The laws of physics can be got around with technology. THats my point. Goolge full frame mirrorless and medium format mirrorless it will be around in the next few months to one years, its already happening. as will large full frame mirrorless. its just around the corner.
Trying not to come across as arrogant.
There are pages on the Internet that tell me man never landed on the moon. It doesn't make it true.
Technology will always improve but you have to understand the way that light travels (in straight lines) and the limitations that puts on the size of equipment required to do certain things.
A modern APSC CSC is a marvel to behold, is really pocketable with a pancake lens, but can't get over the size of the 100-400 a wildlife photographer will fit. Now it stops being pocketable. Do you really believe that a 400mm 5.6 lens can be made pocketable?
If you do you really have let your imagination go too far. Here's a clue, get out a tape measure and see what 400mm looks like. Using mirrors will shorten a lens but adds strange optical properties and steals light. The light stealing is less important nowadays due to better sensor technology.
But back to all things being equal, whilst sensor technology is making smaller cameras better, it's also making larger cameras better.
Simple Physics. You can't change the way that light works with technology, you can only make the hardware handle it more efficiently. But those efficiencies scale.
I've got nothing against mirror less cameras in principle, except I want a viewfinder as good as a good optical one. Technology will eventually give me one of those, but a FF or MF camera will still be bigger than an APSC camera with the same generation of technology. And a phone or compact size sensor will never give me the optical properties of a larger sensor. That's Physics too. They're good, they're getting better, but they can't kid the light they're larger.
If you can't get your head round that, I suggest you stop reading the rumour sites and read up on how the cameras we have now collect light and focus it. How bigger film / sensors differ from smaller ones. How focal length and subject distance create DoF and why comparative focal lengths lead you down an alley when it comes to that understanding.
All physics. Im not a Luddite. I've been playing with high tech stuff all my life, and all devices are built around the limits imposed by laws of physics.
