I didn't export the EXIF, but the settings were the same as I mentioned in my OP. Nothing changed in my settings.

That's an excellent question. I was using Evaluative metering (I'e updated my original post to reflect same).

We went to the State Fair rodeo yesterday. I was using my R5 with the EF 135 f/2 at f/2.0. For these two images, the ISO = 400, f/2.0 and shutter speed 1/200. NOTE: I was using Evaluative metering. Setting aside that the shutter speed was too low (I upped the ISO & shutter speed later), but just looking at these two images, any idea why the second image looks blown out?

The histogram is shifted well to the right and there its a spike up against the highlights. This was the sixth in about a 30 shot set using servo and High Speed (mechanical) shutter. Exposure on all the other images looked normal. I don’t think there was any change in the lighting nor anyone near with flash.

Just wondering if anyone has any idea what happened here? (The settings were exactly the same for all the shots in this series).

Same settings but way over exposed.

For some reason EFC on my R5 is slightly louder than mechanical. (See my dB meter test above). My old ears could not tell the difference

My old ears can't tell the difference between the two either. See my experiment above where I found that mechanical shutter was actually slightly quieter than EFC (not what I expected).

From watching the video I posted earlier, with Rudy W, there don't seem to be many cons to using Elec. First Curtain. I think I'm going to give it a try.

Just for fun, I tested Mechanical vs Elec. 1st Curtain on my R5 and the difference in shutter sound surprised me. In fact, I tested the shutter sound with a DB meter and the results were not what I expected. If you can believe these charts the mechanical shutter (at least on my R5) was actually slightly quieter than elect. 1st curtain. This surprised me because even Rudy Winston, in the video I posted, suggested the Elct. 1st Curtail would be slightly quieter.

I tried this test a few times with same result. The first image shows the setup. I located the mic on my iPhone just under the lens, near the camera base (close to where the shutter is located). As you can see from the 2nd and 3rd images, the shutter sound for the mechanical shutter was slightly quieter than Elec. 1st Curtain. Note: I'm calling the lines above each number on the chart the corresponding dB level. Not sure if that's correct, but for comparison is doesn't matter as the difference in dB is relative.

Mechanical Shutter: First = 72dB, Second = 70dB, third actuation = 65dB

Electronic First Curtain: First = 75dB, Second = 73dB, third actuation = (about) 66dB

You might find this instructive.

Note, when I tested Mechanical vs Elec. 1st Curtain on my R5 the difference in shutter sound was very slight.

Indeed I did. Hope to go out again, but probably not this year.

Agreed. We didn’t, we did, we did (including AllTrails), we did, we didn’t. You’re right about no signs and no trails.

I think my flat tire was caused when I ran over probably a screw because it was a nice, small puncture and I could see the indentation of what was probably the head of a screw in the tread. Fortunately that tire was repairable. Then other fellow's flat tires were not nice small punctures, but look more like he may have hit some sharp rocks too hard. Neither of his tires were repairable and he had to buy two new tires.

Moral: If you go to this area, drive slow over the rocky roads there.

Thank you!

Thanks!

UPDATE: I can’t believe it, but they had the award ceremony today and one of my images, (L6 in my initial post) won first place in the Adult Amateur-Scenic category. First time ever entering a contest and can’t believe I actually won!

Hey, don't give up on the place - I ain't no spring chicken myself!
