I also thought of som...Thanks for the quick reply!<br /><br />I also thought of some sort of fine metal mesh - similar to a fly stopper - but it would make no sense on a train light, wouldn't it?<br /><br />I also can't see a sturdier protective grid and it would be much too coarse for the moire pattern to develop anyway, IMHO, so some sort of "weathering effect" (looks a bit like sand dunes) on the glass - or between glass layers - could very well be it.<br /><br />Anyway, very interesting stuff you have here and I'll have you bookmarked.<br />All the best!<br /><br />Marcus Heusernoreply@blogger.comtag:blogger.com,1999:blog-2087926012757338143.post-59556085680117564142016-08-30T04:53:07.154-07:002016-08-30T04:53:07.154-07:00Hi Marcus, well spotted and in fact I had noticed ...Hi Marcus, well spotted and in fact I had noticed this when I was first preping the files, it is in both the Hi Res JPEG and the RAW. I don't think it moire, though initially I thought it might be, I suspect it is some sort of pattern created on the glass by the angle of the sun, I suspect it is a double layered lens and this is a result of the laminations between the two layers having aged, a bit like newtons rings. Anyhow I I would expect moire to occur on repeating patterns etc not otherwise smooth surfaces, at first I thought the light must have had some sort of mesh over it but when examining the 64mp files it was obvious it is just glass. It is a tricky one though and without a revisit I can't be sure, but I can say it is the only time I have seen this effect. braddlesphotoblurbhttps://www.blogger.com/profile/04086428650771390212noreply@blogger.comtag:blogger.com,1999:blog-2087926012757338143.post-47901236047095136982016-08-30T03:32:29.023-07:002016-08-30T03:32:29.023-07:00Thanks for your exhaustive article and the effort ...Thanks for your exhaustive article and the effort you put in it - very enlightening and great photos!<br /><br />I have an observation about color moire, though.<br /><br />You write that you have never had color moire with the HR mode on the EM5-II.<br />This matches with my own short experimentations with this mode but I really don't consider them conclusive.<br /><br />However, the 6th image shows a distinctive color moire pattern: In the front light of the blue-yellow train locomotive.<br />At first I thought it was dirt on glass or something like that but the 7th image and the following crop don't show this.<br /><br />Now, I fully agree with your observations that the slightest amount of movement ruins the sharpness of this mode (as in the 7th image) but this can also suppress moire patterns (while generating the other ugly patterns).<br />So if the 7th image is slightly unsharp it's likely to not exhibit moire and therefore should show the reason for the pattern in the 6th image - but there apparently is none.<br />As the 6th image appears to be tack sharp I can therefore only surmise that it has indeed moire.<br /><br />The big question is therefore where the moire comes from: The camera or your post production (reducing the image size?).<br /><br />Can you shed some light on this?

I don't think you need worry about the lens mount integrity, I have never had an issue with any camera lens combo. I will add this though, you should ensure the adapter you buy has an integrated tripod foot so when you mount it to a tripod it is properly balanced. I hope that helps, it is a stunning lens.braddlesphotoblurbhttps://www.blogger.com/profile/04086428650771390212noreply@blogger.comtag:blogger.com,1999:blog-2087926012757338143.post-2513487939919126212016-08-29T09:38:26.766-07:002016-08-29T09:38:26.766-07:00Great read, thanks for the work you put into this....Great read, thanks for the work you put into this. I am eagerly, eagerly waiting to see what EM1 mark ii can do with this feature, if it truly can do it handheld, that'd be revolutionary. One question I had, because I am thinking about getting the Sigma 18-35 1.8, how does it feel on a m4/3 body? I am paranoid that it'd snap the mount or something due to the weight difference between the lens and the body.Anonymoushttps://www.blogger.com/profile/02507953401874190554noreply@blogger.com
