If you shoot with an E-M5 and use high ISO (800 and higher), then remember
the 20mm - E-M5 combo suffers from quite severe banding! Please test first
Yes, test. Some people seem to have more trouble with banding than others. Whether sample variations, camera settings,
phase of the moon, or whatever, I don't know. I'm far from home, so can't check.

Maybe indeed only little. The 20mm was announced only 3 month or so after
the announcement of the E-P1. Panasonic had probably no or only a limited

Not quite so. I noticed it with the E-PM1. I got slight banding in the deep
shadows when shooting more or less in the dark.
I took some quick, casual test shots with E-M5 II last night, all at ISO 3200,
- 2/3 EV.
This was shot in a very dim room. Histogram only gets 1/3 of the way up. So the corrected version has been pulled waaay
up. I can't really tell brightness on this narrow angle screen, so I've included two different brightnesses. The lighter
one is closer to the original and the test for banding. I just can't see any that isn't in the original drawing.
Unevenness of illumination is reflections of me and stuff behind me.
This carpet is very poorly lit, with some light spilling through from another room, so it's dark, darker and darkest.
I've really pulled up the shadows, and there is certainly some banding on the bottom, the darkest part, but none
elsewhere. If for other than testing, I'd be using something closer to the dark version.
A very different subject, backlit with late dusk light. This has also been pulled up from underexposure, but doesn't
look it. I can't see any banding. <http://zone-10.com/tope2/main.php?g2_itemId=19024>
With this particular 20/1.7 and E-M5 II, I have to say that banding isn't a
so Olympus obviously had some time to take countermeasures.
I do wonder what they would be and what they would cost, both in $ and delayed production. I can see cost-benefit
concluding that special efforts to accommodate a minor problem with one lens are not worth it.

Very odd issue and reported early on with E-M5 but also seen on E-M10. There
are some reports of substantial lens to lens variation in the banding as well.
I've been wondering if Frank has a particularly bad one. I'm also curious about the second version. It looked to me like
a straight cosmetic redo, but could have included some electronic change(s), as well.
