    Snap focus & hyperfocus

    The snap focus is fun, pull the focus ring towards oneself, changes the mode from AF to MF without any setting changes. The dampening of the focus ring makes it feels like a real manual lens, unlike "focus by wire", for those who own the Olympus mZD 12mm/2 will feel right at home. And it also has focus limiter at both which is great, again unlike focus by wire which will just keeps on turning...and turning...

    The distance scale seems accurate so far, however...

    There's 2 possible flaws found though with snap focus.

    1. The focus limiter is not at infinity, one can turn it beyond infinity, unlike manual lenses, focus limiter will end at infinity. This happens to be same for Oly mZD 12mm/2 as well. Flaw for me perhaps, Olympus seems to think otherwise. I doubt the final production copy will correct that. Top picture shows infinity focus. Bottom pictures focus beyond infinity.



    2, Set to Hyperfocus, the depth of field scale (with aperture markings) seems too conservative. At F5.6, hyperfocal distance should be 3.42m. & At F11, hyperfocal distance should be 1.72m. However on the scales, it doesn't seem so.

    At F5.6, it shows much more than 3.42m.


    At F11, it shows close to 3m (which in fact should be 1.72m)


    The DOF scale if can be corrected would be easier to use, even though if not, hyperfocusing still will work, tested quite a number of shots with it, just conservative.

    A test of hyperfocus at F5.6. It works though as mentioned on earlier post, rather conservative. Can see the guy in front is out of focus (about 2m), while lady (about 4m) and far background is in focus.

    From the look on OMD, it looks very well balance in size.
    it should looks nice on my silver OMD. Thanks for the pic.

    Was testing the flare, it's very well controlled so far on the shots I had made.



    Colors of my son's feet are well retained,

    Distortions

    I haven't seen anything on jpeg that worries me, and can't find much time to compare the Raw files. From other reviews I had seen the barrel distortion seems quite bad, but for the size that we get with m43, there's certainly some tradeoffs.

    Here's some jpeg files on uncontrolled environment.

    F6.3, ISO200


    F5, ISO200


    F5, ISO200

    Quick review and wrap up after 2 weeks with this lens, note that it's v0.8 pre production set

    Likes so far:

    - Fast & very quiet AF
    - Distortion free (jpegs)
    - Resistance to flare
    - Quite close focus, good for food macro at least
    - Light weight, small, metallic built.
    - Snap focus
    - Pleasing bokeh
    - Versatile lens, certainly designed for street with it wide angle, shallower depth of field than 17/2.8 for portraits, some food macro, landscapes...
    - Importantly, looks great with the pen (ok, this is subjective as I love the Pens!)
    - CA, so far so good

    Dislikes

    - No hood bundled!
    - DOF scale is conservative, very tightly spaced.
    - No F8?
    - focus throw for manual focus is rather short
    - Find the sharpness not as good as 20mm F1.7, again it's v0.8, and I heard that v1.0 pre production gets a improvement in this. can't verify further, perhaps someone who had it can review again later.
    - Manual zoom rings a little flimsy.

    That's all I have so far, hope this is helpful for some

    The hyperfocus markings are borderline useless..... couldn't they do a better job on it? The ones on the manual lenses i have are way more usable.
