Hey all. Haven't posted for a while, so I'm hoping the software lets this through... Lately I've been looking at getting a flash for my K200. Never had a flash before, but I'm interested in heading in that direction. I'd probably use it mostly for people shots (kid shots really) and indoor miscellaneous still life/macro. I'm considering the Sigma EF-530 DG ST. Anyone have any thoughts and/or suggestions? Looking for something cost-effective, probably no more than two, two-fifty including postage.
