I've not seen the article but in practice my DSLRs have been fine when I use the readings from my Minolta Spotmeter F, no ISO correction needed (mainly used for metering with studio flash). In addition when using my DSLR alongside va film camera the reading are comparable. That doesn't mean all makes etc will be similar, in the end it's about knowing your equipment.
