As bad as it sounds, yes... But there is a catch.
You still need the know-how to really make use of what you buy... Basically, not buying the most expensive stuff and being clueless to how to use it properly.
As my lenses and body got better via upgrades, my images did as well. Having better high ISO, sharper/faster lenses, more specialized lenses for dramatic effects, etc... But my knowledge grew just as quickly as my gear.
My Samyang 14mm is one example, although its quite cheap at around $300... Some of my best images came from that lens simply because it was a 14mm on FF. I could not pull off those images with any other lenses. Now without the Samyang I would be stuck buying the $2000+ 14L... So sometimes you get "stuck" buying expensive items because there simply is nothing cheaper.
Much like anything, the knowledge is backward compatible. You can give me a T1i and 18-55 and I am sure I would be able to do great things with it... But I would be very limited compared to what I own (5D3, 70-200 II, 35L, 24-105L, etc...). Much like throwing a professional race-car driver into a basic Toyota Yaris. The talents basically get wasted because the equipment does not match to potential. This really is a summary of my whole post! Wasting talents without proper tools.
So in a way, you NEED the knowledge to make the best use out of your expensive gear. Usually this happens naturally... I started with advanced point and shoots when I started to learn manual controls... Moved up to a XSI and then the T1i... Once I outgrew those I was with the 7D, then 5D and 5D2 and now the 5D3. I evolved with my gear. The more I learned, the more money I had invested in very expensive gear. So I know generally how to make the most out of what I own and how to achieve exactly what I want with what I have. You will see me changing lenses like crazy because its mandatory to get the image that I vision. It drives me nuts to keep one lens on for a long period of time because they all do something very different.
Hope this makes sense!
