The reason to want any particular camera or lens or whatever is to get the thing that does what you want it do, the way you want it to do it. They're tools. They do things in a certain way. Very precise instruments can do what you want with a greater level of precision, if that's what matters to you. So, in a sense, the right thing can accomplish your work the right way - but that may or may not mean spending a ton of money for the "best" thing. If a Holga does it, then the Holga is the right thing.
