Am using D90 with built-in flash. Tried using Sigma 10-20mm lense (nikon mount) with flash. Saw that my picture has a shadow at the bottom of my picture. Seems to be from the flash that cast on the lense.
1. Is this because the lense is too wide?
2. Is this because of the built in flash? Need to get a flash that is higher?
3. Anyway to overcome this? I have no issue on some shots with flash.. strange...
thx in advance for advice..
