Originally posted by Sagitta I own a Bolt flash. Its P-TTL (though its not advertised as such) and does a very decent job for the money I spent. It also practically sips the juice from its batteries - I've yet to actually drain the thing to the point of needing to swap the batteries out in casual use. I suspect my K-3's grip would burn through juice faster than the flash would. VS-510P Wireless TTL Shoe Mount Flash for Pentax & Samsung Cameras Its also on sale for only $140 at B&H.
