RE: AF280T Flash Question
3 things I can think of: 1.) You had a bad battery in the first set, it shorted internally when it got warm and continued to discharge. 2.) The capacitor in the flash shorted internally when it got warm and wouldn't charge. When allowed to cool it started acting normalally again. 3.) The flash trigger circuit in the PZ isn't going 'open' fully. (Unlikely) My guess would be #1, set the flash to manual/full mode and fire it by hand 10-20 times. This will both test and 'form' (condition) the capacitor. If this is OK then repeat using the K2 to fire it. Try it on the PZ again, if it fails it is most likely a fault in the PZ trigger circuit. The 280 is compatible with any Pentax 35 SLR made and should work fine on any of them. Within camera limitations of course.

Re: AF280T Flash Question
The AF280 is a pretty robust flash unit. I would do as Don suggests and fire the unit 10 times or so by hand to see what happens. I also think the PZ-1 is pretty robust and will not be destroyed by any faults in the AF280. When I have not used the AF280 for months, I do notice an initial slowness to recycle after flash. This goes away after some use as the capacitors are re-formed to accept a charge. Since I know this happens, I make sure to fire the flash on full manual 5-6 times with older batteries. Then, I change to a fresh set of batteries and am ready to go with re-formed capacitors and better recycle times. Regards, Bob S.

Lewis Thanks, Don. I will follow your directions for #1. The Pz1 is okay with my AF400FTZ, so it isn't likely to be the PZ trigger circuit. Best, Lewis _ Dont just search. Find.
