Anyone familiar with Olympus cameras is aware of their inferior performance at high ISO's relative to other brands. Normally I hardly ever need high ISO and I was comfortable shooting at ISO 1600 with my E-PL2 which is what I settled on when we went to the Taylor Swift concert last year.
The OM-D's high ISO performance is greatly improved, maybe due in large part to the Sony sensor. When we were on the Big Island last month, I inadvertently switched the ISO to the OM-D's highest level - 25,600! I still don't know how that happened.
It was a while before I realized what was going on.
Here's a shot SOOC of a wildfire we encountered trying to get to a black sand beach.
I took a few of the pictures to try and see what I could do with them in Lightroom, and while I won't be shooting at 25,600 voluntarily again unless absolutely needed, I was pretty impressed with the results after a bit of tweaking. I have the high ISO limit set to 6400 normally. Here are a few after I played with them a bit.
Here's one I took when I switched the camera to iAuto mode because the ones I had been taking (not knowing they were at 25,600) were looking washed out. I was walking through the tide pools at Turtle Beach in Kona so I had the 12-50mm lens with me so I wasn't worried about it getting a bit wet. I didn't have a polarizer for this lens at the time (got one yesterday) so I took this with my sunglasses held in front of the lens.
