JUST got my GX1 in the mail and I love it as an improvement over my GF1 which I never thought I'd replace. I also just got a Metz 36 AF-5 which is a decent flash; however, i'm not much of a flash photographer. The built in flash on the GX1 allows you to shoot at any aperture, while I can't seem to figure out how to shoot at anything besides 1.7 with the Metz. Nothing in the manual mentions working with an external flash either. I'd like to shoot sharper than a fully open lens with my flash. Anyone know how to achieve this? And now for the lens woes. I bought the GX1 because recently my photos just haven't been sharp & I was excited that there was finally a successor to the GF1, I tried another lens on the GF1 to see if it was the camera and they were out of focus too. I assume it's because I take that camera everywhere and it's been banged around so much. But now with the new body, the photos are better, but still slightly out of focus, grainy, and highlights seem to glow now and then. Is it possible there is something wrong with my Panny 20mm? There's no haze, scratches, or build up of any schmutz.
