Originally posted by photoptimist LOL! You do realize that all these cameras are just nichey little consumer electronics products. They are not nuclear weapons. The only battle here is in the over-active imaginations of a few hyperventilating internet denizens.
Meanwhile most of us just yawn about all these supposed "gamechangers" that really change nothing other than adding some pennies in the pockets of the click-bait sites. We just go back to taking pictures.
There is a real tendency for each of us to look at our own style of photography and our own needs and believe that they are everyone else's.
To me a lot of the improvements of mirrorless are neither here nor there. EVFs, in the end are just a slightly different way of framing your image. They have some helps which might make a difference if you are shooting manual focus lenses all of the time or just can't figure out how to avoid blowing highlights, but for most experienced photographers they are just a slightly different way of doing exactly the same thing. Probably the biggest thing that having an EVF on your camera does is that it allows you to lose your mirror and make your camera thinner. As we have seen recently, mirrorless cameras have increased in size quite a bit and while you can find quite small ones, many of them are approaching SLR sizes.
As far as video goes, I still think it is more of a box that is to be checked. People like surfar really do shoot a lot of video, but none of the folks I know who own shoot much video with their SLRs. Some wedding photographers are branching out into that. I just don't think it is as big a driver of ILC sales as what people here on the Forum seem to imply. This is probably more of a negative factor, in that if it is absent, it can cut down sales, but its presence doesn't actually drive sales that much.
Super fast frame rates seem to be the big thing now. Electronic shutters that can do 1/32000 second and 20 frames per second. I'm sure that will get up to 60 fps eventually, same as video, but if you aren't shooting sports, I really don't think this moves the needle much. 7 or 8 fps is plenty for me -- probably more than I need in most situations.
Even the focus on high iso performance is a bit of a distraction. It is nice to have, but I would rather have better low iso (100 to 800) performance. Better dynamic range. Good colors. Extremely low noise in the shadows. And that's where cameras like the A9 actually are a step backward. I know it isn't a landscape camera, but I just don't care much about the sort of specifications that Sony and Fuji seem to be pushing these days and I don't think I am alone there.
It is easy to get a skewed version of reality if you spend much time on the Forum. Everyone is shooting sports and needs 15 fps with fast tracking auto focus, photographers want 4K, no, 8K video, photos are being destroyed by shutter shake and the list goes on. But most folks just want good performance with straight out of camera jpegs and not to think too much about their camera at all.
