8 stack up to it's Pro counterpart lens. The corner though is where separates the 2, 25mm Pro really shines here.

    Center Crop F2. 25mm F1.2 Pro Left, 25mm F1.8 right



    Corner Left Crop F2. 25mm F1.2 Pro Left, 25mm F1.8 right



    Center Crop F2.8. 25mm F1.2 Pro Left, 25mm F1.8 right



    Corner Left Crop F2.8. 25mm F1.2 Pro Left, 25mm F1.8 right


    Stopping down a little more at F2, F2.8, can see that the centre sharpness of 25mm F1.2 Pro is better than 25mm F1.8, not a whole lot though, but yet again, the corners 25mm Pro just leave the latter in the dust.

    Center Crop F8. 25mm F1.2 Pro Left, 25mm F1.8 right



    Corner Left Crop F8. 25mm F1.2 Pro Left, 25mm F1.8 right



    Center Crop F11. 25mm F1.2 Pro Left, 25mm F1.8 right



    Corner Left Crop F11. 25mm F1.2 Pro Left, 25mm F1.8 right


    With diffraction setting in, the image quality starts to deteriorate, my sharpness comparison will hence end here.

    Sharing of low light shots this evening at Little India, didn't find a need to use more than ISO800, the lens is just so bright. Slight adjustments on Lightroom, no sharpening was added .

    After having this 25mm Pro lens for a couple of week and close to 1K shots with EPL8 and Pen F, here's some thoughts as a summary.

    - Sharpness is fantastic, from wide open, from center to corners. The corners sharpness separates the Pro lens from mZD Olympus 25mm/1.8 (which is a excellent lens in it's own right). F4/5.6 is the sweet spot.
    - bokeh, find it to be very pleasant, has yet to have a situation of harsh bokeh even with messy background.
    - built quality, as with the Olympus mZD Pro range of lenses, the build is top notch, and with the weather sealing of Olympus, this would surely be a robust addition for those who require the build in harsher weather conditions. One thing though, is that the manual clutch mechanism is quite a bit larger than other Pro Zooms, and i tend to pull it to manual focus position easily, and hence the lens doesn't focus when camera is turned on. Probably the way I handle the lens change as well.
    - CA, there is some slight CA on very harsh situations, for such a bright lens like this, it's really well controlled, compared to Nokton 25/0.95 which I have as well, this is much better.
    - Weight and size, pretty big for a M43 prime, though it's still well balanced on a Pen F.
    - Nice starburst when stopped down.
    - Not much issues with distortion
    - AF is very fast, as with all the newer Primes from Olympus

    Please feel free to let me know if you have any further questions. Thanks for reading.

    Will be continuing to post more shots when I can.
