Hello, I own a Casio EX-M2 and used it constantly for 3 years. It's been a very reliable and very compact camera for me, however, lately, the lens has been getting dirty, however, I'm sure it's the dirt or dust from the inside I cannot clean. Perhaps this is because this camera doesn't have an automatic shutter protector. How do I go about cleaning the lens from the inside? I don't think I have the warranty anymore. All my pictures now have a black dot on the lower left hand corner. I've attached a picture.
As you can see in the picture of my floor, there's a black mark on the lower left hand side I want to get rid of. Should I take it to a camera repair shop? How much would they charge? Any advice appreciated.
