Yes! The defaults are sounding pretty good at this point, lol! I had a very frustrating time this weekend. I was working with a still life and using the tripod. Got the focus point on the screen but when I used the shutter button the screen went to the black Info screen. I don't know what I did. The back screen would not stay on for me. I looked at the Screen/Viewfinder setting and it was on the one that would switch between the two which should have been right. I tried all of the settings the screen kept disappearing. I ended up using the Reset button, grrr. That fixed it. I wish I knew what I had done to mess it up.

I also downloaded and installed the latest firmware. I've never done a firmware update but figured it would be easy. It took me forever! I kept getting the screen that says Update with "Cancel" and "OK" but "OK" was grayed out so I thought I had done something wrong with the memory card. The 3rd or 4th YouTube video finally mentioned that the "OK" might be grayed out and to use the back wheel to move to "OK", the touch screen won't work for this. Well, that was my answer. Boy did I feel dumb, LOL!

We went to the Denver Botanic Gardens last week for the Blossoms of Light event. I didn't trust myself with the camera so I used the Handheld Night Scene setting. It did okay, some of the shots had a really high ISO. This one is okay.

Good job!

Yeah, I seem to recall I also got that grayed-out OK button. But the upgrade went fine once I dealt with that.

The R7 is way more complicated than the R5, as reflected in the size of the compressed firmware files - 68 MB and 52 MB respectively. Understanding the camera is not helped by the nomenclature. Thus One Shot is not the same as single shot. Besides that, there are odd things like the camera continuing to track when tracking is turned off, and finding people when the camera is clearly set to detect animals.

I have the R7 sitting beside me at the computer as I go through the resource materials and the camera menu. Most likely I will drain the battery a couple of times before I'm done.

The upside is that the camera does very well even if the settings are not correct according to the book.

Here is a pic of a Mallard hen. R7 of course.

The high ISOs aren't necessarily the real exposure. There is a tendency for people and software to stack images, and claim that the ISO of a single one of those images is the ISO, but it is not. If four ISO 6400 images are stacked, for example, the real ISO is 1600, but claims of ISO 6400 "with very low noise for ISO 6400" might be made as if it were somehow miraculous.

Thanks for this, I wasn't aware.

Isn't random noise averaging a square root function? Not sure how it would apply here, but would guess averaging 4 images would halve the ISO.

Thank you! it was a delight to walk through. : )

You're applying photon noise math to exposure, where it shouldn't apply. What's the difference to photon noise if you expose 4x as long or use 4x as many exposures? The total photons is the same in both cases.

Very happy with this camera.

I hope so and will I stare at the sink for two hours?
