Me neither. But I am curious as what's missing. Personally, I don't see a stacked sensor as imperative. It brings its own set of compromises along with it, about the only real advantage I can see is the faster readout, but if you can't get your shot at 10 fps then I think you might have bigger issues than rolling shutter in certain scenarios.
The reason it's important for a pro is that they don't want warped shapes in the their professional images. They want things to look natural.
A little more detail:
- No pre-capture in the 10 fps mode.
- Also, with zero-blackout, the screen is always one frame behind what's actually happening. Not so bad at 40 fps, but I could see that being a problem at 10 fps. Harder to compose as the bird/athlete moves around the frame.
So you end up needing to use 40 fps (although I hope the 20 fps rumor turns out to be true), which uses the electronic shutter. Which gives you warped geometry when things move quickly because the non-stacked sensor updates too slowly.
To be fair & forthright: I don't know how bad it will be with the S1RII, but I'd like to know before I pull the trigger. I want my next body to handle things that move fast reasonably well - both from an AF standpoint and from an IQ standpoint. I can put up with some distortion, but for a pro, I suspect this would be a hard pass.
Buffer -It don't even know what the S1R 2 is to be perfectly honest
It's small, at least for 40 fps. I think it's good for about 3 seconds. And given that the pre-cap is 1.5 seconds, that doesn't give much time for after you press the trigger. Also, it takes a long time to empty the buffer, and you can't start shooting again until it's clear. Just like the G9II. So you grab three seconds of action and then have to wait 15 seconds or so. Not good, at least for a pro. Now at 20 fps it becomes more workable. But still you have to wait. Anyway, you asked why people believe there is still room in the L-mount lineup for a pro sports body, and this, I believe, is one of them.
I think the less comprehensive lineup of super tele's in L mount would be the bigger hurdle myself, but it looks like Sigma is addressing that, at prices that aren't out of reach even for a serious amateur. I think one would be a bit harsh to criticise them for that however, as you start getting into the chicken/egg scenario.
Yes, agree on everything there.
Just a few of my thoughts
And a few of mine.
Again, it's early days. We will learn more in the coming weeks & months, I'm sure. Particularly on the effect of the slower sensor on fast moving pans & subjects.
