I just got the Minilux Zoom. One of the reasons I got it was for it's hot shoe. A great thing to have and I think the only point and shoot to have one. <p> But if I am to use an external flash unit. I have to set the aperture to match the flash unit. But I can't set the aperture on the Minilux Zoom! So how do I work around this problem? <p> What use is this hot shoe? <p> Please help! <p> Thanks.
