I don't have the camera in hand, but I found it in the detailed manual. P 306, "Display Simulation". In addition to the Exposure simulation, Exposure+DOF is offered also. I will try that now and see if it truly does what I thought.

A few minutes later - Yep. This option makes the camera always look through the lens stopped down to shooting aperture.

OK, so I put enough TCs on a lens for f/192, and the R7 did not focus, but hunted, when pointed at the light on the edge of a cloud around dusk, and alternating with a silhouetted tree line. Backed it down to f/108, and it focused on both, when alternating back and forth, and much faster than I expected. It may work at f/192 in full daylight.

And people thought f/11 was a miracle!

Later edit 7/31 : It was actually opening the aperture during focus; I didn't notice at the time.

I think I will adopt Gregor's term 'thermal blur'. AKA heat shimmer, heat waves, mirage, atmosphere, and a few others I can't remember.

Here is a case where thermal blur is pretty well guaranteed. Sunny day, road surrounded by grass. Good demonstration shot as subjects at various distances show more and more image dgradation. The number plate on the front of the truck does show some of the effect but fairly subtle in this resized image.

I noticed that they were driving ON THE WRONG SIDE OF THE ROAD!

Not only that, the driver is in passenger seat.

When I was in Sydney Australia I noticed one thing, here in the states when we are walking and come face to face with someone we step to the right without thinking, down under they step to the LEFT!

The important thing is to look to the right before crossing the road. That's a bad newbie mistake.

A couple from yesterday.

Did you do something different with processing? Everything, including the foliage, is blue on my laptop, which hasn't had any changes to its color profiling..

You are right!

Now everything looks blue to me , even the CRAW untouched looks kind of blue. I looked back and the tint slider was off on the first one, so definitively an "oops" there. Not sure about the second, couldn't find anything color related. Just toned down the "Auto Tone" .

Here is another one with a slower shutter speed.

Catch of the day

feeder birds

I see some artifacts, the left hand bluejay's beak is missing and on his left wing it looks weird.

is that due to the 30 fps ES?

One of the residents in my garden pond

It appears to me that the right wingtip is covering the end of his beak. I don't see anything overly distorted in this image to my eyes other than what's caused by the shutterspeed.
