Several impressions/observations follow in sections. Unlike what I did years ago of getting a camera to test in several ways for specific things with charts and files, I am just going to comment on what I find as I find it relevant to things I want to do with it for several reasons.
first- quickie impressions as I am about to had out and try some real world scenarios
- camera is solid nice grip for as small as it is a/b level feels like it could break somwtime though
- quietest shutter of any camera with such I have seen so far this one surprised me
- camera operates pretty fast in responsiveness
- aF looks promising for the scenario I have in mind
- no ibis noise I could hear in a normal quiet room unlike the first model in this series
- ibis does seem as crazy as what the previews were saying though to me more of 2-3 solid stops (which is like Beat I have seen for a general ibis)
- ISO 5000 looks pretty reasonable (so far)
- dr is good seems like newer sony sensors (it is a sony sensor right?) that there's more shadow range than highlight - a matter of exposing to the right
All of this may change in some nuances- as I get to play more with the camera.
ISO 8000 (1/125 F1.8, so like 1/45-1/50 @ f2.8)
Converted from RAW (Iridient), no heavy noise reduction. The JPEG version isn't bad, but the glowing letters "Walgreens" (red middle right) have color artifacts/burn, while the RAW does not.
Improvement over OMD EM5 1.0 - no banding in shadows. The first model had some banding once you start hitting ISO 12800 (very well controlled) and shadows pushed past that (not horrible like the older Panasonic 4/3rd sensors but it's there). I don't see any banding here.
Auto - focus
The Autofocus works pretty well and the camera would lock even in pretty low light though it slows down but still reasonably fast for the light it is.
What I noticed though is that pretty much any attempt to follow any objects that are coming towards me/away from me in this light usually resulted in a miss-focus. Need to see how to do the continuous AF - tracking for this model, but a couple of things I tried didn't quite work.
Static or mostly static objects is another story. Or objects that would keep their distance from me to them even if they are moving left/right, up/down.
Auto focus update - tried setting the proper C-AF. When shooting several shots (5 fps- "low fps") I was able to get some shots in focus at night. This is a tough situation, and I felt the C AF worked in a couple of shots.
When doing single shot acquisition seems like it wouldn't quite work but if you "pump" the shutter while following the object you would increase your chances of getting shots in focus.
