One HUGE reason for loving m4/3 camera systems!!!

I'm definitely not a pro photographer.

But I do work in a line of business where the technology evolves fast, there is always pressure from the "latest and greatest" and the new kit gets all the press and glory.

I work with a piece of crap old machine that I will use til it is utterly unable to earn me any more money - then I will switch to the next cheapest thing which lets me carry on in the same way without learning a whole load of new stuff.

Often amateurs in my field have (much) better kit than me. I say "bring it on" and invariably produce better results than them because this is what I do all day every day for my living.

I'm motivated by feeding my kids - not getting the best new things to play with for myself.

I simply dont see why professionals in any field would behave any differently.

Amateurs worry about kit - professionals worry about money.
