I bought a GF3+14mm a while back from Sammys when they were clearing them out...sold the 14mm and gave the GF3 to my girl along with my 14-150mm. Well, she gets a shadow in pics at the wide end when she uses the built in flash. I was thinking of getting her a G Vario 14-42 f/3.5-5.6 Mega OIS lens. Does anyone know if this lens causes a shadow or not? Any other cheap (used 100 dollars-ish) zooms that for sure dont cause a shadow?
