Last night I shot a nice Wasatch sunset with the new Canon EOS-1D Mark IV and 70-200 f/4L IS lens. It was a nice combo. Between the great high ISO image quality and the light, image-stabilized lens, I could shoot the whole thing without a tripod. Nice, for a lazy photographer
As you'd expect, at ISO 100, the 1D Mk IV is super smooth and beautiful. I also shot one at ISO 1600, well after the sun was down, just to see how the noise would look. I pushed that one over one stop in Lightroom and I think it still looks pretty damn good. I will upload it to the gallery at 100% so the pixel peepers can take a closer look. I'll post an ISO 100 sunset photo at 100% in the gallery, too.
If you want to see more Canon EOS-1D Mark IV sample photos, take a look at the high-res studio samples taken at all ISO settings. You can also look at all Canon EOS-1D Mark IV photos in the gallery. There aren't many yet. I'm just getting started with this camera.
