Give a cheap violin to a violin master and they will still make beautiful sounds with it. Give a Stradivarious to a begginer and the reverse will happen. It's not the camera but the photographer's skill and talent...
I see so many invested photographers these days with all the pro kit and not a clue how to use it.
Give a cheap violin to a Anne Sophie Mutter and she will still sound good.... but definitely not as fabulous and something will be missing a bit for sure.
If you were to steal a top violin player's instrument they would probably literally cry and then go all Taken on you: "I don't know who you are. I don't know what you want. If you are looking for ransom, I can tell you I don't have money. But what I do have are a very particular set of skills; skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let my Strad go now, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will...."
And there is a reason they would be like that.
Give a Strad or Guarn to a beginner and he might still not be terribly good but unless he is really, really poor or like in the first few weeks his tone may be a little better and if he is a skilled beginner he will sound noticeably better although he's not going to be able to sudden do anything a master can. I've personally tried crummy and excellent and I definitely sounded better with the top instrument, that said of course I didn't transform into Perlman.
For cameras give a sports pro a rebel and 70-300 IS and his take will instantly go considerable down.
Give a beginner a 1DX+ 300 2.8 and his take will instantly go up a good deal.
But the pro will still have the better overall take (unless he is a really crummy one and the beginner has mad talent).
