Thank you for posting the tests.
Am wondering why the images are not sharp. Thx.
I'd venture they're not sharp because I was well beyond the lowest shutter speed/focal length where the IS is able to deliver. Combine that with medium focal length, relatively shallow DoF, any bit of motion is going to cause some blurring. Add in the level of way late night fatigue I had there was no way I was going to be as steady as I could have been either.
None of the images were sharp
, motion blur seems to have gotten most of them far more than the in-camera NR for loss of detail.
The first 2 shots with the 7d2 were at 1/4 second and 70mm - that's between 4 & 5 stops slower than would be recommended as a slowest shutter speed for that focal length to have a reasonable chance of a clear image and likely a stop or 2 beyond what most IS systems can deliver.
The 3rd shot was at 0.4 seconds so nearly 1 stop slower yet. I'm not sure if there was also some breeze-induced motion on the leaves there as some are much more blurred than others. It was just hard to see and judge focus on top of that.
I've now scaled the Fuji and Oly shots to similar size for comparison.. (hmmm.. musta been a late nite, couldn't even keep my landscape=portrait orientation consistent!)
The reason I even started this test was I noticed the 7d2 AF acting unexpectedly in some low light indoors situations. I was merely playing with the lens to see what its close-focus abilities were like. I was aiming at a bright stripey textured throw rug with lots of color and contrast and well within the min focus distance when I found the 7d2 refused to AF. It would just hunt, with in-focus quickly passing thru as it racked each way. None of my ML cameras had any issues with this and I don't recall any of my other SLRs struggling with such a focus target. I'll test more if I have time in the next few days as I was puzzled and not impressed by that example.
I can't repeat these exact tests as we just had a dump of snow so the lighting and targets are now quite different.
