Photographers asked to cover events:
60's - 90's: "Sure, I have a nifty 50 and some rolls of 400"
2017: "Oh my, I don't know! My 4 high end cameras do show some light noise at
ISO 6400 and one of my 10 lenses is max F4
"
Here's a useful site if you have been using Flickr for a while, input your Flickr username and it'll scan all you images and give results of your most used settings. If you rarely go above ISO 1600, and tend to favour mid range focal lengths, and don't tend to crop images much, then Full frame might not be so necessary for you.
