I mentioned in my prior post about my Rokinon 800mm lens that some of the distortion in the photos was due to air quality. This is a quick post to explain what I meant by that. I live in a wonderful place on the east coast of the United States that is blessed with horrible air quality. The humidity here is almost other-worldly at times. For most people out there, dealing with the Optical challenges of humidity is not something one ever has to deal with. However here in Maryland, if you’re shooting over distances it is something you will have to deal with. Yesterday I took a quick video that displays this problem. There is some initial shake of the camera from me starting the recording, but once it settles, you’ll see ‘waves’ seem to wash over the image, that’s humidity at work my friends.

That’s how bad it is on a temperate day with the humidity in the low 20%. During the summer doing the same type of test would be far more exaggerated. If I’m able to stand it and dont mind subjecting my camera gear to that kind of brutality, I’ll try to do the same test again during the summer on one of our 90% humidity days.
