My D70 suffered the "Blinking green light" symptom back in mid June which is 2 months+ past the waranty and Nikon HK repaired it for free and they also adjusted the slight back-focus problem. Most of the D70's sold back in April to Sep 2004 can potentially suffer this problem and I'm glad Nikon publicly acknowledged such problem and also offering free repair. If you or your friend own one of these and even if the D70 has not exibited such problem I still suggest to take it back to Nikon and have them replaced the electronic components and also ask them to check the focusing. Despite this slight inconvenience the D70 remains a very nice and versatile machine that can generate fantastic images given the right lens and skills.
