Well, talking exclusively about wildlife photography, I think we have a great idea. More FPS will help capture peak action, and the continual march of more efficient computer processing and refinement of AI will result in better AF. But (1) the vast majority of wildlife shooting scenarios became child’s play for AF systems back in the D5 days, and (2) we’re going to need new storage technology to take advantage of those increased FPS. So, outside of BiF, the AF improvements will likely have a negligible effect. And even within BiF, I have serious doubt that there are standard deviations of improvement left to be gained beyond shooting small fast birds like swallows. Concerning the FPS, I don’t think that keeping up with 120 fps for more than 3 seconds is in our short term future, and probably not in our medium term future, either. If the buffer fills at 1-2 seconds, that’s not going to revolutionize wildlife photography. It’ll result in more options for peak action, if you can time it correctly, but it’s not a revolution. Now, that being said, I’m not one to bet against the market economy. So, suteetat is likely correct that we’ll get a new technology to take better advantage of the increased FPS, but I’m dubious that will happen over the next ~5 years.
So, again, very interesting technology, but I’m not optimistic that we’re on the doorstep of revolutionized wildlife photography.
In many situations it is not the latency of the current technology systems that is the major cause of missing the peak moment. It is human reaction time caused latency that has the biggest impact. I was once part of a study of athletes to determine reaction time, and ways to improve it.. Pro athletes have a reaction time of at best, with training just under 20o milliseconds. This is much quicker that the average human reaction time of over 250 milliseconds.
With a Global Shutter system that shoots with zero sensor latency, at 120 fps, with a pre-capture of 1 second, and a buffer of 1.5 to 2 seconds we can largely mitigate the human latency problem in the photography of very fast moving, short duration events. This has the potential to greatly improve the results in such pursuits.
It is not just BIF (although that dominates this forum), but many other things that will see positive improvements. It will not take 5 years either. It is happening now, and will go quickly at the high end from here.
This is not the only advantage of GS. There are others involving lighting, freeze motion without lights to call out a couple. Some benefits will take optimizations of supporting equipment to fully realize. But it is happening now, not in the future.
