A good move whatever the motives. Some people rely way too much on manipulation. If you spend hours in front of a screen with working on your files what does that say about your ability as a photographer?
I was an Oly OM shooter before going digital. Small, light camera and lenses. Easier for backpacking/climbing, without sacrificing quality. In keeping with the size and weight benefits of mirrorless over DSLR, I've collected a bevy of Oly primes on Ebay- generally paying about 1/10 of the original price. I got the 500mm f8 Reflex, 300mm f4.5, 200mm f4, 135mm f3.5, 50mm f1.8, 35mm f2.8, and 28mm f2.8 for about $700 total. All but one are in mint cosmetic and mechanical shape- the last is excellent mechanically. Sometimes I use Piccure to snap-up a shot, often not. These were taken with my X-T1, using the 500mm f7, and run through Piccure.
These are boring, test shots, and are only meant to convey the IQ available from the old Olys.
Enjoy!
PS I use $15 Chinese/Ebay adapters, and don't think they sacrifice sharpness.
