IMO Auto modes - especially programmet AE - never worked well with Pentax cameras and a flash. The camera will just set the shutter speed and aperture as if there was no flash attatched! (Except of course for speed that will exeed the max sync speed (1/180 fro the K10D) The result is often using to large F- stops, regardless of the fact, that there might have been light (power) enough for a better aperture!
You can of cource use Av, but then you never know if the flash is actually powerfull enough. And - if there's available light present - the speed may very well be to slow to freeze subject or camera movement. So, I always use "M" mode for flash photography. I will then evaluate the avaliable light, need for speed, DOF etc. IMO a good flash system would mean that the camera would KNOW (read) how powerfull the flash really is - and compare the data to the current focusing distance and to the amount of available light - and THEN decide/suggest the speed and the aperture - or ISO for that matter. Hey - I should take out a patent on this! Or perhaps someone already did? Nikon has some kind of 3D flash system, right? I can confirm, that AE will still work without a didcated flash - except for the sync speed limit, that will NOT be restricted to a useable sync speed. A simple check: If there's a flash ready light in the viewfinder (dedicated flash) - the sync speed limit will NOT be EXEEDED - no matter which MODE is used.

A pity that it is utter twaddle. My assumtion from those statements is that the older flashes will not do the "automatically set shutter speed and give 'ready' indication in the viewfinder". What Pentax calls "dedication". If the body will trigger the flash in manual mode, then auto must work. It requires the same trigger and makes its own decision as to when to quench. ----------------------------------------- Email sent from www.virginmedia.com/email Virus-checked using McAfee(R) Software and scanned for spam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net -- No virus found in this incoming message.
