What I said in the book years ago is likely true. I do believe most photographers probably prefer aperture-priority (perhaps as they do today), and so did Barbar back then. I tried it years ago when I first went to digital in 2003, but the problems it created were so serious I soon abandoned it. And I have rarely used it for any reason since. Prior to 2003, I only used manual with film, so I did not find out how often light in the viewfinder caused underexposure. I avoided that problem accidently by just using manual exposure with film, but digital made the pitfalls readily evident. So back to manual, especially for landscapes for many reasons. If you don't think you have a light through the viewfinder problem with your system, try this test. Put the camera on any auto mode and a polarizer over the lens. Point the camera at a dark area in the shade, but arrange the camera so sun can shine into the uncovered viewfinder. Look at the auto exposure that is set by the camera. Now cover the viewfinder with your hand or close the curtain. If there is a difference, that is the problem. If the unblocked viewfinder says 1/8 second at f/16, and the covered viewfinder says 1/30 at f/16, that means the image will be seriously too dark with auto exposure due to ambient passing into the viewfinder.

I'm lost. What has light in the viewfinder and the problems it caused you to do with using aperture-priority exposure? And how does manual exposure then solve your problem by preventing light from entering the viewfinder?
