Please forgive me if this has been addressed; I'm unable to find anything conclusive
within search results.
Up till now, my cameras - S3iS, 40D, 50D - have had onboard pop-up flashes.
I've rarely used them, but they are occasionally needed or desired.
They've done a fairly good job on the few occasions I've used them.
But now that I have a 5D IV, there's bound to be an occasion from time to time
where a flash will still be desired. Problem for me, is that hotshoe flashes
all seem to be very large affairs, roughly the size of a smaller zoom lens.
I don't actually like to use flash, my methods prefer using available light,
so I likely wouldn't benefit from remote comptrolled whizz-bang features.
I've also zero experience with hotshoe flashes; simplicity is paramount.
The real meat of my questioning here has to do with physical size of hotshoe units:
Are there any out there which don't stand several inches above the top of the camera,
perhaps something which uses just a pair of AA or AAA batteries?
Inexpensive would be a major plus as well, say, around $50.
The Google found something which intrigued me, but it's an older unit
from Olympus(discontinued), and I haven't a clue if such is compatible with Canon.
What say you good people? Anything out there for me?
