High ISO madness
OK, feeling a bit bored this evening, I decided to try out my K-5IIs and Canon 6D at ISO 51,200, a speed I rarely -- OK, never -- use.
Being as it's night out, I photographed a fascinating shelf full of backpacking gear in the dimly lit shop building.
Lenses were the Pentax 16-50 DA*, at 16mm, and the Canon 20-35 L, at 26mm (OK, I thought I'd set it at 24mm but missed.)
Cameras were set to Av and f/4, and both picked 1/200 for the shutter speed. Images were converted to BW in Lightroom 4 using the same home-rolled macro I generally use on landscape shots.
Results were fairly predictable. The big surprise to me was that the Canon image appeared better exposed; you can see in the images below that the shadows are a bit blocked in the Pentax image. Presumably I could lift them some without damage.
I also -- and you can see how bored I must be tonight -- made 20x30 prints of each. Canon came out a bit finer grained, but the Pentax is not at all unpleasant. I actually like the look of both, and I may start using ISO 51,200 on both cameras in real life. The actual prints from both look better, even from a couple feet away, than these web versions.
OK, now on to some actual work....
And then Canon:
