You might also want to get a set of extension rings so you can push the macro scale a bit further for higher magnification close ups. A ringflash is an optional extra but they are expensive. Handy if you need to do a lot of close up macro work without worrying about lighting. Otherwise a north facing window and a steady hand will do it. Regards, Martin Brown

Called a copy stand (or big ones, 'copy camera'); used for things like microfilming newsprint. Have you tried putting your mainly-flat items onto a flatbed scanner? Some scanners have really good depth of field. High end copy cameras are going for pennies on the used market, because digital imaging has got so adept at working around the keystone/distortion issues of careless camera aiming.

The young man linked it with about two dozen friends in a neighbourhood gaming LAN. He'd had his new computer for only two days when lightning struck a nearby house, partially vaporising a disused TV antenna. The young man was out and the computer wasn't even turned on. The +5V rail was shorted to ground. I couldn't provide warranty for a lightning strike, so I replaced the mobo at cost. Some 2 years later, I had an inspiration. I downloaded the datasheet of the LAN chip and identified the supply pin. I desoldered the pin and the short disappeared. I happened to have a spare Athlon XP CPU from a previous upgrade, put that in and powered up the motherboard. Lo and behold, it worked perfectly. I fitted a discrete LAN card, HDD, monitor, etc - all spare used parts accumulated over the years, mostly discarded by customers from upgrades. The result was a complete computer for zero cost. My daughter is still using it and she says that she has no need for a faster machine.
