If you stick to brand name flashes, made in the last 15 years there should be no trouble.
-----Original Message----- From: Brad Dobo [mailto:brad.dobo@;rogers.com] I have a stupid question. :-) Ever since beginning photography, flash has been the most troublesome tool. However, what I'd like to know, is how safe is it to use other flashes on a Pentax camera? The Pentax literature doesn't suggest it and warns against major malfunction and nuclear meltdown. :-). Even some in the store tell me to go with Pentax, even when I'm looking at an expensive Metz. Has anyone here had any trouble, or ever heard of someone having trouble?
