For K100D:
1.) Does anybody have negative (or only positive) experiences with this Sigma flashgun? Does it works always or misses sometimes (on bouncing especially)?
And for original Pentax flash users:
2.) What about Pentax AF 540 FGZ? Does it always fires correct or misses sometimes too?
360 FGZ comes out since it doesn’t have swivel…
The budget is also important (otherwise I would just take 540 FGZ without questions).
