Tom, the reviews - for what they're worth - all seem to point to rather poor high-ISO sensor performance. Could you explain how you managed those two excellent ISO 800 and 1250 images? Any specific work-around on noise filtering?

Mark,

I think one thing you have to comprehend is that EVERYONE HAS LOST THEIR FREAKING MINDS!!!!

For crying out loud, people are negative about this, negative about that, and they will let one meaningless specification keep them from buying truly EXCELLENT cameras.

Here is my simple perspective, from using somewhere around 60 digital cameras, from the very most bottom-of-the-line compact through Micro Four Thirds though APS-C mirrorless, through Canon APS-C DLSR, and to the current crop of larger-sensor, fixed-zoom-lens cameras:

I am much, MUCH happier with the results I get from the Canon G1X Mark II than I have been with any camera I have ever owned.

For most of the shots you see above, I simply used "P" mode, with Auto ISO and Auto White Balance. And that includes the two low-light pictures. Just P mode, point and shoot, and excellent results.

For the outdoor plane shots, since they tend to have wings going out to the extreme edges of the frames, I switched to Aperture Priority mode, and used f/8 to make sure everything would be in focus.

And finally, for the Spruce Goose in its building during sunrise, I switched to full manual mode, and changed the shutter speed as I shot over and over and over again, hoping that one shot would come out better than the others.

But, back to the two dark shots. Here are a few more:









Again, all of these were taken in P mode. As for "High ISO" shooting, I think this room was about as dark as I'm going to wind up shooting in, and with the G1X Mark II's "fast" lens, I don't think I got into "high" ISO numbers at all. I consider "high" ISO settings to be ISO 3200 and above. And I'm not much of a high ISO shooter -- I set the Auto ISO upper limit to ISO 1600, and I've rarely even touched that.

The only other settings I've changed is the in-camera sharpness -- I found the G1X Mark II to have less sharpening than most other cameras I've used lately (can you say "Sony"?), so I've cranked the sharpness all the way up in the G1X Mark II's "My Colors" settings. But that's the only adjustment I've made.

In post-processing, I don't usually do a lot of work -- I like to try adjusting the levels a bit (brightness / darkness), and I can usually make things a bit better with that. Otherwise, I always crop and resize to my monitor's 1920 x 1200 resolution, then I use a very small amount of unsharp mask at the end before saving my final versions. I have done NOTHING to work on "noise" whatsoever.

If you've read much of my postings lately, I've recently bought the G7X, but I've got to say it has been slightly disappointing -- while it is a fine camera, there is no doubt that the G1X Mark II just easily beats its image quality. It may not be "by a mile," but if you want better image quality, it's well worth going for the G1X Mark II, instead. I absolutely could not recommend it more highly.

Hahaha, I enjoyed that, Tom.

Thanks for the rest of your post too.

It´s the scene, and ones hands.

Sometimes you can get very clean shot at high ISO speed, sometimes you cannot. It has something to do with lighting and human perception of what actually noise IS and what IS NOT in the image. Sometimes I can shoot ISO 3200 noiseless image with APS-C sensor, sometimes I can see noise at ISO200 easily.

And there goes processing. I had many heated discussions about G1X II image quality, especially JPEG OOC image quality, and I´m pretty sure, that one can get even better results than what you have seen here in this topic (those are actually excellent).

So I´d say it´s extremely good camera, but it won´t work for you out of the box. You have to behave accordingly, treat it and operate it as a camera, not just a thing with button...

[/QUOTE]When judging noise one has to be awere that Tom resizees the images to match his monitor. Reseizing reduces the noise by a great deal when viewing at 100%. Someone smarter than me could probably work out by how much exactly but I would think that downsizing by almost 3 times would have a great impact. Jan
 
I wonder if it is possible that you got a good copy of this camera. I have the same camera but I always get issues with noise.
I actually have two G1X Mark II cameras -- I was so happy with the first that I bought the second as a "backup." In comparison to each other, I didn't see any difference in "noise" or overall image quality at all, though I did see that the first one had a very slight blue cast to its color, while the second one has no color issues that I can determine at all. So, I just moved forward with the second one, leaving the first one home as a backup if I ever need it.

But again, I don't see any differences otherwise, and certainly not with "noise."

You could explain to us in greater detail the "noise" you see -- do you see it at the lowest ISO settings, or the highest ISO settings? Do you see it while "pixel peeping at 100%," and not while viewing images at "normal" sizes? And so on.

I don't do anything to "work on noise" in post-processing -- I haven't touched it in any of the G1X Mark II images I've posted to this forum. But, I do a couple of things while shooting that might help:

1. I have set the "Max ISO Speed" in the Auto ISO settings to 1600 -- I'm just not interested in using ISO speeds above that, except in extraordinary situations.

2. I use "P" mode for low-light shooting instead of Aperture Priority mode -- not only do I expect "P" mode to give me the best combination of shutter speeds, aperture settings, and ISO settings in such conditions, but I am also aware that, just like has been written about the G7X, Aperture Priority mode uses HALF the shutter speeds as "P" mode does, thus requiring higher ISO settings. Of course, you could go to full manual mode and take care of everything yourself, but it is wise to be aware of the differences between "P" mode and Aperture Priority mode.

I'm not so much in agreement with that. The low-light pictures I have posted (from the Museum of Flight in Seattle) weren't taken with a whole lot of "work" on my part. I just used "P" mode, with Auto ISO and Auto White Balance.

The only settings I actually chose were to bump up the in-camera sharpness, to use the center focus mode, and to keep the Auto ISO maximum setting at ISO 1600. And I didn't do a massive amount of work in post-processing, either.

Beyond that, I mainly just tried to "fill the frame with a subject," and, as usual, I used exposure bracketing and took several bracketed sets of each shot, so I had perhaps a dozen different shots to choose "the best shot" from.
