Maxxum 7 diopter question.
I am thinking of upgrading from my old Canon A-1 to a Maxxum 7.The
specifications of the Maxxum 7 state that there is a diopter adjustment of -2.5 to +0.5. (It also seems to be fact that the viewfinder in any 35mm camera itself presents a -1 diopter shift.) I am farsighted so to see objects close up, I need to wear +2.0 diopter corrective lenses. My question is, when you look through the viewfinder, at what distance is the image presented? In other words, if you were able to place the lens of a second camera into the viewfinder of the Maxxum 7 (the first camera), at what distance would you need to focus the lens? The closer the image is displayed to my eye, as well as the image data in the viewfinder, the higher my diopter correction needs to be. Searching through past threads, some people say that the image in the viewfinder is equivalent to looking at the subject from a distance of one meter. But I cannot find any evidence from the manufacturers of any camera to confirm this. Also, if I use the adjustable diopter wheel on the camera, how can one calculate if it falls within the range of one's eyesight? I have contacted Minolta and while they complimented me on the thoughtfulness of my question, they did not have an answer. Thanks for your reply, David Farber L.A., CA |

I have contacted Minolta and while they complimented me on the thoughtfulness of my question, they did not have an answer. Not sure about the 1 meter apparent focus, however, the viewfinder info is always in focus (if your eyesight or prescription is correct or the diopter setting is correct for you). NOTE: According to the Max 7 spec (KM site), the diopter adjustment is -2.5 to +0.5. (not +1.0). If your correction requirement is +2 you can order that diopter as a "clip on" device for the viewfinder. This should give you a full view of the scene and the displayed data in the viewfinder. eg: http://www.bhphotovideo.com/bnh/cont...u=35587&is=REG Sorry if this doesn't answer the heart of your question, but it should allow you to use the camera. The clip on would be best for you as you could visualize your scene out of the viewfinder normally and then have the corrected view when looking through. No need to fumble with glasses. You could also ask this question at http://groups.yahoo.com/group/Minolta/ where there is more likely to be someone with the same problem and same camera and can answer with all the details.

meter. Then I would also be able to read the display screen on back of the camera without having to change or remove glasses. Of course, this is all dependent on the viewfinder image being projected at one meter. David, I would suggest that you locate a Maxxum 7 in your area and try one out before buying. Nothing like having it in your hands (or in your case, having your eye in the viewfinder) to know how it will look to your eyes).
