I've often wondered if people always get G.A.S or are always looking for the next camera that can focus a millisecond faster,lock on and track more reliably, has a larger sensor, more megapixels, better high ISO/low noise etc etc...........
Or are you content with the gear you have? Does it meet all your needs and do all you want?
As for myself I'm actually content right now, my camera bodies & lenses do all I want and I have no purchases planned.
I find it rather pointless because people often forgot that it is their own performance they should be thinking about.
What is the point of buying a new camera that focus a millisecond faster than the camera belonging to the photographer standing next to you, if the guy with faster camera was slow to react to something, while the other guy foresaw something and already started taking photos? Your new camera may have a shutter lag of like 50ms while the other guy's camera may have a slower lag like 100ms, but you moved your finger slower than him, thus despite having a slower camera, the other guy took a photograph before you do.
I once had a computer with Windows XP and still using Microsoft Word 97, a friend pointed out that Windows 8 and Office 2010 would be a lot faster. I feel like wanting to say "Huh!" Because I was trained in touch typing and could do about 50 words per minute (I forgotten my speed) but I know my friend would jab at the keyboard with index fingers thus is slower at typing. I may have a slow machine and software but I could finish a one page document before the guy with the faster machine and software.
I would prefer to wait until the technical gap is a lot bigger. For example, if I have a camera that have 5MP and out comes cameras that have 6MP, I would not bother upgrading. But if I have a camera that have 5MP and out comes cameras with 20MP, I would buy. If I have a camera that have a maximum of ISO 800 and out comes cameras with ISO 1600, well I may not think about it. But If I have ISO 800 and out comes a camera with ISO 6400, I would.
I would not bother drooling over the next model if it have an extra half frame per second than the current model. But ten years later, I would drool over a model that is generations ahead to the current model, and is like ten times faster than what I have.
