Is it possible for micro-single to replace SLR?

I was a little puzzled about this question not long ago, because the technology of phase focusing with photosensitive elements has long existed. As for the physical objects, there were Fuji F305EXR before, followed by Nikon J 1 and V 1. This technology has been put into practical use, and all that is needed now is perfection.

Once the focusing speed that SLR is most proud of catches up with the single battery, it will have no advantage in the competition with the single battery.

Disagree with the second floor.

SLR has never developed, the technology adopted is not essentially different from that of decades ago, and the basic principle has not changed. SLR and SLR don't develop synchronously, and there is always one leader.

As far as I know, there are patents for phase focusing of photosensitive elements, all of which are slightly different. In principle, the accuracy of this technology should still be inferior to that of SLR, and it is not good in the number of focus points, which will have a little impact on the image quality (this is almost negligible). It's just that these problems are not critical and it's not difficult to improve. The most critical technologies have been overcome, and the rest are nothing.

I think, in another year or two, this technology will be perfect, and then the single battery will usher in spring, and the SLR will be gradually eliminated.

By the way, I don't think highly of Sony's semi-transparent mirror. It's so unreliable that it's equivalent to pretending to be a permanent grey mirror. This helpless technology can't become the mainstream.
