Canon R8 Canon R8 Rolling Shutter

Dcweather · Nov 9, 2024

More of an example than a question. Two shots from the same burst at one below max rate H+. Card not that fast V60. One with rolling shutter the other ok. not a major problem but does illustrate it well for those who have not come across it before. As you would expect more prevalent in my R7 than the R8

That body is not in the R1/3 class so not surprising. You gotta spend the dough to control that flow. I just made that up. Kinda dumb but true. This is kinda old but a good visual. These values were an estimation from one of Duade Paton's videos but pretty close. No R8 here but see below.

Here is link that is more current numbers. In the upper left you can change the display numbers to milliseconds. The R8 shows 14.75 which is better than I expected but still not an R3 that is 4.79.

This is why I still use the mechanical shutter on my R6 mkII, unless I'm in a really quiet environment.

I shoot EFCS with my R6II which doesn't completely negate the problem. I'd have no issues using mechanical. I shoot exclusively using ES with my R7 because I can't stand the jack hammer shutter and deal with the results. I'll be keeping my R6II around. Sweat camera. I'm looking forward to what Canon with the R7II, if they ever release one.

For an R7II to eliminate its rolling shutter it's going to need to double in price, at a minimum. The R7 is under powered as is, even with the rolling shutter. To make it what folks want you're likely looking at a $3500 camera that will be worth every penny to those who want one.

You nailed down. It's all about the price. The R7 could have been a wonderful camera but they decided to cut corners everywhere to release it at an appealing price. As result you got a very noisy pictures, a pronounced rolling shutter issue and unreliable AF (this one partially caused too for the slow read out speed).

As the companies get the ROI back tech trickles down to lower end cameras. If they don't do that someone else will. Look at the AF for entry cameras today compared to 6 years ago. This may not happen by the R7II but it will one day. One day all cameras will gave global shutter. That is a long ways off but it will happen.

I'd gladly go with this and shoot with mechanical but I don't think Canon will proceed.

Very interesting video.

Yeah I' be happy with current pricing and using mechanical shutter with that tech. The reason I don't think we will see it us because that was 2 years ago and so much has changed. It's all about sensor tech. I'm not a manufacturing guru but this is headed towards global shutter I think. If I ran a camera company that's what I'd be doing. All you need is a shutter that closes to change a lens. No high speed shutter components which would cost less for the company and not have to warranty them.

I hope I'm wrong. Shutter tech is pretty solid but still the company actuary's add that into probably of failures and cost to repair.

Well, the most important thing is that Canon still experimenting. Global Shutter, electromagnetic shutter. whatever shutter. It does not matter.

This is true. Good point.

Bear in mind the R8 is cheaper than the R7 and has a pretty good read rate on the sensor, less than half that of the R7.
