Originally posted by Ash So P-TTL leaves a little to be desired, but once understood and used with those nuances in mind can actually give reasonably consistent results.
I use my 540 all the time in doing weddings and it hasn't been overly off exposing the scenes for me. I guess I'm accustomed to the system and don't know any better. If I had a D300 or 500D/50D/7D to compare with, I might be more impressed...
thats the thing, when i got my pentax and came to this site i must admit that i was a bit of a fanboi at first
then i was reading more, and over time started getting access to using these other systems first hand in the line of fire (so to speak). And the more different equipment i used the more my fanboism died off. Reading online-line charts started making much more sense combined with real life experience.

the way my friend uses his Canon Speedlight is as follows
put camera in M mode
select aperture, shutter, and ISO.
flash is left in auto without pressing or touching anything.
take a shot, the flash provides the light needed to properly expose a scene (assuming your camera settings and the scene are not outside of the flashes output capability)
BRILLIANT!
with the K20 and 540 the only way i could get consistant results was to set the camera in A mode and mimic the iso/fstop that i manually set in the camera.
but then what happens when i want to quickly stop down to F2.0? The 540 wont even GIVE me an ISO 400 - F2 combination!!, i have to start doing math in my head to fool the god damn thing.
also PTTL works a bit better when its actually pointed at the subject, my attempts to bounce off the ceiling with PTTL on have always led to complete ruin.
I saw one of the canon photographers bounce his speedlight on-body off the celing shooting 40ish feet away with a telephoto and the scene was lit up like he had an extra light somewhere in the corner!

i'm going to dedicate my time to figuring pentax out to get some consistancy, it would be a shame to walk away after these years
