Canon Eos 6D mkII high iso

An example of a decent high ISO (12800) picture form our Canon Eos 6D mkII

I don't use photoshop or any other enhancement software other than Canon's DPP for our raw digital images
(do use Gimp for editing like scratch and spot repair for our analog photos)
So only basic lens corrections are used (when available) and all the standard in camera setting are applied to the images.

Very nice, thanks for posting. If you frequently shoot at high iso you may want to do a trial of DXO PureRaw, it does wonders to high iso raw files in terms of corrections, noise reduction and sharpening.

I also think 6D mkII has a very good high ISO image quality. Some say 6D MkI was better. I have both, no difference.
