But the capabilities of a 17 year old DSLR would not compare to a modern micro43 camera. And the OMD EM10 mk2 is sooooo much smaller and easier to carry around.
And?
I will have just as much fun with my 17 year old dinosaur as you will with yiur new mirrorless olympus. Unless you're a pro or a perfectionist the age of the tool doesn't matter.
I've built guitars with 100 year old jointer planes that I enjoy just as much as modern guitars built with 1 year old cnc machines, and a 150 year old cast iron dutch oven can make a mighty tasty cake.
Put less faith in the tool than you do in the craftsman, and you will do just fine.
