EX1 and filters
Ok, I've had an EX1 since PC World kindly flogged off their stock for a ridiculous price, and I've been really happy with it in general. I want to start having a go with filters, specifically a polarising one. I see that Samsung reference a attachment for this, but cant find the Samsung branded one online at all. Does it exist any more and is it worth digging out, or are 3rd party ones decent enough to use?
A secondary question, anyone know the guide number of the built in flash. Looking for an external flashgun, and am wondering whether the sef42a is worth the extra over the sef20a.
