    This lens was available early 2017 with MSRP of $350 (as pointed out by a fellow member @madogvelkor the lowest seen so far is $169). It has a focus lock screw to lock the focus for adjusting aperture and drone applications (at 110g it's lighter than the Laowa 7.5mm f/2). Aperture is continuously adjustable from f/4 to f/16. Here are a few SOOC jpg pictures from my E-M10 II for you to check out the image quality unfortunately I couldn't remember which is at f/4 or f/5.6. The picture of the bay is probably at f/8 but again I'm not sure.

    One thing to point out is that the focal length is about 8.5mm (using my Olympus 7-14 f/2.8 as reference).

    Picked up a graduated ND filter with 52mm thread - never used one before but I figured I'd give it a crack with the 8mm SLR Magic.

    Just very basic auto-enhance on the raw file in Aperture.

    First is a 'before'


    Second is 'after' the filter - clouds/sky look a little better but could do without the corners

    Spring is here!

    I thought this was a fun use of the way UWA lenses emphasize a foreground element while bringing in a broad sweep of background.

    E-M5, f/8 I think, 1/125s, ISO400

    The aperture isn't clicked, so this is somewhere in the neighborhood of f7, SOOC.
    Lens seems to have really punchy colors and no vignetting.

  10. Where was the focus set? The right hand side railing looks really blurry, even at web resolutions...

    Focus is at infinity, which should be about 1.5m+. But the focusing is really weird, so I might not have been perfect. It's not a particularly sharp lens, though. Pixel peepers beware.

  12. I guess the railing was possibly too close then.

    My copy focuses to infinity at exactly "1" (m) mark. I confirmed that very carefully with 14x magnified focus preview at EVF.

    This lens seems to be quite sensitive to focus error. Focus adjustment almost feels like a microscope focus drive (image won't be in focus properly, if focusing is off).

    I leave my lens at 1m and locked focus there. Subjects from about 1.5m to infinity are in good focus, at around F/7-F/8 (which also seems to be its sharpest aperture).

    For subjects at approximately infinity (>1m or so), my copy is sharpest at the hard stop.
