Originally posted by Lowell Goudge even if pentax release a new flash, why would they go back and update cameras. Unless the flash is significantly shorter in duration, such that they can offer full sync speed on trailing edge trigger, as opposed to 1/2 full sync speed, I can't see it.
Maybe the K7 if the maximum opening time of the shutter is OK for 1/250th but the AF540FGZ is just too long a duration (possibility since it now overlaps a little the K10D shutter at full power) or if they could offer 1/250 at marginal power only, again assuming the shutter is open long enough
They
might decide to update very recent cameras, such as the K-7, because such recent buyers might be considered a market for the new flash, but not for a new camera. I don't think that, despite a lot of postings here, many Pentax owners buy every new body that comes along. How many own, or have owned, an *istD, a K10D, a K20D, a K-7 and are planning on buying a K-5? A few, but not many.
Pentax has to be aware that K-7 owners would be a potential market for a new flash (or even a new lens) that required new firmware.
OTOH, they might decide that those who wish to buy the new flash must first buy a new camera. Their marketing/accounting suits would have to decide which course of action would generate more revenue.
I'm not saying that they definitely would provide such a firmware update: just that there is a business case for it, that is missing or less important for camera feature updates. If they add support for a new flash, they might sell a few more flashes. If the add support for a new camera feature, they might sell fewer new cameras. Which one has a snowball's chance in h*** of happening?
Personally, I think that significant future updates are very unlikely.
