Re: D70 lowest iso 200

If you are comparing the D70 1/500 flash sync to the D7D you have to remember that the D70's lowest iso is 200 ISO this is one stop higher than the D7D which means in the same lighting situation if you were shooting with the D70 you might have 200 ISO F5.6 1/500 sec where as the D7D would be 100 ISO f6.1 1/160 sec this is only half a stop difference . I can live with that.

I was thinking about this the other day, re: the faster synch of cameras like the Nikon D1 series, Nikon D70, and Canon EOS 1D.

This is something that Nikon and Canon did where there were able to implement an on-sensor electronic shutter that was faster than the mechanical shutter, so, in reality, they could actually do even faster than 1/500th synch. However, when they moved to 10MP CCDs, this wasn't possible anymore, and newer cameras lost this feature. Someone on the digital photography technology forum thought it was probably because the older CCDs stored data between rows in the sensor, trading off vertical resolution for on-sensor buffer.

The Nikon D70 had a 6MP Sony CCD. The KM 7D had a 6MP Sony CCD. The KM7D was released after the D70 (and well after the D1 and 1D). I wonder why KonicaMinolta didn't implement a similar electronic shutter to what was used in these other cameras.
