Q1) XQD is some kind of trick. The video bitrate of new cameras is not high. XQD cards are pure commercial move now.
Q2) The problem is another - Pentax cameras is far from high limits of SDHC and SDXC card...
))
Q1) no it is not.
latest definition of the XQD standard is featuring support for
PCI Express 3.0 with transfer rates up to 8 Gbit/s (1000 MB/s)
Furthermore: the cards are way more rugged and less failure(they can never develop the heat concentration of an SD-card.) prone from a technical point of view. no way around that. thats a fact.
... etc.
Q2) That is a problem and PENTAX would do good to care about that issue. otherwise our beloved system may go extinct pretty soon.
If Reps at Ricoh-Imaging have a rest of sanity left, they would do good to care about getting a faster camera on the market...
... Despite, the baseless fears about compatibility can be rendered obsolete when a Dual-Multi-Slot (1 SD, 1 CFE/XQD)is installed in a camera...
(you can always pop in an SD-Card... keeping in mind that you favor SD-Cards, you dont care about security anyway so you should be good with one SD-card mounted in your camera. other will love to install an XQD or CFExpresscard in the second slot and enjoy faster write speeds.)
... I wouldnt worry about the costs of XQD cards either... Since a real tough, "not so failure prone" and "hard to brake" SD-Card will cost you the same or more than an XQD card...(which is by design less likely to fail)
And no, no one NEEDS memory cards that fast. but we dont live in a communistic state(at least i hope so for you), so i feel pretty lucky people dont decide over other people what may be the cheapest and lowest standard everyone NEEDS or is ALLOWED to have. THX.
------though i think, the advantages of faster memory are obvious, and its only logic, that the other hardware should also be fast enough to utilize the full possible write speed --- I wanna jot down shortly ONE reason, why i think, that could make sense for us.
the upside of having real fast write speeds: if the cameras circuits(CPUs+Board) and bus speeds are also top notch... you would NOT need expensive buffer memory that big in your camery any more.
that could cut costs for a cameras production in a win-win way.
admitted: I really dont know the prices for really stable and 100%error-free superfast buffer memory, but i guess its not cheap either, otherwise our cameras would be able to pull more pics to the buffer before the K-1 slows down ... for instance.
