So, summary: AF540's may be electrically a bit fragile, and kinda
pricey, but they are friggen' workhorses, and will stand up to heavy
use. They lit up a concrete wall 12 feet high over an area at least 12
feet across, bright enough to be seen nicely at f/8.
Good to hear. ?I don't have a 540 but my 360 survived a fall onto a
concrete floor recently and continued on as if nothing had happened.
The only issue I have is that in manual mode with a manual-focus lens on
the camera, the manual zoom feature of the flash wants to reset itself after
every few shots. ?That was happening before the fall so maybe it's a feature
of electrical fragility as well.
It shouldn't be doing that. I don't think mine do, but I rarely use
them on-camera, and never with a manual lens, so I wouldn't normally
encounter this situation.
Mine reverts to default power on settings any time it's inactive long
enough to go to sleep.
When I first got it, it wouldn't zoom; had to send it to Pentax for
repair right out of the box.
Since it came back from them everything has worked, but it will only
hold settings until it times out. When I wake it up, I have to reprogram
any settings I was using all over again.
