Heat distortion.

Yes, Greg, I can't use my 500L much most of the year for landscapes because of heat distortion. It is okay for closer subjects. When it is all said and done I was still surprised in a negative way at what the A7R delivered. Now that I have seen the mess I will return determined to get some clear cables. It has become a project for me because it is obviously a challenge for digital cameras to resolve. I will pick a cooler day and perhaps around noon when there are fewer shadows. I will use longer focal lengths as well. Should be interesting.
