My newest 2nd hand camera let me down after 3 months. Nikon F4S.
Shutterproblems: half frame underexposure or full underexposure.

Could it be that buying progear leads to more chance on encountering worn out mechanics, suspectible electronics?
My thoughts were: let's buy a pro camera, it got more gimmicks(MLU,..), it's more durable so would be less risk.
Now I'm back on the other side: buy a medium specced thingy, less gimmicks but also mostly less used and still in better shape.
