Rolling shutter effect with maybe 20% of shots. 80% no problem.

Not bad for 'cheapo' camera with 'cheapo' zoom and 2x TC.

In terms of rolling shutter/readout speed, how would you say it compared to R5 & R6?

Sorry, no idea. If I have shot a burst of 10-30 frames, it is no issue for me if 80-90% show no rolling-shutter effect.

Pretty impressive Tony. Canít wait to land one.

For context, the R7 + 100-400 lens cost only $2,100. The R5 + 100-500L lens cost $6,800. For posting on the internet and social media the R7 + RF 100-400 lens will do a better-than-average job Ö if you have the skillsets. The higher-resolving RF 100-500L lens will get you even more sharpness and resolution/detail, which is great if you are having to crop the image.

Or just go right down the middle and use the EF 100-400 II, great sharpness and middle cost tier.

The R7/100-500 doesn't like dark subjects and struggles to focus. The spotted towhee is one of the few.

This shot tests the cropability of the R7. This is a significant crop

I wonder if increasing the exposure by +1 or +2 will help to brighten up the shadow areas and improve on the AF acquisition.

The Rolling Shutter effect is a huge reason why I haven't considered making the jump to a mirrorless body. Can someone explain to me, why it doesn't appear on all photos? If it happens to one shot in a burst, shouldn't it happen to all of them? And this is only when using the electronic shutter, correct? The mechanical shutter eliminates this effect?

I apologize to all - I've been trying to wrap my head around the "rolling shutter" for about 8 months now, and just can't seem to get a grasp of it.

Yes, mechanical shutter or electronic first curtain shutter eliminates rolling shutter effects. He is likely only seeing rolling shutter on some frames due to the nature of his subjects. You mainly notice it when there's something in frame that you KNOW should be straight. The same thing can happen with a fisheye lens. Shoot something natural with curvy lines, crop in a little, and many may not even know you used a fisheye. But shoot a telephone pole or brick wall near the edge of frame and everyone will know.

There would be no difference in rolling shutter between DSLR and MILC when using mechanical shutter. There can still be some rolling shutter present when using MS if the shutter speed is faster than the flash sync speed, because the entire shutter is not exposed at once (someone correct me here if my facts are off).

Now when we go into electronic shutter, the readout speed of the sensor will vary depending on the camera. In cameras with stacked sensors, like the Z9, the readout speed (i.e. the time it takes to go from reading the top line to the bottom line) can be very fast, making the rolling shutter effect essentially equivalent to that you'd see with a mechanical shutter. Readout speed is affected by a few factors, but generally, cameras with stacked sensors have faster readout speeds.

If the readout speed of the sensor is much slower, say, 1/30 second, then that means there is a 1/30s lag between when the top line of the sensor is read vs the bottom - so if an object is in motion, it will look skewed.

Hope that helps.

That is not the same as rolling shutter. That is the light from the flash not synching with the opening of the shutter.

Right, I'm not saying it's the same concept. But the flash sync speed is the fastest speed at which the shutter fully opens; any faster, and the sensor is partially covered at all times during the exposure, which can look like skewed moving objects in the final image.

Yes, I do. I've read that. I've searched this forum and others. Read reviews. But thanks for assuming that since I can't wrap my head around rolling shutter, that I am automatically too stupid to do research on it. I'm sorry to have asked a question on your post. Won't happen again.

Thank you both for the information. While I think I am understanding some of this, I know I am not understanding all of it.

Not my fault that you make assumptions about a simple question I asked you, and went to the trouble of showing you how you can find MANY more explanations through Google than you can here.

Yes, I do. I've read that. Read what

Chill out.

I suspect that if you use mechanical shutter you get it all at once, all the data in the scene. Closer anyway

Electronic shutter, are you familiar with video at all? It goes more line by line I guess, especially interlaced. Taking more time to capture gives the motion in the subject. Though each part of the sensor may actually only be exposed 1/2000 or the ss you set

Some distortion even on film since at high ss you had a slit of the shutter exposing the film. Not all at once
