Went to Hong Kong Disneyland yesterday.

Facing the sun around 2:45pm insisted on using larger aperture (against gut feeling)to try and get some background blurring, so used anywhere between f2.0 - 2.8 whilst attempting to keep shutter speed within 1/4000.

Result was lots of CA making pics generally unsharp...I really appreciate the FF in this situ. Need to use zoom and distance with m43 to make up for this somewhat.

As a bonus can confirm that my copy of the Leica definitely has af issues. Af somehow extends away from the af box with ONLY this lens. I don't experience this with any of my other 6/7 lens.

That is a known issue with the E-M5 when using very fast lenses - lowest ISO being 200 and highest shutter speed 1/4000 sec.

And I talked about this weakness a whole year ago while researching this camera.  Me bad, bad mouthing something I did not own and had not even touched at that time.  (How dare you?!)  

Well, As long as the OP (me) gets the limitations and doesn't lament that the camera is crap blah blah blah, everything is good.

I too discussed this earlier, and only got the cold shoulder / challenges from others regarding the issue with 75mm f1.8.

I'll have to chip in for a ND filter, but even so, I don't think this will fully fix the issue. Large aperture and bright light just don't mix I learnt from another thread.
