Diopters and "apparent focusing distance"
Like many people in middle and and beyond, I have difficulty focusing
with my eye's lens. Basically, my eyeglasses do the focusing. With my street glasses, infinity is sharp; closer than about 20 feet, it gets fuzzy. Cameras often display the image as if it were about 40 inches away. For folks like me, that's not good. I have film cameras that have add-on or adjustable diopters. But what about point-and-shoot digital cameras? I want one---not an SLR but a truly pocketable camera, and I'm looking for good image quality. But when I have looked through the viewfinders (friends' Canon and Kodak models), it isn't good. Does anyone know the scoop? Am I going to be reduced to trying to look at the LCD on that back through the small lenses at the bottom of my bifocals? |

A reasonable number of point&shoots have viewfinders with adjustable diopter correction. It seems to be most common on the larger (and more expensive) models; I don't know if anything small enough to be called pocketable has one. -dms |

I've got the same problem, but it isn't actually all that bad because you don't REALLY have to see whether the subject is in focus or not. With the Camera on "Auto", it WILL be in focus if the camera gives you the OK signal. With manual focus, it's a different story. But I rarely use manual focus. Nevertheless, I moved up to a Panasonic FZ15 which has a very effective diopter correction on its EVF viewer. BTW, Panny's FZ series are killer cameras and are REALLY great values. Bob Williams |

Every point and shoot I've looked at that has a viewfinder has a diopter adjustment on the viewfinder. The DSLRs the same, however some also allow auxiliary lenses to be installed. But if it's one of the thin designs that doesn't make a pocket bulge they often don't have viewfinders at all, you're expected to use the LCD. -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |
