My Canon 50 mm 1.8 lens stopped focusing properly on two occasions in the heat. It gets hot here in the desert and doing and summer temps can be 100 easily. It's a dry heat. I was at my sons soccer game and when soon as it got hot the lens started malfunctioning. I even was keeping it in the shade. Once it cooled down it stated working again. Is this a common phenomenon with lenses? Thanks!
