I got my 7D2 and 5D3 at about the same time. I don't have much experience yet with high ISO shots. I took the photo below with the 7D2, 100-400 II @ 105, f/6.3, 1/160, ISO 6400, handheld. When I first imported it into Lightroom, it was pretty grainy. But after applying some color and luminance noise suppression, the photo seemed to get much better. I'm still not sure if the noise level puts it in the "keeper" category or not. For those of you that do have experience with high ISO, is this shot ok? Thanks!

I like it. I have found that with my 6D that the noise from high ISO is somehow adding to the shot alot of times. It appears the 7D2 is no different.

Looks good at this size to me. I find that when I shoot high ISO with my 5d mklll, looking at them in Lightroom or Photoshop at 100% magnification, I'm often a little disappointed seeing the noise/grain that I can't quite remove. But when printed, the images are quite stunning.
I'm slowly learning to stop pixel peeping, step back and look at the whole image.

Heya,

What matters is size of image & quality of image, relative to the viewing distance.

Very best,

I agree with ThreeHounds and MalVeauX in that the photo is best evaluated under the conditions that will be used for viewing it. That said, I also like to see what's going on at the pixel level. In that spirit, here are two full-size images.

This one is exactly the same settings as the photo that started this thread:

And this one is with even more luminance noise suppression:

The only thing I don't understand is why you didn't use the IS on your lens to help you out? Looks like a still subject...and you shot at 105mm. This is crop so figuring 2-3 stops of help that means 1/40-1/20th a second should be possible. That would have let you use ISO800-1600 which would be significantly cleaner.

However, considering we are looking at very dark areas of the image at ISO6400...this looks about right to me.

Glad to hear the ISO noise looks about right. Thanks!

Your question about IS is a good one. I normally shoot birds and other wildlife. I'm usually at 400mm, and often have the 1.4 extender on. That's 900mm equivalent. The default settings of the 7D2 kept the ISO as low as possible by dropping the shutter speed to 1/125 or 1/160. My keeper rate at those shutter speeds was low. So I set the 7D2 to not drop below 1/250 until the maximum ISO had been reached. I'm much happier with my keeper rate now. Unfortunately, those were the settings in effect when I took the photo in this thread, and I didn't think to change them. Thanks to your reminder, I will be more aware of this in the future. :-)

At the large size the 2nd one is great

It's under the 2nd menu under camera settings under ISO Speed Settings. There's a menu item for Min Shutter Spd. Choose Manual and then choose the speed you want.

Thank you, so you leave ISO in Auto? and it says this only works in AV or P modes
