In the first place, I contribute photographs to Commons.
I prefer to use Olympus gear over the widespread N… and C… brands, mainly for the much better lenses Olympus makes (at comparable prices). Having started with the E-500 DSLR and advanced to the E-620 and E-5, I switched happily to the wonderful mirrorless, tiny OM-D E-M5 Micro Four Thirds system in 2013, rounding the set out later with the phenomenal E-M1 as soon as it finally got shipped into my direction.
I sold nearly all of my zoom lenses and use primes mostly, for their bigger aperture and altogether better image quality. The only zoom lens I use with Micro Four Thirds is the outstanding M.Zuiko 12–40 f/2.8 Pro.
In case a small beltpack camera was needed, I used to have an Olympus XZ-1, which takes quite fine images considering its size.
Images are mostly re-developed from RAW files using the RawTherapee software.
Oh yes, this is a microsoft-and-apple-free desktop, I use Kubuntu on a Lenovo Thinkpad, to which, for image editing, an HP LP2465 monitor is hooked.
