Wow I envy you, really I am, my want/wish list is so long I cant see the end of it
You can buy the best camera on the market (if you can figure out what it is) and every lens that Nikon or Canon makes. You can buy every bell, whistle, doo-dad, and trinket that
B&H and
Adorama sell. The only difference between that and now is that you'll have a lot less money and a sore back from hauling all of it around. You won't be able to take better photographs because the two things that makes one photographer better than the next are free. Those are Knowledge and Experience.
This is true. If you think that your pictures will automatically get better with new gear, then clearly the blame for bad pictures is being misplaced.
On the other hand, you can also gain enough knowledge and experience to have established what kinds of pictures you like to take and you've realized the limitations of your current gear. Maybe different cameras or doo-dads will be more suited to your shooting style. Maybe you'd like to expand to different sorts of pictures that your cameras aren't very good at. Or, it's an accessory that will help you make more use of your current gear. If I, for example, decide I'd really like to focus on landscape, I'll understand that some of my cameras will be better at that sort of picture than other cameras. I might also invest in a different lens that will capture landscapes better, or some new filters for my current lenses.
But I agree - I've never understood lusting over gear for its own sake. Not saying that goodguy is guilty of this, just that I don't understand it in general.
