Thanks for the info. I'll keep it in mind. My miniature bench vise can hold
the glass steady. My Sony has a built-in zoom feature that works pretty well. The auto-focus works OK, but works better with a little background light. The savings in film and developing costs is a true breakthrough for an amateur casual photographer like me who needs to do everything at least a dozen times and likes to see the immediate results. Bill W0IYH, Life Member IEEE wrote in message ups.com... From: "William E. Sabin" on Fri 26 Aug 2005 14:09 I have a new Sony digital camera 7.2 megapixel that I have been slowly learning how to use. I shoot pix using a tripod and max megapixel (20 megabytes), then I use a program that creates an optimum JPEG file that QRZ.com prefers that is a little less than 500 kilobytes. I use an external diffused flash that works quite well, attached to the Sony. I can shoot a dozen pix and delete all but the one I want (at no cost for film and developing). Having controlled my "megapixel jealousy," let me suggest a very easy field-expedient extreme close-up adapter: An ordinary large magnifying glass. :-) With an LCD screen now the optical viewfinder replacement on cameras, a magnifying glass held in front of the lens can be positioned easily for focus, even with the auto-focus varieties. It can get in there very close for detail shots of the ever- shrinking size of modern electronic components. I've used a 4" diameter office type of magnifier glass with great successs on close-ups using a Panasonic auto-focus digital camera, magnifier held in the hand. |

Thanks for the info. I'll keep it in mind. My miniature bench vise can hold the glass steady. Unless you do time-exposures (rare), it is possible to hand-hold the magnifier without blurring or distortion. The LCD is better than the 35mm SLR through-the-lens viewfinder in my opinion. My Sony has a built-in zoom feature that works pretty well. The auto-focus works OK, but works better with a little background light. Most seem to be like that...more light the better. I've used a 20 W halogen-bulb mini desk light from the IKEA store for good Illumination on small subjects. According to the old Norwood photo meter it has the same output as a 150 W incandescent flood at 2 feet. ["over 150 W CW above 300 GHz" - :-) ] The savings in film and developing costs is a true breakthrough for an amateur casual photographer like me who needs to do everything at least a dozen times and likes to see the immediate results. As one who got into "serious" amateur photography in high school (Class of '51), 35mm route, I have to say it's *FANTASTIC*! :-) Wife and I got a Panasonic that holds all images on a 3 1/2" floppy "Super Disk" (over 500 MB) back in 2000. A couple years ago I started to "take notes" on various projects with that camera, find it is ideal to show progress, even to show oscilloscope screen waveforms (tripod or other stable mounting recommended, plus a large cover cloth to cut out background reflections). That Panasonic model went off the market but it continues to work fine. A new Aiptek still/motion-picture we just got cost only a third of the Panasonic's price; I'm still getting acquainted with it only two weeks out of the box. Smaller, lighter, it has a manually-selectable short-range focus capability. The tripod we use with it (in place of cheap supplied mini-tripod) was bought by me in NYC in 1952 for use with a Kodak Retina II 35mm range- finder camera.
