Having added an "Type E" screen to all of my cameras that have such an option, as well as using the original "B" screen, I got wondering if other screens would also be helpful. Does anyone here recommend other screens worthy of adding to cameras? An F3 will soon by added to my collection of FM3a, F4, and F5. If there is a good reason, I will add screens to any/all of these bodies. Landscape, wildlife, nature, travel, sports, architecture, and macro (micro) are my areas of interest in photography. Thank you for your suggestions.
