Take one professional photographer, the cheapest camera available, and watch him go! On this video, fine art photographer Harold de Puymorin takes a crappy point and shoot camera and makes stunning images.
This goes to show that it’s not the gear you own that will make you produce good images. It may help, but it’s not essential. It’s your creative use of the tools you have available.
Some of the best portraits I’ve done were captured with a 100$ 50mm 1.8 lens.
So, embrace your constraints, don’t let them detain you, and go make art.
