YES!My belief is that my understanding of equipment (and purchases, to a limited extent) have made me a better photographer. The art is never fully separate from the technique, the technique almost always aligned with the technical.
Of course, many people have created amazing work on the cheapest gear. But how would you know what really suits you without trying both the best and worst?
And once you have a reasonable range of experience, consider the possibilities that (a) you'll make better pictures with equipment you like and (b) that if you never find equipment that gives you better pics (note: better, not good in absolute terms) it may not be the equipment that's holding you back.
