It seems I’ve run into a problem with the 100–400mm lens that I purchased this past June. The image in the viewfinder began jumping around when I pressed the shutter button half-way—often this would continue even after shutter release. I contacted Canon’s customer service. Based on my description of the problem they suspected the image stabilization had failed. I sent the lens to their service center and they accepted the lens under warranty. I hope to have it back in about another week. I’ll let you know how the process went, as well as how the lens works when I get it back into the field.

I'm a retired medical sociologist from the University of Rochester. Climate change is one of the two great challenges facing humanity (the other is nuclear weapons). In writing about the impact of climate change I read reputable books and articles on the topic. So when I make statements about climate change you will see a link taking you to the scientific source(s) of the information I provide. As for my independently published photobooks, each has gone through several layers of editing and peer review for both readability and accuracy. This is not to say that everything I say is accurate. Even the New York Times makes mistakes. So, if you find something that is factually incorrect, let me know. I hope you find reading my blog a positive experience. If you do, please encourage your family and friends to have a look. You can find photos from my other photo work by clicking on the My SmugMug Gallery tab, above.
