My evergreen Olympus E-1 is now twelve and a half years old; I've been using it since 2008. It is my favorite DSLR.
I've had the Olympus E-M1 since 2013. It proves its capability, versatility, and quality to me every time I use it. And it's gotten better and better as the firmware has been improved.
The Leica X typ 113 was a surprise and a delight when I got it last Fall, 2014. In some ways, it's the best "grab and carry a camera, take pictures" camera I've owned. It instantly gets out of my way and let's me see through it.
The Leica M-P typ 240 I acquired this Winter of 2015 is everything I'd hoped the M9 would be. It finally achieves the transparency and fluid use of my film Ms. So glad I went for it.
That's as done as I want to be with these tools, for the near future. Much of the rest will go, other than sentimental artifacts driven by nostalgia.
