It doesn't depend on the camera, it depends on the lens.

The answer was always the same. Some lenses for 35 mm SLRs give better results with more extension, others with a diopter in front. The only way to find out which is better for the lens in hand is to try both.
Back then I had a 50/1.4 Nikkor, didn't know much, had little money. So I bought a couple of Nikon's single-element diopters and tried 'em. The results were so terrible that I accumulated my small monetary units until I had enough to buy a 55/3.5 MicroNikkor and got one. Within a year I'd stopped using the 50/1.4.
Several posts here have recommended getting a macro lens. That's the right answer, especially at today's prices for used macro lenses.
