I do not know where the idea originated that it was bad to use more than one camera in a lifetime. I do not know how such a stupid question is not a question. You tell me. How immoral is it to use a variety of cameras. I am using GoPro. Why. Because it’s a serious camera, and no one is using it in Fine Art Photography because the values of the mainstream culture stem from 19th Century realism in painting, and if that was not the milieu you worked in, you are not really an artist, and what you did had nothing to do with art. The audience will chop your legs off at any given moment. I make my art anyway, and frankly, I don’t give a flying fuck what anyone thinks.
