I love my X-T20. It’s the best camera I’ve ever bought - except for one thing: since I bought it 15 months ago I’ve had to have the sensor cleaned three times. Previously, I’ve had a LUMIX G3 and G6 and never had to get them cleaned at all. I know getting the sensor cleaned is an occupational hazard for mirrorless camera owners but I don’t use this camera any more than those, so have I just been unlucky or is there something about the design of the X-T20 that makes it particularly vulnerable to dust and dirt?
