Every now and again we set out for several weeks, driving all the way, and stopping at various places to visit family, friends, and see the sights. This year is a tour of scenic places, and places with character. Because I want to take some good pictures, I have been going through my lenses and checking them for accuracy in focus. Of course, some lenses are better than others, and some systems work better than others.
The Nikon D7000 has the ability to adjust the autofocus in different lenses, and store those manual adjustments in the menu, for up to twelve different lenses. I have been going through all my autofocus lenses, rather painstakingly, to sort them out. Only one is really out of kilter, and it could be that I just need to send it in to be refurbished by the manufacturer to factory specifications. Needless to say, it will not be traveling with me!
There are a lot of ways to check the focus of a lens, so I won’t get into it here. The final test, though, is on the eyes of my victim. His left eye is the one I use – don’t ask why, I don’t know! Once I like what I see in the lens, I record it by naming the picture with the adjustment in the camera, the f/stop, and file it in a calibrations directory. I’ve heard that lenses should be checked every 6 months or so, and certainly be checked out with any new camera.
