Re: not odd at all
In reply to David314, 8 months ago

why is that odd?

expeed 3 can obviously proces DX crop in the D800 at 9 fps,

again, i think the limitation is getting the data converted in 14 bits AND keeping the read/thermal noise low

I wonder why Nikon didn't let the D800 go to at least 8 fps in DX mode, let me repeat DX mode, at 12 bits

i do NOT expect any firmware upgrade from Nikon,

With the current strategy from Nikon, one might was well wish for a flying pony because that is more likely to happen than a real performance firmware upgrade.

if it is a data transfer from the chip issue,  it would depend on the databus width: it might be 8 bits and take 2 reads. If that were the case it might be able to read twice as fast by just taking the first 8 and dropping the 2nd:  like a low res version.

But, seeing as the D300 slows down considerably from 12 bit to 14 bit, i suspect D300 is a 12 bit bus and you would expect the D800 would be the same or maybe 14 bit.

If that is the case it would be very difficult to get performance gains on the transfer short of overclocking it. probably not a good idea on a dedicated piece of hardware!
