I forgot that I had left my 5d3 and L lens in my car's trunk for a couple days while the sun was out and the temps were in the 90's. When I opened the trunk, it felt like hot, but not like "inside the car" hot because obviously the trunk is dark.
I tried to simulate the scenario with a thermometer and it said 110. I know that one of the days was close to 100 degrees and sunny, so I'm thinking it might have been 120 or 130 at some point.
I've used the camera since, and the images and performance appear normal. The manual just says avoid high heat....I'm not sure if 125 qualifies as high heat. I know when I lived in the desert for a few years that it's sometime 115 degrees and sunny, which might subject your camera/lens to 130 degrees or more.
Has anybody ever done this? Do I have anything to worry about?
What about the lens, can a lens handle this type of heat?
