Newer tech mainly makes things easier
Portrait, weddings, wildlife with the recent mirrorless eye detect tracking etc must make things not just easier, but also take a lot of pressure off of getting 'in focus' shots, etc - That's not to say there still isn't a lot of skill & knowledge & experience required mind you...
I still wouldn't fancy it even with the latest gear!
But on the flip side, an hour out could result in an awful lot of 20fps images to sort through - I wouldn't fancy that either!
I shoot mainly landscapes, night skies, woodlands so my 2013 A7 works just fine!
