A camera is to a photographer like a cutting tool is to a machinist. While it's true that using a high end digital medium format camera to make technically and artistically poorly crafted images is as pointless as using a 6-axis mill to make an L-bracket, a high end camera isn't the photographic equivalent of that mill. It's just the cutting tool. The equivalent of doing that would be using a huge studio with all the lighting capabilities you could ask for, to take a very simply lit picture of some object that would look the same way if you just used a mini tent. Or to take portraits with the built-in flash against a white wall instead of making use of the backdrops. Like a 6-axis mill, a full studio has the potential to let you create things you couldn't before. A high end camera is more like an advanced cutting tool. It does the same thing as more modest ones, but the finish can be a bit better if you know what you're doing and it can handle some specific situations better, while being more cumbersome when doing almost anything else. But a lathe with a insert tool or a lathe with an HSS tool is essentially the same thing. You can make a screw with both. Allen Millyard does even his own carburettors. Don't expect to be able to make a carb because you bought a ceramic cutting tool. Get a welder instead, the lathe alone can't do it. It's not the brand of tools an artist uses that makes their work what it is, it's the way they use them. This doesn't only go for cameras but every piece of kit as well. Don't focus on getting the same Mole Richardson units your idol uses, find why they use them and then see what you really need. Don't lose your sleep about what specific lens model they use either, the impact is minuscule unless it's a very quirky lens. There's no use in having fancy gear if you can't pose, light or dress your model properly or if you don't understand the importance of the surroundings. I'm using fashion as an example but this goes for every genre.
