View Full Version : E-M1 vs E-M1ii - noise at ISO 1600

I downloaded the E-M1ii and E-M1 sample raws at ISO 1600 from the Imaging Resource site. Using Viewer 3, I then converted them to tifs using default settings and imported them into LR 6. I then pushed shadows to the max in both. This is the result (E-M1 on the left, E-M1ii on the right):

There's definitely less noise in the E-M1ii image and since it's a little larger too, it'll get better when downscaled. Some good news! (unless my method is flawed!).

That looks convincing to me Paul. *yes

Thanks Paul, that certainly looks like a worth while improvement when coupled with the step up in resolution.
Damn, the more I read the more this is growing on me, still too expensive though :(

Can you get rid of the chroma noise and post them again, resized to the same resolution?

Interesting comparison, thanks. For most practical purposes (press, web etc.) I find 1600 quite usable on the Mk I so any improvement here falls into "nice to have". What I would really like to see is improvements at much higher ISOs like 6400. Do you know if there at comparison files for that? (I know I could google for the website but if Paul can just post a link or knows the answer already it would make life easy :) ).

I was looking forward to the new model, I enjoy the predecessor which I bought second hand for around 900. But all the I could afford the new model, but, I can't see around 800s worth of difference for my usage.

Here is at ISO 6400, only chroma noise removed and no sharpening
3743

3744

I lifted the shadows a little but not full, and tried to balance the WB on the white box on the color test chart. Definitely an improvement, for sure in part due to the increased resolution.

Downloaded, converted to tiff in Viewer 3, edited in LR6, exported, resized the Mk II to 4608 px width, cropped both and converted the crops to jpg.

I've been playing with that site as well - on older cameras as that is what I have

downloading them and just resizing the JPG files to the same size as the E-30 files there is of course an incredible difference

The 12800 was a clear winner over the E-30 the 256000 was cleaner, but not looking as sharp, but a USM filter 20/radius 5 brought it back and still showed less noise

Hmmmm ... how will I justify this ?

Thanks Dan. For some reason it won't expand your images but I found the website and have had a quick look. I'm not really sure what conclusions to draw, really need to download the samples and have a play. And of course there is no substitute for trying it out in battlefield conditions.

Funny, on my computer they expand normally. Here is a link to two other copies:
