peter_smirnoff Posted February 3, 2004 Share Posted February 3, 2004 How is it possible for the new D70 dSLR to have mind-blowing 1/500 flash sync speed and 1/8000 shutter? This is better than most SLRs, let alone the presumably superior D100... Have they introduced a new shutter mechanism?Thanks Link to comment Share on other sites More sharing options...
arnabdas Posted February 3, 2004 Share Posted February 3, 2004 I do not think they have introduced a new electro-mechanical shutter mechanism as common to other electronic AF cameras. Shutter and sync-speed in DSLRs can be further "capablized" by tweaking the CCD capture times and I guess that's what they have done -- Link to comment Share on other sites More sharing options...
Jerry_ Posted February 4, 2004 Share Posted February 4, 2004 The F5 body can 'sync' at 1/300th, or generally at 1/250th. It, too, has a 1/8000th top shutter speed. As new digital bodies are released, the older models seem less than modern, but that is the way marketing folks want you to think. The D70 also requires a (new generation) type of Nikon speedlight to be fully functional as engineered. Link to comment Share on other sites More sharing options...

ci_p Posted February 4, 2004 Share Posted February 4, 2004 As regards the 1/500 flash sync speed, a smaller sensor would allow higher sync than a larger one, even with the same shutter, I think. Link to comment Share on other sites More sharing options...
peter_smirnoff Posted February 4, 2004 Author Share Posted February 4, 2004 You're miising the point. Why does the D70's with its *smaller* sensor have a MUCH faster shutter than D100, 10D etc??? Link to comment Share on other sites More sharing options...
AntonioC Posted February 4, 2004 Share Posted February 4, 2004 Because it uses an elecronic shutter, beyond the mechanical one, as a poster already suggested.Basically, it powers the CCD for shorter intervals than the mechanical synchro (while the shutter is open).Brilliant!

spencer_hahn Posted February 4, 2004 Share Posted February 4, 2004 But what about the 1/60th internal flash sync? That's terrible! If I had to guess why they did it I'd say maybe because the flash is really weak and they need an extended pulse, but 17ms?!?! Wasn't there another camera recently that had the same limitation (I think maybe the N55)? Link to comment Share on other sites More sharing options...
2069 Posted February 5, 2004 Share Posted February 5, 2004 Is it true that the flash sync is 1/60 for the internal flash...i thought it too was 1/500.... anurag Link to comment Share on other sites More sharing options...
joseph_wisniewski Posted February 5, 2004 Share Posted February 5, 2004 Someone posted a letter from Nikon on dpReview. The D70 syncs at 1/500 sec for either internal or external flash. The 1/60 number is the lowest shutter speed it will select in aperture priority or programming modes before it insists on using flash. Link to comment Share on other sites More sharing options...
david_gonzalez Posted February 5, 2004 Share Posted February 5, 2004 That's how the original Canon 1D (CCD, not CMOS) did it, by energizing the chip. It had(has) a 1/500 sync with a 1/16,000 top shutter speed. The 1DMarkII with it's CMOS is back to 1/250 and 1/8000. Apparently CMOS can't react as quickly.

nino Posted March 17, 2004 Share Posted March 17, 2004 Yes the D70 has an impressive synch speed, but the fact it's not compatible with other flas uniths like my sb50-dx is appalling on Nikons part. I have discovered that the Sb50DX speedlight does not work with the D70 body, in Auto mode. It only fires in manual mode, which is nearly useless. Might as well buy a $50 no mane flash. shame Nikon.

erick_lamontagne Posted March 17, 2004 Share Posted March 17, 2004 The D70 still use a mechanical shutter, right? If so, I think that what's impressive. As far as I know, the mechanical shutter still has to be fully open during flash. If the camera can record at 1/500 without flash, it should be able to record with flash, as long as the mechanical is fully open. I don't see what the electronic shutter has to do with it. What am I missing here? Does it have a mechanical shutter? Link to comment Share on other sites More sharing options...
